FSH21-N Annular Proximity Switch Product Introduction
The FSH21-N annular proximity switch is a non-contact detection device specifically designed for 21mm standard detection distance. Featuring a unique ring-shaped sensing structure, this product ensures reliable identification of both metallic and non-metallic objects passing through its central aperture. The optimized electromagnetic field distribution enables precise detection of target objects, making it ideal for automated systems requiring through-beam sensing in confined spaces.
The annular sensing zone is engineered with precise dimensional calculations to maintain stable detection of 21mm standard-sized objects. The fully sealed enclosure provides IP67 protection against dust, moisture, and oil contamination. Built-in temperature compensation ensures consistent performance across -25℃ to +70℃ operating environments.
This sensor finds extensive applications in industrial automation systems including material handling, production line counting, and rotary equipment monitoring. The through-hole design allows unobstructed passage of cylindrical materials while detecting their presence. Compatible with 10-30V DC power supply, it supports both PNP and NPN output configurations for flexible system integration.
Technical specifications include 21mm±0.5mm detection distance and <1ms response time, meeting high-speed production requirements. The hybrid housing combines 304 stainless steel with engineering plastics for durability and lightweight construction. Multi-directional LED indicators facilitate easy status monitoring during operation.
Advanced electromagnetic field control technology minimizes interference from adjacent equipment. The modular design allows multiple installation options via standard M18×1 threaded mounting, adaptable to various spatial configurations. Rigorous endurance testing confirms over 10 million operation cycles, ensuring long-term reliability in demanding industrial environments.
