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.
For Ac Switches
A Thyristor Is Triggered When Oscillation Stops Due To The Presence Of Metal . This Thyristor Is Connected In Series With A Bridge And This Series Combination Is Connected To The Ac Load.

FAQs of Inductive Proximity Switches:
Q: How do Inductive Proximity Switches work in metal industry applications?
A: Inductive Proximity Switches detect metallic objects without contact by generating an electromagnetic field. When a metal object enters this field, the switch activates, making them ideal for automation and safety in metal manufacturing processes.
Q: What are the benefits of using these switches with a current rating of 300AMP?
A: A 300AMP current rating ensures that these switches handle high-power industrial equipment safely, minimizing risks of overload and offering compatibility with robust machinery typically found in metal industries.
Q: When should these proximity switches be installed in industrial workflows?
A: Install these proximity switches during system setup or maintenance periods, especially when upgrading or automating metal processing lines to enhance detection accuracy and operational reliability.
Q: Where can the switches be sourced from?
A: The switches can be sourced directly from manufacturers, exporters, suppliers, and wholesalers based in India, allowing buyers to access quality products backed by a 1-year manufacturing warranty.
Q: What is the recommended process for integrating these sensors into existing equipment?
A: Integration involves securely mounting the switches at critical detection points, wiring them according to the provided schematic, and calibrating the sensor for the specific metal object sizes encountered in your workflow.
Q: In what ways does the 1-year warranty benefit customers?
A: The 1-year manufacturing warranty assures buyers of product reliability, covering any defects or malfunctions within the warranty period. This reduces maintenance costs and instills confidence in industrial operations.
