Operating Temperature
Operating Temperature fo Proximity Switches is 0 to 55° C & Temperature up to 100° C can be manufactured on request.
Protections
AC Proximity Switches are protected against transient and surges. DC switches are protected against short circuit and reverse polarity.
Mounting
Switching Hysteresis
This is the difference between Switch ON and Switch OFF point of the switch. This is adjusted within 5% to 15% of the specified sensing distance.
