Product Description

​The Omron E2E-S05S12-WC-B1 is a small-diameter inductive proximity sensor designed for precise metal detection in confined spaces. It features a cylindrical M5 threaded body with a 1.2 mm sensing distance and operates on a DC 3-wire system with a PNP open collector output in a normally open (NO) configuration. The sensor is pre-wired with a 2-meter PVC cable, facilitating straightforward installation. Its robust construction ensures reliable performance across a wide operating temperature range, making it suitable for various industrial applications.
