British Encoder 121 Incremental Modular Encoder

Brand: British Encoder

A reliable modular encoder that requires no calibration, gapping, or special tools to install! BECo has taken the performance of modular encoders to a new level with the Model 121 Auto-Aligning Modular Encoder. This new and innovative design provides simple, reliable, hassle free installation. Simply tighten the shaft clamp, install the mounting screws, and you’re done!

The Model 121 incorporates the latest Optical ASIC technology for greatly enhanced performance. Common problems with other modular encoder designs are warping and deflection, caused by their extensive use of plastic, both of which are virtually eliminated by the Model 121’s all metal construction. 

For brushless servo motor applications, the Model 121 can be specified with three commutation tracks to provide motor feedback. The optional 100°C temperature capability allows servo motors to operate at higher power outputs and duty cycles.

With its state-of-the-art technology and durable, all-metal construction, you can be confident your Model 121 is the finest modular encoder available anywhere.

Common applications: Servo Motor Control, Robotics, Speciality Assembly Machines, Digital Plotters, High Power Motors.
