Liftmaster CPS-RPEN4 Retro-Reflective Photo Eye
This unit is designed for commercial door applications with monitored retro-reflective sensing. It uses polarized beam technology to minimize interference from shiny surfaces and detects obstructions up to 50 ft. The model is suitable for high-traffic entrances where maintaining reliable safety sensing is critical. Best for commercial sites requiring interruption monitoring and anti-interference performance. Caution: ensure the unit is properly polarized to avoid false positives in reflective environments.
LiftMaster LMRRU Retro-Reflective Photo Eye And Reflector
This all-in-one kit includes the photoelectric sensor, a reflector, hood, mounting brackets, and installation hardware. It’s UL recognized and meets UL325 requirements with a 50 ft range. The package is convenient for those who want a complete turnkey solution. Best for new installations or upfits where having all components in one box saves time. Caution: verify that your gate opener supports the included kit accessories and mounting hardware before ordering.
Villalpand LMRRUL Retro-Reflective Photo Eye And Reflector
This model emphasizes compatibility with LiftMaster UL series gate operators and provides a long-range sensing distance up to 50 ft with a built-in heater for cold conditions. It includes a dedicated sensor cover, reflector with hood, and a multi-view LED status system for easier setup. Best for users who need a robust UL-compatible kit with straightforward installation. Limitation: the listing notes broad compatibility claims; double-check exact model compatibility with your operator before purchasing.
Gate Yuukey LMRRUL Retro-Reflective Sensor Kit (Alternate Listing)
Another Gate Yuukey listing emphasizes compatibility with LiftMaster UL series operators and includes a complete sensor kit with a reflector, brackets, and hardware. It highlights intelligent alignment indicators and a 4-wire interface for straightforward wiring. Best for installers seeking a familiar, easy-to-wire kit with guided alignment.

Buying Guide
What to consider when choosing a retro-reflective photo eye for gates or doors
- Compatibility: Confirm the sensor supports your LiftMaster UL model and the exact unit you plan to install.
- Range: Consider the sensing distance you need; most options here cap at around 50 ft, which suits standard residential and light commercial gates.
- Weather performance: Look for built-in heaters and corrosion-resistant housings for harsh climates or coastal environments.
- Installation complexity: Kits with reflectors, hoods, and mounting brackets simplify setup; if wiring on one side is a priority, check for single-side power options.
- Indicators and alignment: Visual indicators or intensity indicators speed alignment and reduce commissioning time.
- Durability and standards: UL recognition and NEMA ratings indicate reliability in demanding environments.
- Warranty and support: Ensure access to installation guides and compatibility checks from the seller.
