programmable limit switch / electronic

Indirect limit switches with electronic contact combined with dial thermometers, pressure gauges and electronic contacts are suitable for industrial use. All electrical components are placed watertight in casting resin on a plastic housing making it wear and corrosion free. the PLC, opto-couples or other electronic evaluation units with low voltage and current can be directly controlled due to a 3 wire type proximity switch with PNP switching input.The proximity switch is attached to a carrier arm, which is connected to the reference value. The control lug is moved with actual value pointer.The circuit is closed when the control hug enters the proximity switch.
