Overview

Our M18 inductive proximity switches follow strict international sizing standards, ensuring a 100% seamless fit when replacing older, worn-out sensors from other major European or Asian brands. Choose the NPN NO variant for low-level switching logic common in modern digital control setups, or the PNP NO variant to comply with strict high-level safety standards mandated in heavy European automated machinery.

Feature

Industry-Standard M18 Threaded Housing: Precision-engineered with a rugged, nickel-plated brass alloy barrel, offering excellent mechanical strength, anti-vibration durability, and standard drop-in replacement for global machinery.

Dual Mounting Options & Standard Ranges: Available in Flush / Shielded (5.0mm sensing distance) for seamless embedded metal mounting, and Non-Flush / Unshielded (8.0mm sensing distance) for an extended detection field.

High-Frequency Responsive Switching: Delivers a rapid response speed of up to 1000Hz (for 5mm flush variant), ensuring millisecond-level precision timing for high-speed conveyor belts, CNC routers, and automated production lines.

Intelligent Triple Circuit Protection: Outfitted with an advanced built-in safety chipset providing Reverse Polarity Protection (against miswiring), Short-Circuit Protection (against load faults), and Surge Suppression.

Flexible 3-Wire NPN & PNP Logic: Supports standard 3-wire DC 10-30V operating voltage, allowing seamless integration with global PLC architectures (Siemens, Mitsubishi, Allen-Bradley) and open-source control boards.

IP67 Waterproof & Oil-Resistant Seal: The solid PBT sensing head combined with an upgraded, bend-resistant pure copper core cable ensures stable, continuous operations in harsh, greasy, and dusty factory environments.
