12-24V AC/DC Infrared Photocell Sensor for Automatic Gates & Garage Barriers

Upgrade your automatic gate, garage door, or sliding door system with this reliable 12-24V AC/DC Infrared Photocell Sensor. Featuring a matched transmitter and receiver pair with a built-in integrated amplifier, this CE-certified sensor produces a focused infrared beam up to 15 metres — keeping your entrance smart, safe, and responsive.

Key Features

Transmitter & Receiver Pair — The integrated amplifier generates a precise infrared beam for reliable object detection across your gate or door opening.
Anti-Interference Narrow Beam — Type I or II narrow infrared beam minimises false triggers caused by ambient or external light sources.
Up to 15-Metre Detection Range — Even when mounted as low as 20–40 cm from the floor, the sensor maintains a full 5–15 m effective detection distance.
Self-Detecting Safety Function — Once the beam is interrupted, the door immediately stops closing and reverses to its maximum open position. The door will not resume closing until the beam is fully restored, adding an important layer of safety to your automated entrance.
Wide Voltage Compatibility — Operates on 12–24V DC/AC, making it compatible with the majority of gate controller and barrier systems.
Durable ABS Construction — Compact, tough housing (10 × 4 × 3.5 cm) built to withstand everyday outdoor use.
CE Certified — Meets EU Low Voltage Directive standards (below 50V AC / 75V DC).

Frequently Asked Questions

Q: Is this infrared sensor compatible with both AC and DC gate systems?

A: Yes. The sensor operates on 12–24V AC or DC, making it suitable for a wide range of automatic gate controllers, garage door systems, and barrier units that fall within this voltage range.

Q: How far apart can the transmitter and receiver be installed?

A: The effective detection range is 5 to 15 metres, even when the units are mounted low (20–40 cm from the ground), making it flexible for standard residential and light commercial gate widths.

Q: What happens if something blocks the beam while the gate is closing?

A: The built-in self-detecting safety function triggers immediately — the gate or door stops, then reverses to its fully open position. It will not resume closing until the infrared beam path is completely clear again.

Q: Is the sensor suitable for outdoor use?

A: The sensor features a durable ABS housing and a narrow-beam anti-interference design that resists disruption from sunlight and external light sources, making it well-suited for outdoor gate and garage installations.
