MS-228, M8 Threaded Cylindrical Sensor

  • Drawing of MS-228 Threaded Sensor

Features

30W Contact Rating. Normally Open contact. Three sensitivity bands. Sputtered Ruthenium Contact. Higher Shock Limits. 0.75 mm pitch M8 Threaded Barrel.

Benefits

Omni-polar. Does not require power for operation. RoHS Compliant. Not ESD Sensitive. Various Cables and Connectors Available. For rugged industrial use.

Description

This M8 threaded brass sensor is built for mounting in threaded holes and switch up to 30W loads. It is particularly useful in industrial applications where distance adjustments need to be made every now and then. Various activating distances are available depending on the magnet and the AT band used. This sensor can be supplied with non-standard connectors on request. All sensors are tested 100% for Operate AT, Release AT, Static Contact Resistance and Variable Contact Resistance before packing. Being an omni-polar device, this sensor can be actuated with either a north pole or a south pole or both. Choosing the right AT band, magnet strength, and operating axis, will restrict the number of operates and releases to one.
