Bourns Rotary Magnetic Encoders for Harsh Environment Applications

Bourns has introduced the EMS22, a new line of rotary magnetic encoders that offer design flexibility along with enhanced reliability and better performance than traditional optical and contacting encoders. The EMS22 products feature a Hall Effect application-specific standard product (ASSP) capable of producing four distinct waveforms including quadrature, direction/step, absolute and PWM waveforms. These encoders can be interconnected in a daisy-chain configuration for a serial read-output option, which is beneficial in the case where memory overhead and space for wiring each individual encoder separately is critical.
