Product Overview

The SE-120 is an Incremental Rotary Encoder can be used as a direct replacement for other brand encoders, with no blind holes to drill. The SE quadrature dual-shaft encoder combine the most routinely used features in one standard device and are available with a selection of five different resolutions (pulses/revolution). The cube-style unit uses an infrared light source and precision mechanical components to provide exact, repeatable counts. Mounting the encoder is quick and easy using the pre-drilled holes in the base flange or the housing mounting holes located at each shaft output. The double-ended, flat keyed shaft permits a choice of mounting positions. Chrome steel bearings provide 20% longer life than stainless steel bearings. To aid in troubleshooting, LEDs are located directly on the body to instantly verify correct output operation. Quadrature output is standard and can be externally scaled to provide any engineering unit (RPM, angular position, feet/min).
  • 120 Pulses per revolution
  • High noise immunity
  • Short circuit protection
