Compact multiturn rotary encoder for mobile machines

Compact multiturn rotary encoder for mobile machines

Used for accurate position and speed measurement, rotary encoders must be primarily twofold: as compact and robust as possible. The new absolute encoders WV3600M and WH3600M meet exactly these requirements and are therefore predestined for use in mobile machines. Both have been specially developed to meet the requirements for commercial vehicles and are characterized by robustness, reliability and efficiency.

With an outer diameter of only 36 mm, the WV3600M and WH3600M rotary encoders are extremely compact, so that they can be used in the smallest installation space for position measurement. Based on the magnetic measuring principle, up to 65,536 revolutions can be measured absolutely. Thanks to the mechatronic multiturn, no additional battery is required for this, as a result of which the sensors operate particularly wear-free and maintenance-free. Both encoders are optionally available with a CANopen or SAE J1939 interface. These enable not only the fast and reliable transmission of position and status information, but also simple integration into the overall system. The two rotary encoders differ only in their mechanical design. Thus, the WV3600M is available with different solid shaft variants and common mounting types. The WH3600M, on the other hand, can be mounted directly on a rotating shaft due to the hollow shaft used. This means that less installation space is required.

Developed for use in mobile machines

Equipped with SIKO PURE.MOBILE technology, the two rotary encoders are ideally suited for rough use in mobile machines. They always deliver accurate and reliable position values even in a wide temperature range from -40 to +85 °C. Both sensors are already available in the standard variant with a salt spray-resistant housing. In order to be protected against water ingress and foreign objects, the sensors meet the requirements of protection categories up to IP67. Since construction and agricultural machines are usually cleaned with high-pressure cleaners, a variant with protection category IP6K9K is optionally available to users. Electromagnetic interference is a challenge for sensors. However, the WV3600M and the WH3600M were developed according to the requirements for commercial vehicles and therefore have a high EMC strength. In addition, the rotary encoders are tested according to the UN ECE R10 and are also suitable for use on public roads due to the accompanying E1 approval of the German Federal Motor Transport Authority.

One encoder – many possibilities

Thanks to the innovative design and a variety of electrical and mechanical options, the encoders can be flexibly configured. M12 plugs or cable outlet, solid or hollow shaft, singleturn or multiturn as well as different mounting types are possible. In this way, they can be quickly and easily integrated into the overall system. In addition, the two rotary encoders are optionally also available with DEUTSCH or AMP Superseal plugs.

Compact and robust draw-wire encoder

In combination with a SIKO draw-wire encoder, linear positions at a distance of up to 15 m can also be detected absolutely and precisely. Due to the compact design, the draw-wire encoders are used particularly in applications with limited installation space.
