Limit value switches with inductive contacts can only be used in combination with switching amplifiers and can supply up to 4 independent switching signals simultaneously. The switching amplifier supplies the switching signal as a binary output signal.
Possible switching states: normally open or normally closed contact
The switching points are set using red limit value pointers via an adjustment lock in the center of the instrument glass.
Inductive contacts must be supplied with power externally
Inductive contacts have a long service life as the switching process is contactless.
Precise switching point: 0.5% of the full scale value.
Suitable for industrial use, especially for vibration-damped oil-filled dial gauges
Approved for use in hazardous explosive atmospheres (ATEX type examination)
