Schlüter Automation & Sensor GmbH: History & expertise
In 1967 Lothar Schlüter, father of the current managing director Jens Schlüter, and still active in the company, founded Lothar Schlüter KG an industrial agency in Lehrte near Hanover, the then Lothar Schlüter KG, was at the forefront in the sensor business, already selling optical and inductive sensors.
As early as 1977, Lothar Schlüter and his colleagues at the time developed the first photo sensor in the M30 housing. Shortly afterwards, the first fiber optics were installed on the devices. This resulted in the Photo Sensor Universal System, or U-System for short, in 1981, which made the use of fiber optics and photo sensors even easier and more flexible. These fiber optics enable the use of high-performance photo sensors as reflex scanners or one-way light barriers, even in hard-to-reach places or under difficult environmental conditions such as heat, pressure, dust, fog, dirt, moisture, etc. Thanks to its high performance and flexible application options, the U-System quickly established itself on the market.
In the course of time, the production and delivery program was expediently expanded and supplemented with many components from the field of sensor technology. This is how Schlüter produces and supplies many innovative products that are unique on the market. For example, inductive sensors that work up to + 250 ° C, special light barriers for industrial ovens or capacitive special sensors for a wide variety of applications. Many products have been and are specially developed for customer-specific requirements and applications.
We at Wind Cluster, together with the experience and expertise of Schlüter, are looking forward to helping YOU find the best product for your specific needs.
At Wind Cluster we are proud to boast a vast range of products for the wind power industry, for many different applications, for use on small private owned turbines to large leading OEM windfarms. By creating lasting partnerships and distributing products for companies such as Schlüter Automation & Sensor GmbH we can not only offer the parts, but also the knowledge and expertise which accompany them.
Rotary Limit Switch for any Wind Turbine application
In yaw and pitch application with safety demands and with focus on precise adjustment -the right choice of Rotary Limit Switch is essential and will reduce wind turbine downtime and maintenance cost.
Rotary limit switches are used in wind turbines for managing and controlling the position of the nacelle (yaw control) and in some cases for pitch angle of the blades (pitch control).
Whenever the direction of the wind changes, the wind turbine nacelle will adjust accordingly to face perpendicular to the wind. Therefore, if the wind turbine nacelle rotates in the same direction for an extended period, the cables inside that carry the power from the generator down to the tower will become dangerously twisted. This is where the Rotary Limit Switch comes in, in simple terms it acts as a ‘detangler’ to ensure the cables don’t become twisted as the direction of the nacelle changes.
Rotary Limit Switches may be the good old conventional geared limit switches with rotary encoders referred to as yaw switches, or sometimes simply called “yellow boxes”.
Alternatively, now available are modern Electronic versions where the mechanical limit switches are replaced with programmable “softcams”. These newer versions are 100% maintenance free and offer more flexibility and a significantly longer lifetime. With the softcams (relays) the hysteresis becomes near to 0, because there are no mechanical movements in the microswitches.
Whatever the preferred technology for the specific wind turbine, the Rotary Limit Switches shall offer the capability to monitor the position of the nacelle and precisely manage the yaw drive to stop the rotary motion of wind turbine safely, for anti-twist protection of the power cable.
Wind Turbines operate in difficult thermal conditions with great thermal shifts between night and day, and they are subject to a variety of weather conditions such as water, dust, UV rays and brine. Therefore, for the rotary limit switches to have long electrical durability, accuracy of control and maintain resistance to extreme temperatures, it is essential that they have a high degree of protection against all possibly external interference. =
TER is the global market leader in this field and has acquired decades of experience in designing and manufacturing Rotary Limit Switches, providing a complete range from the conventional geared limit switched to the high fashion types offering the flexibility of programming, long lifetime and maintenance free operation.
At Wind Cluster we are eager to introduce you to the complete range of products from TER and to find the exact Rotary Limit Switch to match your wind turbine and business case best.

Can wind turbines operate in icy weather?
By WPED Contributor | March 1, 2021
By Sam Salem and Peter Nyegaard Jensen, Wind Cluster
The February 2021 freeze event in Texas attracted attention to wind turbine behavior in cold weather. Wind generation fell short of expected output but was not the main driver of the extensive power outages experienced across the state. Wind turbines have proved to generate power successfully in cold environments (many northern European countries get a significant portion of their electricity from wind power year-round) if the right preparations are made. And with many climate scientists expecting an increase in extreme weather events — including freezing temperatures — cold climate operation presents a niche market for wind turbine OEMs if they can keep blades spinning during winter.
The accumulation of ice on the surface of wind turbine blades may cause a harmful unbalance on the rotor, causing issues with production and structural design loads. Ice shedding from a blade can damage other blades, hit the roof of the nacelle or even cause hazardous situations for properties and passers-by.
A sensitive ice detection system will be the first step to provide an early warning. Looking at the weather, operational signals and using commercial ice detectors are a good starting point. There are many ways to detect ice formation: visual, mechanical, differential pressure, vibration, ultrasonic and optical. Modern ice detectors, like the ones by New Avionics Corp., are entirely optical. A tele-component light source and receiver monitor the opacity and refractive index of whatever substance is in contact with the detector probe. The optical ice detector works as a combined optical spectrometer and optical switch. A change in opacity registers as rime ice; a change in refractive index registers as clear ice. Modern ice sensors are generally lower in cost, lightweight and smaller in size. Relay contacts send a “go/no-go” or “ice/no-ice” signal to the host control system. They run on a DC power source of 8 to 30 V and need only 2 W of power to operate. Ice detection can be installed as a retrofit on the turbines in service.
In places like Texas, where wind-turbine icing is rare, stopping the turbine may be the cost-optimal solution. To minimize production loss due to icing, a combination of forecasting, detection and mitigation should be used. Better predictability also lets operators determine if and when to shut down wind farm operations altogether. There are instances when the sun can melt the ice. If models indicate severe icing probability, ice forming too thick or too fast, then stopping the wind turbines will be the action to take. In this case, forecasting plays a big role in mitigating outage risks.
In areas where icing may happen more often, it may be advisable to also consider ice-prevention measures. Ice prevention systems allow wind turbines to continue operating during winter months. There are a number of ice prevention systems that include passive systems such as ice-phobic or ice-resistant coatings, and active systems such as hot air or electro-thermal systems.
Ice detection and ice prevention technologies are improving, and their costs are going down. Energy production in the cold season with strong winds and high electricity prices is a big opportunity for wind turbines. But it requires better forecasting, early detection and risk mitigation.

Successful Spare Parts Strategy for Wind Turbines
After the wind turbine “infant mortality” lapse and OEM warranty period expire, the one shop-stop of Wind Cluster® offers access to more than 50.000 original wind turbine spare parts, repair materials, and accessories for all major wind turbine brands.
During the wind turbine “infant mortality period” and out through the first 2 – 5 years of asset operation, most asset owners and operators like to have OEM warranty and service contract. Once a sufficient operating history has been built up, the asset owners prefer to seek a more cost-
effective solution for the remainder of the wind turbine operational life given their newfound understanding of how to do service in a cost-effective ongoing manner. However, at the other end of an asset’s operational lifetime, there are wear-out failures due to the consumption of useful life for each component based on the operational history of the
machines. Maintenance, repair, and overhaul (MRO) activities are necessary to ensure safe and reliable
machine operation. Non-availability of spare parts could lead to machine downtime. Inventory costs, on
the other hand, need to be considered to attain economic machine operation. Spare parts strategy for old turbines will be different, somehow, from new turbines’ strategy. In some cases, parts for old turbine designs are not easy to find. Parts with long lead times entail high operation costs.
It’s important to know what parts of the wind turbine you need to focus on. Based on studies, the most
critical parts are the gears, which usually cause the longest downtime, the electric system, which has the
highest amount of failures, and the blades which have the highest purchase cost. Other critical parts are the control system and the sensors of the wind turbine, which both have a high amount of failures and a significant amount of the downtime and purchase cost.
The economic ordering quantity, or the optimal order size, is an important factor to minimize total
costs. If orders for multiple parts can be combined, this might save ordering costs and reduce the costs of
the total spare part management, even though the inventory has not reached the “reorder point” or the
previous parts review period has not yet ended.
Wind Cluster® offers a fast access to more than 50,000 original wind turbine spare parts, repair materials and accessories for all major wind turbine brands such as Vestas, NEG Micon, Enercon, Senvion, Suzlon and many more. We can assist with a fast, smooth and cost-efficient sourcing of spare parts. Send your request directly by e-mail and let Wind Cluster® make it easy to do wind business.
