This document is about a product manual of IRB-RET, a retroreflective infrared photoeye product produced by EMX Industries, Inc. The product features include: external entrapment protection device type B1, non-contact sensor, and can be used for automatic gates and doors.
This manual provides step-by-step instructions for installing and configuring the EMX IRB-RET retroreflective photoeye for use with automatic gates and doors. It covers wiring diagrams, monitoring methods, and troubleshooting common issues. The device operates up to 60 feet and supports multiple monitoring configurations including normally closed, 10K resistive termination, and pulse methods. Installation requires aligning the photoeye with a reflector and verifying operation with an obstruction test.
The manual includes detailed wiring diagrams for different monitoring methods, configuration tables for DIP switches, and troubleshooting tips for common problems such as signal reflection or misalignment. It also specifies power requirements (6-40 VDC, 12-24 VAC) and environmental ratings (NEMA 4X).

| Dimensions (L x W x H) | 3.1” (79 mm) x 2.7” (69 mm) x 6.6” (168 mm) |
| Environmental Rating | NEMA 4X |
The operating range is 5 ft (1.5 m) to 60 ft (18.3 m).
It requires 6-40 VDC or 12-24 VAC (on only).
Stand 4 to 6 feet away, align the reflector with the photoeye, and slowly back up to the opposite end of the detection zone. Move the reflector left, right, up, and down to find the detection pattern.
