Technical Overview
The Omron E32-ZC31N 2M is a compact right-angle reflective fiber optic sensor head with an M3 mount and a 2 m cable. Omron’s E3X-HD catalog lists IP67 protection, a 4 mm minimum bend radius and amplifier-dependent sensing distances up to 110 mm in GIGA mode, 50 mm in standard mode, 46 mm in high-speed mode, and 14 mm in super-high-speed mode. The catalog also lists a 5 µm representative minimum detectable target with the specified amplifier configuration. The exact technical specifications are confirmed, but current sales status for this model was not established.

Suggested applications
Engineering suggestions require suitability checks for your installation.
1. Coaxial reflective target sensing
A coaxial fiber arrangement can help reduce alignment effects when sensing small or irregular targets.
Potential use
Install the M6 head coaxial to the target and tune the compatible amplifier; verify the actual target surface, range and operating mode.

2. Machine sensing in limited space
The straight head and flexible routing can support optical sensing where a conventional sensor body is difficult to fit.
Potential use
Route the 2 m fiber without exceeding its 25 mm minimum bend radius and confirm environmental fit with the IP67 head rating.
