Inductive Proximity Sensor PNP (Metal Object Detection)

Overview

The Inductive Proximity Sensor PNP is a robust, non-contact metal detection solution designed for industrial automation, robotics, and embedded systems. This 12mm cylindrical sensor reliably detects ferrous metal objects within a 4mm sensing range, making it ideal for position sensing, counting, and limit switch applications. Its PNP (Normally Open) output and wide 6-36V DC operating voltage ensure easy integration with most PLCs, microcontrollers, and industrial controllers.

Key Features

• Reliable Metal Detection: Detects ferrous metal objects without physical contact, ensuring long service life and high repeatability.
• PNP Normally Open Output: Provides a high signal when a target is detected, compatible with most industrial inputs and microcontrollers.
• Wide Operating Voltage: 6-36V DC allows use in various systems, from low-voltage hobby projects to industrial control panels.
• Compact 12mm Housing: Cylindrical design with threaded mounting for easy installation in tight spaces.
• LED Indicator: Built-in LED shows detection status for quick troubleshooting and setup.
• IP67 Protection: Dust-tight and protected against temporary immersion, suitable for harsh environments.
