An Inductive Proximity Switch is a non-contact sensing device used to detect the presence or absence of metallic objects (typically ferrous metals) without physical contact. It operates based on the principle of electromagnetic induction, making it ideal for use in harsh and industrial environments.

A reliable and cost-effective M18-sized (18 mm diameter) inductive proximity sensor with NPN, Normally Open (NO) output. Designed for industrial automation use, it offers metal detection with basic protection, rugged build, and easy integration for standard PLC/switching systems.

These sensors are designed for reliable metal detection in automation environments. They feature compact metal housings, built-in protection, LED status indication, and dual-output configurations ideal for demanding industrial applications.

This M18 DC 3-wire sensor is designed for rugged, high-reliability detection of metal targets in industrial automation. Its metal housing, extended sensing range, and PNP normally open output make it ideal for harsh environments and demanding installations where non‑flush mounting is required.

Designed for non-contact metal detection, the M50 DC 3‑Wire Inductive Proximity Sensor offers reliable operation in industrial automation environments. With a 50 mm housing diameter and DC output configuration, it suits medium-duty sensing under harsh conditions.

The M8 Proximity Sensor is a miniature cylindrical inductive sensor designed for reliable non-contact detection of metal objects. Ideal for applications with limited space, it offers accurate and consistent switching in compact automation systems, robotics, and industrial machinery.

An M18 AC NC Proximity Sensor is a type of inductive proximity sensor with an M18-threaded cylindrical housing, designed to detect the presence of metallic objects without physical contact.

Connector Type Proximity Sensors are non-contact sensors designed to detect the presence, absence, or distance of an object using electromagnetic fields. What distinguishes these sensors is the use of detachable connectors (rather than fixed cable wiring), making installation, maintenance, and replacement more convenient and reliable in industrial settings.

An NPN NC (Normally Closed) Proximity Sensor is a non-contact sensing device that detects the presence of nearby objects without physical contact. It uses the NPN transistor output configuration, where the switching element sinks current when activated. The NC (Normally Closed) configuration means the sensor's output is on (conducting) when no target is detected and off (non-conducting) when the target is present.

A Stainless Steel Proximity Sensor is an industrial-grade, rugged, non-contact sensing device designed to detect the presence or absence of nearby objects—typically metal—without physical contact. The sensor body is constructed entirely of stainless steel, providing excellent resistance to corrosion, mechanical wear, harsh chemicals, oil, and cleaning agents, making it ideal for food processing, pharmaceutical, marine, and harsh industrial environments.

Baumer is a Swiss manufacturer renowned for precision sensors in industrial automation. Their proximity sensors detect the presence or absence of metal (inductive), non‑metal (capacitive), or reflective objects (photoelectric) without contact. Baumer proximity sensors feature high switching frequencies, excellent repeatability, robust housings, and optional IO‑Link communication for smart diagnostics and parameterization.

A robust 3-wire DC inductive proximity sensor featuring a durable metal housing (nickel-plated brass or stainless steel), PNP logic, normally open (NO) output, and non-flush mounting, optimized for reliable metal detection in industrial automation.
