Two points of distance setting output

It has a transistor output which outputs at a distance set in two stages.
Switchable to PNP, NPN and Push-pull with one unit.
It is not necessary to select model by output type.

Distance setting output hysteresis

Hysteresis can be set in 0.1mm increments for distance setting output.

Filter function

It has a moving average filter, a spike suppression filter and an error suppression filter.
It is strong against noise or error data.


Various interface is available such as RS232C, RS422, RS485 and SSI.
