MS-324 Miniature Flat Pack Proximity Sensor

Does not require power for operation

Omni-polar device; actuates with either pole of magnet

Normally open (NO) contact, others available on request

Three magnetic sensitivity bands

RoHS Compliant and Lead-free

Various types of leads and connectors available

Actuator magnet available in same housing

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 and release AT, contact resistance and variable contact resistance before packing. Our products are completely Lead-free and conform to the RoHS directive.

Possible Magnet Actuations

Flat Pack Magnetic Proximity Reed Sensor Actuation Examples

A few examples of magnet actuation are shown above. Being an omnipolar 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.
