Description
These ultra-miniature proximity sensors are suitable for low level switching applications, and have a size advantage over the other cylindrical sensors. 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. Cylindrical proximity sensors can be used in pneumatic cylinder end position sensing applications. 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.
