MS-324 Miniature Flat Pack Reed Sensor with Actuator
Features
10W Contact Rating. Normally Open contact. Three sensitivity bands. Sputtered Ruthenium Contact. Higher Shock Limits. Easy Screw Mounting.
Benefits
Omni-polar. Does not require power for operation. RoHS Compliant. Not ESD Sensitive. Various Cables and Connectors Available. Actuator with same Housing available.
Description
This screw mountable sensor can be mounted with M3 screws and can switch moderate loads of 10W. 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.
