Product information "Hall Effect Proximity Switches CYKN8-20DL2, Power Supply: 8-30V, Output: 200mA Open single output (NPN)"
A Hall Effect proximity switch is a non-contact electronic switch, which consist of a permanent magnet or ferromagnetic part as trigger intermediary and a Hall Effect sensor IC. The Hall sensor IC detects the change of the magnet field when the permanent magnet comes in the close proximity to it and generates an electric signal. This signal is amplified and rectified to control the output signal of the switch. Compared with magneto-electric, optoelectronic and capacitive proximity switches, Hall proximity switches have the advantages of good output wave shape, high stability, low costs, unaffected by oil, dirt and vibration, and wide operating temperature etc. They are very suitable for integrating in PC systems and various kinds of industrial control equipments, and are optimal switches for position control, speed measurement, counting, direction detection and automatic protection etc.
