Overview

Buy an M8 proximity sensor for detecting magnetic metal objects. It is an inductive proximity switch, available with 2 wire/NPN/PNP output modes, shielded/unshielded type installation, 1.5mm/2mm detection distance and a wide voltage range, can replace small switches and limit switches.

Feature

SUCH inductive proximity sensor uses an intelligent sensing chip with fast response and strong anti-interference capability to accurately detect nearby metal objects. With high repeat positioning accuracy, high switching frequency, and selectable NPN/PNP (NO/NC) output modes, it ensures stable and reliable operation in various applications.
It is equipped with a red LED indicator that clearly shows the operating state. When a metal target is detected, the indicator turns on or off according to the NO/NC mode, making on-site debugging and monitoring easier.
M8 inductive proximity switch offers vibration, dust, water, and oil resistance, supports a wide voltage range, and includes reverse polarity and short-circuit protection for direct PLC connection. Its robust construction allows it to replace small mechanical switches and limit switches while maintaining stable performance in harsh environments.

FAQ

Q1: What is the difference between the DC type (12–24V, 6–36V) and AC type (110–220V, 90–250V) M8 inductive proximity sensor? ❯

The DC type is designed for low-voltage control systems such as PLC inputs, automation controllers, or battery-powered equipment. The AC type works with high-voltage mains (110–220V) and is suitable for industrial machines without low-voltage circuits. Both detect metal objects, but their wiring and load requirements differ.

Q2: Can a 2-wire M8 inductive proximity sensor be connected directly to a PLC input? ❯

Yes, the DC 2-wire type can connect directly to most PLC digital inputs. Just ensure the PLC input can handle the sensor's leakage current and voltage range. If the PLC is overly sensitive, a small load resistor may be required to avoid false triggering.

Q3: What applications are suitable for an M8 inductive proximity switch? ❯

M8 inductive proximity switch is widely used in compact spaces or small machinery. Typical applications include metal part detection on assembly lines, position sensing in automation equipment, end-of-travel detection for cylinders, metal gear or shaft speed sensing, and presence detection in robotics or packaging machines.

No-brainer buy for replacing old proximity switches

Finally got my hands on these M8 thread sensors for our packaging line. I bought the AC type to match the old circuit panel. This M8 inductive proximity sensor fixed our indexing issues instantly. Readings don't jitter or skip beats. Super straightforward to mount in tight spaces. Great to have a few of these as cheap backups.
