Capacitive Proximity Switches

Jayashree Electron offers a complete range of Proximity Switches such as Inductive Proximity Switches, Capacitive Proximity Switches, Optical Proximity Switches and Magnetic Proximity Switches.

The Series SW 505 Capacitive Proximity Switches are designed for sensing wide range of materials. These switches give a superior performance for detection of various non-metallic objects where Inductive type switches cannot function.
.

Working Principle:

The switch works on the principle of resonant oscillator circuit. A pair of brass/copper disc from the electrodes of a capacitor & the object acts as a dielectric media. The change in capacitance value, due to presence of object, is sensed by a precision integrated circuit. An effective output signal is generated at a preset value of capacitance.

Construction:

These are offered in tabular threaded housing from size M12 to M80. The enclosures are made of brass, stainless steel or engineering plastics. Standard models are provided with an integrated 2 meter long cable. Connector type versions are available with built-in male connectors.

Sensing Distance:

The nominal sensing distance of any size of switch is specified with water as standard object and tested at 25ºC. Depending upon the material of the object to be detected, the distance will vary. The sensitivity of the sensor is adjustable.
