Inductive Sensors

What is Proximity Inductive Sensors

We are Proximity Inductive Sensors Suppliers, Distributors & Importers in Mumbai, India. An inductive proximity sensor is a type of noncontact detector that uses an electromagnetic field to detect the presence of a metal object. The field changes whenever any metal object comes near it, and this sensor sends an electronic signal. Commonly utilized in factories and machines in the process of detection of metallic parts under dirty or hard conditions, dust, oil, and high temperatures, sensors have been reliable, precise, and immensely useful for positioning, counting, and monitoring speed in automated systems.

Proximity Inductive Sensors

Product Overview:

The CARLO GAVAZZI Proximity Inductive Sensors series ICB, M12, features extended range, nickel-plated brass housing types designed to meet industrial standards. These sensors are ideal for applications requiring a high sensing range and come with open collector NPN or PNP transistors. The sensors offer a 4 to 8 mm sensing distance and are available in both flush and non-flush types. They come in short- or long-body versions with a rated operational voltage of 10 to 36 VDC and a DC output of 200 mA, either NPN or PNP.
