Description

SN04-N NPN DC 6-36V Inductive Proximity Sensor

The SN04-N NPN DC 6-36V Inductive Proximity Sensor is a non-contact metal detection sensor designed for industrial automation, counting systems, position detection, limit sensing, and DIY electronics projects. It operates on a wide 6-36V DC input range and provides an NPN output, making it suitable for use with PLCs, relay circuits, control panels, and compatible microcontroller interface circuits.

This sensor detects metallic objects without physical contact, which helps reduce mechanical wear and improves reliability in continuous operation. Its compact body and simple 3-wire connection make it easy to install in automation systems, conveyor mechanisms, CNC machines, robotic setups, and other metal object detection applications.
