EMX IRB-MON2 UL325-Compliant Thru-Beam Photoelectric Sensor Black

Description

Product Overview

The EMX IRB-MON2 is a universal, UL325‑compliant monitored thru‑beam photoeye sensor engineered for demanding automatic gate and door applications. Constructed from a rugged black housing measuring 3.6 × 2.9 × 2.9 inches, the unit resists dust, moisture, and temperature extremes common in industrial settings. The sensor operates as a Type B1 non‑contact device, delivering reliable entrapment protection without mechanical wear. It supports multiple monitoring protocols—including NC, 10 kΩ resistive, 2‑wire 2‑frequency, and 3‑frequency pulse—ensuring seamless integration with a wide range of controllers. An integrated alignment LED provides visual confirmation of beam alignment, reducing installation time and minimizing field errors. The kit ships with a transmitter, receiver, mounting brackets, screws, and detailed installation instructions, while an optional hood (IRB‑MON2‑HD) is available for added environmental shielding.

Usage

Designed for automatic gates, sliding doors, revolving doors, and industrial access points, the IRB‑MON2 excels in high‑traffic, safety‑critical environments. Its thru‑beam configuration creates a reliable invisible barrier that instantly detects an object crossing the beam, triggering an immediate stop or reversal of motion to prevent entrapment. The sensor’s universal monitoring compatibility allows it to be paired with legacy controllers as well as modern PLCs, making it ideal for retrofits and new installations alike. Typical use cases include residential gated communities, commercial parking structures, warehouse loading dock doors, and secure facility entryways where compliance with UL325 safety standards is mandatory.

FAQ

What monitoring protocols does the IRB‑MON2 support?

The sensor is compatible with NC (normally closed), 10 kΩ resistive, 2‑wire 2‑frequency, and 3‑frequency pulse monitoring, allowing it to work with a wide range of controllers and safety relays.

Is the IRB‑MON2 suitable for outdoor installations?

Yes. The housing meets IP66 standards, protecting the optics from water jets, dust, and harsh environmental conditions, making it ideal for outdoor gate and door applications.

How does the alignment LED improve installation?

The built‑in LED emits a visible beam that helps installers verify proper transmitter‑receiver alignment before powering the system, ensuring accurate detection and reducing field adjustments.

Can I add a protective hood to the sensor?

Absolutely. An optional hood (IRB‑MON2‑HD) is sold separately and provides additional shielding against direct sunlight, rain, and debris, extending the sensor’s operational lifespan.

What warranty does EMX provide for the IRB‑MON2?

EMX offers a one‑year limited warranty covering defects in materials and workmanship, along with access to technical support and replacement parts throughout the warranty period.
