The Position Monitor

The electronic position switch with six programmable switching outputs (each with one on and one off switching points) are available with numerous functions. The number of bits for multiturn operations, singleturn or multiturn ranges as well as the switching range inputs with invert option are programmable. They determine hysteresis values, counting direction and the unit, identification, last change and conversion factor.
