MR342
ZapFREE® Size 58mm Fiber Optic Incremental Encoder
The MR342 series ZapFree® Fiber Optic Incremental Sensor is an entirely passive, intrinsically safe, fiber optic incremental rotary encoder – ideal for a wide range of harsh and hazardous environmental applications. The passive, all-optical sensor connects to the remote Controller via a standard duplex 62.5/125 multimode optical fiber link.
The remote MR340 Controller Modules transmit and convert optical signals to/from the sensor. The Controller’s multiple built-in interfaces insure compatibility with industry standard motor drives, PLCs, quadrature counters and motion control systems.
