Balluff M18 Proximity Switch NPN, 5 mm Sensing, 3 m Cable

The Balluff M18 Proximity Switch is an NPN inductive proximity sensor with a 5 mm rated operating distance, designed for non-contact detection of metallic objects in industrial automation and control systems.

Overview

This sensor has a flush-mountable design with a shielded mechanical installation condition, allowing it to be installed level with surrounding metal surfaces without loss of sensing range. It offers an assured operating distance of 4 mm and a rated operating distance of 5 mm. With a switching frequency of 700 Hz, it is capable of detecting fast-moving objects, making it suitable for high-speed counting and sequencing tasks.

Key Features

• Clear function indicator for visual status confirmation
• Built-in protection against polarity reversal and short circuits
• Normally Open (NO) switching function with NPN switching output
• Sink wiring scheme for interfacing with programmable logic controllers (PLCs)
• Fixed 3.00 m PVC cable, eliminating the need for separate connectors

Construction and Specifications

The sensor has a cylindrical M18 threaded brass body and operates within a temperature range of -25 °C to +70 °C. It is powered by a 12-30 V DC supply. Product weight is 180 gm, with width 3.3, depth 1.5 and height 4.3.

The combination of flush mounting, fixed PVC cable and NPN output makes this sensor suitable for positioning and counting applications where a PLC interface is required.
