BALLUFF Proximity Switch M12, PNP, 2mm Range

The BALLUFF Proximity Switch (M12, PNP) is a precision-engineered, flush-mountable inductive sensor designed for reliable non-contact detection in demanding industrial applications. Built with a robust nickel-plated brass body and featuring a PVC cable connection, this sensor offers outstanding durability and resistance to harsh environmental conditions.

With an IP68 protection rating, it is completely protected against dust ingress and can withstand prolonged immersion in water, making it suitable for use in washdown areas or outdoors. The sensor operates reliably across a wide temperature range of -25°C to 70°C, ensuring consistent performance in both freezing and high-temperature environments. A key safety feature is its automatic recovery; the sensor becomes functional again immediately after any electrical overload condition has been eliminated, minimising downtime.

This PNP (sourcing) output switch is designed for easy integration into control systems, providing a stable signal when a metal target enters its 2mm nominal sensing range. Its cylindrical M12 threaded body allows for simple and secure mounting in standard fixtures.
