Inductive Proximity Switches (Barrel Round) DC Type

Inductive Proximity Switches (Barrel Round) DC Type are engineered using best available techniques and employing first grade components. These find their wide application where metallic target has to be sensed. These are fitted with exclusive sensors which are especially fitted to reduce inventory and wiring time for all DC applications. These are available in various technical specifications and range. These are acclaimed for uninterrupted performance and longer service life. Inductive proximity switches DC type are available in sizes from 4mm to 80mm diameter. These are mainly PNP and NPN type having Flush and Non Flush Mounting. These have NO / NC and NO+NC output logic.

Proximity Sensors are common ,durable and reliable solution for application requiring accurate,non contact detection of metallic objects in machinery and automation eqipments.

Working Principal
An inductive alternating r.f. field is developed at the front of the sensing surface of the proximity switch. this field is generated by the resonant circuit coil of the oscillator.

Energy is absorbed when a metal piece is brought into the r.f. field near the sensing surface, causing oscillation to stop. hence the demodulated voltage feeding the trigger disappears.

For DC Switches
The trigger operates rapidly when oscillation stops and this trigger switches the output transister, which can be either npn or pnp to drive an electronic circuit or relay.
