Technical Overview
The Omron E2E-S05N03-WC-B1 2M is an M5 threaded, unshielded inductive proximity sensor for ferrous-metal detection at a nominal 3 mm distance. It provides a DC three-wire PNP open-collector output in normally open mode, 100 mA maximum switching capacity, a 2 m oil-resistant PVC cable, and 10–30 VDC operation. Omron lists the exact model as selling and standard stock; its SUS303 stainless-steel case is rated IP67.

Suggested applications
Engineering suggestions require suitability checks for your installation.
1. Compact fixture position detection
A small fixture may need a non-contact signal confirming that a ferrous pin or component has reached a defined position.
Potential use
The M5 threaded unshielded head can be considered where mounting space is limited and the target can be positioned within the sensor's specified M5 threaded sensing range.

2. Ferrous component presence sensing
Assembly and handling stations may require a discrete indication that a small steel component is present near a tooling point.
Potential use
The 2 kHz response and 10–30 VDC three-wire PNP output can suit fast discrete sensing when the actual target material, size, and mounting clearance are verified.
