TOPENS TRF3 Reflection Photocell Sensor for Gate/Garage Openers Black

Description

Product Overview

The TOPENS TRF3 reflection photocell sensor is engineered to deliver a fast, reliable safety barrier for a wide range of gate and garage door applications. Built with a durable, UV‑resistant, flame‑retardant housing, the sensor withstands harsh outdoor conditions, operating comfortably within a temperature range of –4 °F to 122 °F. Its compact dimensions of 2.6″ × 2.6″ × 4.5″ and lightweight design (11.7 oz) make it easy to mount on poles or walls, while the 33‑foot (10 m) detection range provides ample coverage for most residential and commercial swing or sliding gate systems.

Powered by a DC source, the TRF3 does not require batteries, simplifying installation and reducing long‑term maintenance. The device features a retro‑reflective beam that instantly detects any obstruction in its path, triggering an immediate stop to prevent damage or injury. With a simple two‑wire connection, the sensor integrates seamlessly with generic gate openers, garage door controllers, and access control panels that accept a normal open or normal close dry contact signal.

Usage

Designed for outdoor use, the TOPENS TRF3 excels in residential driveways, commercial parking lots, industrial facilities, and security‑critical environments. Whether installed on a swing gate at a private residence or a high‑traffic sliding gate at a warehouse, the sensor reliably detects pedestrians, vehicles, and wildlife, ensuring safe operation. Its pole‑mount style allows placement at a minimum height of 8 in (20 cm) above the ground, providing optimal beam alignment while keeping the unit protected from accidental impacts.

The sensor’s versatility extends to garage door openers, where it adds an extra layer of protection against accidental closure when a person or object is in the door’s path. It also integrates with alarm systems and access control panels, delivering real‑time obstruction alerts that can be logged or used to trigger secondary safety mechanisms. Because the TRF3 does not rely on batteries, it is ideal for installations where power reliability is essential, such as remote gate stations powered by solar panels or low‑voltage DC supplies.
