Product Introduction

This High-Temperature Inductive Proximity Sensor is engineered to deliver reliable detection in extreme thermal environments where standard sensors fail. Rated for continuous operation from -25°C up to +150°C, it is an essential component for industries such as glass manufacturing, ceramics, metallurgy, and industrial baking.

The sensor features a rugged Nickel-plated Brass housing with an IP67 rating, ensuring protection against dust and moisture. Crucially, it is pre-wired with a high-quality Silicone cable, chosen specifically for its ability to withstand high heat without melting or becoming brittle. With standard sensing ranges of 5mm (Flush) and 8mm (Non-flush), and available in NPN, PNP, or DC 2-wire configurations, this sensor offers a durable, drop-in solution for automating high-temperature processes without compromising on speed or accuracy.
