Product Introduction

This M12 High-Temperature Inductive Proximity Sensor is a specialized solution designed to withstand the most demanding thermal environments in industrial automation. Unlike standard sensors that fail at 70°C, this unit is engineered to operate continuously at temperatures ranging from -25°C up to +150°C. It is widely used in metallurgy, glass manufacturing, industrial ovens, and plastic injection molding machinery.

To ensure long-term reliability under thermal stress, the sensor comes pre-wired with a high-quality Silicone cable, which offers superior resistance to heat and prevents insulation failure. The rugged Nickel-plated Brass housing with an IP67 rating protects internal components from harsh conditions. Additionally, it offers impressive performance specifications, including high-speed switching (up to 1500Hz) and flexible output options (NPN, PNP, DC 2-wire), ensuring that high temperatures do not compromise detection speed or accuracy.
