Technical Overview
The Omron E2E-S04N02-WC-B1 2M is a compact M4 threaded, unshielded inductive proximity sensor for detecting ferrous metal at a nominal 2 mm distance. It uses a DC three-wire PNP open-collector output in normally open mode, with a 2 m oil-resistant PVC cable and 10–30 VDC supply range. Omron lists the exact model as selling and standard stock; the SUS303 stainless-steel body 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 M4 threaded unshielded head can be considered where mounting space is limited and the target can be positioned within the sensor's specified 2 mm 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 3.5 kHz response and 10–30 VDC three-wire NPN output can suit fast discrete sensing when the actual target material, size, and mounting clearance are verified.
