Santest SMR Series
Environmentally Resistant Linear Encoder
SMR series are the linear encoders using GMR (Giant Magneto Resistor) element. The sensor outputs A/B incremental signal according to relative movement between sensor and ferromagnetic scale of having 2mm pitch serration.
●Sensor adopts a highly-sensitive GMR element. It gives a stable output at velocity up to 15m/sec by high speed digital signal processing.
●SMR works without mechanical contact and can be used under harsh environments such as injection cylinder and die-casting machine.
●Serrated ferromagnetic scale shall be provided by customer.
