Omron E32-DC200B 2M Diffuse Reflective Fiber Optic Sensor

Technical Overview

The Omron E32-DC200B 2M is a high-precision, diffuse reflective fiber optic sensor head engineered for advanced industrial object detection and positioning. Featuring a compact M6 cylindrical threaded body combined with a rigid 2.5 mm diameter sleeve extending 90 mm, this sensor integrates seamlessly into confined mechanical assemblies. The 2-meter, free-cut plastic core fiber allows for adaptable routing with a minimum bending radius of 25 mm (R25), covered by a durable PVC sheath. Built for harsh industrial environments, it features an IP67 protection rating and operates reliably across a wide temperature range of -40°C to 70°C.

Industrial Applications

1. Confined-Space Presence Detection in High-Speed Packaging

Utilizing the narrow 2.5 mm sleeve diameter and 90 mm extension, the sensor head reaches deep into tightly packed machine brackets on automated packaging lines where standard photoelectric sensors cannot physically fit.

Problem Solved

Resolves extreme clearance limitations and prevents false triggers in densely configured machinery, allowing reliable product detection without disrupting the mechanical layout.

2. Electronic Component Verification in Robotic Assembly Cells

Mounted above high-speed rotary index dials, the sensor verifies the presence and correct positioning of miniature electronic components immediately prior to pick-and-place robot cycles.

Problem Solved

Eliminates component crushing and robotic mis-picks by verifying part presence. The R25 bending radius allows the 2-meter optical cable to navigate cleanly through complex robotic cable tracks.

3. Part Ejection Confirmation in Harsh Machining Environments

Positioned near the ejection chute of automated CNC machining centers to verify that finished components have successfully exited the hazardous cutting zone.

Problem Solved

Prevents catastrophic tooling collisions caused by lingering parts. The IP67 rating ensures the sensor resists stray coolant splash and metallic dust, while enduring temperature fluctuations between -40°C and 70°C.
