MS-214 Miniature Cylindrical Sensor
Features
10W Contact Rating. Normally Open contact. Three sensitivity bands. Sputtered Ruthenium Contact.
Benefits
Omni-polar. Does not require power for operation. RoHS Compliant. Not ESD Sensitive. Various Cables and Connectors Available.
Description
This miniature cylindrical sensors are suitable for carrying moderate loads without sacrificing on size and can withstand more shock and vibration than the ultra-miniature variety. 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. Cylindrical Sensors can be used in pneumatic cylinder end position sensing applications. 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.
