Inductive Proximity Sensor Supplier

An Inductive Proximity Sensor is a non-contact electronic device used to detect the presence of metallic objects without any physical contact. These sensors work on the principle of electromagnetic induction — when a metallic target enters the sensing field, it changes the inductance, which is detected by the sensor to trigger an output signal. Inductive sensors are known for their reliability, high precision, and long service life even in harsh industrial environments.

 

SCB Industries is a trusted Inductive Proximity Sensor supplier in Kolkata, West Bengal, Odisha, Bihar, Chhattisgarh, Assam, Gujarat, Pune, and Vapi. We supply high-performance proximity sensors suitable for various industrial automation applications, offering both flush and non-flush types, AC/DC models, and different sensing ranges to meet diverse operational requirements.

This inductive proximity switch also known as a contactless proximity switch, is an ideal electronic proximity sensor.

When the metal detector is close to the sensing area of the sensor, the sensor can make no contact, no pressure, no spark, and send out the electric instructions quickly, accurately reflecting the position and the stroke of the moving mechanism, even for general stroke control, its positioning accuracy, operating frequency, service life, the convenience of installation and adjustment, and adaptability to harsh environment are incomparable to those of ordinary mechanical stroke switches and is widely used in machine tools, metallurgy, chemical, textile, and printing industries. It can be used as limiting, counting, positioning control and automatic protection in the automatic control system.
