Omron E3T-SL11 2M Limited-reflective Photoelectric Sensor

BrandOmron
Model IdentifierE3T-SL11 2M
Official Part NumberE3T-SL11 2M

Technical Overview

The Omron E3T-SL11 2M is an ultracompact limited-reflective photoelectric sensor with a built-in amplifier, M2 mounting and a 2 m pre-wired cable. It uses a 650 nm red LED to detect a 50 × 50 mm white-paper target at 5 to 15 mm, with an NPN open-collector Light-ON output. The sensor operates from 12 to 24 VDC, has a 1 ms maximum response time and an IP67 enclosure rating. Omron listed the exact 2 m model as selling and standard-stock on 2026-09-11.

A compact limited-reflective sensor for close-range object detection with an NPN Light-ON output.

Suggested applications

Engineering suggestions require suitability checks for your installation.

1. Close-range part detection

The limited-reflective range suits installations where the target can be positioned within 5 to 15 mm.

Potential use

Use the specified white-paper reference target range as a selection baseline, then verify detection with the actual target and mounting geometry.

5 to 15 mm Limited-reflective Compact sensor

2. Small-feature detection

Omron specifies a minimum sensing object of 0.15 mm diameter at a 10 mm sensing distance.

Potential use

Evaluate the target material, shape and alignment at the intended sensing point before final machine installation.
