Industry standard size 25 incremental encoders offer reliable feedback with options up to 10,000 PPR, sealing, extended temp range and more.
Standard size 25 absolute encoders come with shaft or hub-shaft mounting, multiple protocols including SSI, BiSS, DeviceNet and more.
Single-turn hub-shaft 38mm size absolute encoder for servo motors. SSI, BiSS and SSI Gray protocols. Up to 22 bit single-turn resolution.
Optical encoders generate signals or pulses in response to a patterned disc rotating to reflect or transmiss light from an emitter to a sensor. An integrated circuit then processes the sensor data into digital feedback.
Optical encoders are just one of several feedback technologies used to track position and/or speed data. They are commonly used for applications where high accuracy and resolution are important criteria.
Optical encoders provide different output types based on whether they are incremental or absolute. Incremental type optical encoders output a continuous square wave with the crests corresponding to pulses. The output of the absolute optical encoders is a unique digital word or bit and is output in the set communication protocol such as BiSS or EtherNet/IP.
