APS-GMC Series

APS-GMC Series
Wiring-saving
The 2-wire design reduces the time spent wiring to two thirds of that with the conventional 3-wire design.
Power-saving
In comparison with the current consumption of 10 to 20 mA with the 3-wire design, the 2-wire design consumes a current only at 0.55 mA or less when the output is OFF (Leakage current), achieving power-saving.
Long operating distance
A longer operating distance allows easy settings.
