MR341 Encoder

ZapFREE® Size 11 Incremental Rotary Encoder

The MR341 Mini Rotary Encoder is a Size 11, small form factor incremental encoder offering resolution to 512ppr. It is inter-mountable with resolvers, synchros and conventional electronic-based encoders of the same size.

The MR341 Encoder is a 100% passive sensor which operates entirely in the optical domain. The sensor provides immunity to any electro-magnetic interferences such as lightning, radiation, magnetic fields and other harsh environment conditions. The innovative design provides 100% electrical isolation as well as immunity to high voltages – ideal for harsh environment applications such as feedback for welding robots, measuring anode position in smelters, and monitoring pantograph operation in electric rail applications.
