Inductive Proximity Switch

Industrial inductive proximity switch are exported and manufactured by us.

Principle of operation of Inductive proximity switch products are high frequency altering field at the sensing face. When any metallic material enters in the sensing zone of the switch, the field gets disturbed. A sensitive detector circuit senses this change which is further processed by amplifier circuit to produce output signal.

Object:

The sensing distance specified here is for object made of mild steel, having thickness of 1mm. Size of the object should be at least equal to the diameter of switch/ sensing face. For object other than mild steel, apply suitable correction factor.

Inductive Proximity Switch (2 wire AC switch) are manufactured and exported by us.

Two  AC proximity switches of type IS 2A :

Ac switches operated on  90-230 Vac and directly drive load like contactor or solenoid coil. Low voltage drop of 6 V across the switch makes it suitable to connect even two switches in series. Special protection against spurious signals is incorporated.

AC switches are not protected against short circuit of load. Hence care should be taken for proper wiring.

Inductive Proximity Switch (2 wire DC switch) can be availed from us at very affordable prices.

Namur sensor / two wire DC proximity switches of type IS 2D:

These are two wire current operated switches. The switch is designed for installation in hazardous areas. Switch draws current less than 3 to 4 ma in absence of metal and 1 ma in presence of metal. The switch is suitable for operation in hazardous area group classification i, ii a, ii b, ii c, as per is 5780-1980 temperature class t4 (certified by CMRS Dhanbad), when fed through an intrinsically safe controller on zener barrier. This amplifier unit detects change in current and further processes to give output signal. Amplifier unit along with power supply and output relay fitted in separate enclosure with ip30 or ip55 grade of protection. These switches are compatible with internationally available intrinsically safe controller.

Square Enclosure And Limit Switch Housing are a part of our wide range of products.
