Ferromagnetic Gear & Metal Proximity Sensor (P679 Series)
Direct ferrous metal (iron/steel) detection proximity sensor with built-in bias magnet — senses steel targets and gear teeth without an external magnet.
Product Details & Technical Specifications
1. Product Overview
Misensor P679 Ferromagnetic Proximity Sensors integrate a precision bias magnet with a high-sensitivity hermetically sealed reed switch or magnetoresistive IC. Unlike conventional magnetic sensors that require mounting a separate magnet on the moving object, the P679 directly detects carbon steel, iron cams, gear teeth, and hydraulic cylinder pistons.
