Optex HU-3 Heating Unit for Photobeam Sensor

Product Description

The OPTEX HU-3 is a dedicated heating unit designed for use with OPTEX active infrared photobeam sensors. It provides supplemental heat to keep the photobeam detector optics and internal components within their operating temperature range during cold-weather installations. Without adequate heating, photobeam sensors in low-temperature environments can experience condensation, fogging, or lens icing that degrades detection performance. The HU-3 is installed directly onto the compatible photobeam housing and is typically handled by security system integrators, electricians, or low-voltage technicians working on perimeter detection systems.

The HU-3 is suited for outdoor or semi-exposed photobeam sensor installations in climates where temperatures regularly drop to levels that can affect sensor reliability. Typical applications include perimeter security at commercial and industrial sites, access control entry lanes, and gate detection systems where year-round consistent beam alignment and optics clarity are critical. It is a replacement or add-on heating component for the OPTEX AX-series photobeam sensor product line.

Key Features

• Provides internal heating to maintain photobeam sensor performance in cold environments
• Designed specifically for OPTEX AX-series active infrared photobeam sensors
• Protects optics from condensation, fogging, and icing in low-temperature conditions
• Direct-mount design integrates with the existing sensor housing
• Sold as a single unit (each)

Compatibility

Designed as an OEM-style heating accessory for OPTEX AX-series photobeam sensors. Consult OPTEX documentation to confirm fitment with the specific photobeam model being serviced.

Installation Notes

Installation should be performed by a licensed low-voltage technician or qualified security system integrator. Disconnect and de-energize the photobeam sensor system completely before attaching or servicing the heating unit. Follow all applicable local electrical codes and the manufacturer wiring documentation for the specific AX-series sensor being serviced. Do not energize the heating unit until all connections are secured and the housing is properly closed and sealed.
