Product Description And Features
The 25MM ring proximity sensor is a non-contact sensor encased in a flame-retardant ABS housing, designed with a ring structure that allows for 360-degree detection of objects passing through. Equipped with dual LED indicators, it clearly displays both power and sensing status, enhancing ease of operation and monitoring, thereby increasing overall operational efficiency.
Offering a range of orifice sizes including 3/6/8/10/12/15/22/30MM, the sensor caters to diverse control system requirements, enhancing flexibility and adaptability in sensor deployment. It comes with either a 2M PVC cable or an M12 connector, and is rated with an IP67 protection level, ensuring stable performance even in harsh industrial environments.
