Technical Overview

The Omron E32-LD11N 2M is a hex-shaped diffuse reflective fiber optic sensor head featuring an integrated lens and a right-angled M6 threaded head. Designed for stable detection and simple installation, it features an aperture angle of approximately 15° which provides a narrow field of view and higher power compared to standard sensors. The R2 flexible plastic fiber has a 2-meter cable length and supports free-cut capability. With an IP50 rating, it is built to perform within a temperature range of -40 to 70 °C and can reach a sensing distance up to 1260 mm depending on the amplifier unit used.

Key Features

Built-in lens achieves approximately 3 times higher S/N ratio than conventional units
Narrow 15° aperture angle restricts scattered light and reduces false reflections
Tool-friendly M6 hexagonal shape prevents cable damage during installation
Right-angled 90° cable exit is ideal for space-constrained environments
Flexible fiber with R2 bending radius supports dynamic bending applications
Free-cut capability allows the 2-meter polyethylene-sheathed cable to be cut to length

Industrial Applications

1. Precision Electronic Component Detection on Vibratory Feeders

On high-speed assembly lines, small electronic components must be counted as they exit vibratory feeders. The E32-LD11N 2M's right-angled (90° exit) head fits into tight spaces, and its integrated lens with a narrow 15° aperture angle focuses the beam to detect tiny parts without interference from the metal feeder walls.

Problem Solved

Solves the issue of false reflections from nearby metallic structures in compact assembly machinery, avoiding the need for complex mounting brackets.

2. Carton Presence and Position Sensing in Food Packaging

Inside cardboard cartoning and packaging machines, paper dust can quickly build up and cause standard photoelectric sensors to fail. Utilizing the E32-LD11N 2M with a high-power amplifier unit (like the E3NX-FA) achieves a long sensing distance of up to 1260 mm. The high optical S/N ratio (3x higher than conventional units) ensures stable diffuse reflective detection despite dust accumulation on the sensor face.

Problem Solved

Minimizes downtime caused by dust-induced sensor failures and false triggers in packaging facilities.

3. Matte Black Plastic Tray Detection on Robotic Pick-and-Place Arms

Robotic arms handling matte black plastic trays require lightweight, highly flexible sensors. The E32-LD11N 2M is extremely light (approx. 40g), and its R2 bending radius fiber allows the cable to twist and bend continuously on a moving arm. The narrow 15° field of view and high-power lens resolve the low-reflectivity challenge of black surfaces, ensuring stable tray presence detection.

Problem Solved

Prevents robotic crash errors or missed pickups of low-reflective black targets on active, fast-moving robotic joints.
