Proximity detectors are devices that use mutual capacitance between itself and object in order to detect its presence.[1]
There are many types of proximity detector. Common types include:
- magnetic proximity switch - see reed switch
- infrared proximity switch

- Magnetic proximity fuse
- Proximity sensor
- Touch switch, another device made possible by body capacitance
