♦ Does not require power for operation ♦ Omni-polar device; actuates with either pole of magnet ♦ Normally Open contact, others available on request ♦ Sputtered Ruthenium contact ♦ Three magnetic sensitivity bands ♦ RoHS Compliant and Lead-free ♦ Not Sensitive to ESD ♦ Various types of leads and connectors available ♦ Contact rating of up to 60W ♦ Actuator magnet available in same housing ♦
This MS-328 screw mountable sensor can be mounted with M3 screws and can switch loads of up to 30W. 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. Our products are completely Lead-free and conform to the RoHS directive.
This magnetic proximity sensor is suitable for use in the following applications and in many others: satellite television dish positioning, door sensing in domestic goods, heavy vehicles, door and window security, fork lifts, Top-loading washing machines, adjustable chairs and beds, fire safety doors, surveyor’s Wheels, cargo containers…

Example: MS-328-4-500-S
Denotes MS-328 proximity sensor in 25-30 Operate AT, with 500 mm cable length and Stripped to 5 mm.
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.
