Single Infrared Beam Sensor

Products Description

Product Features

Single Infrared Beam Detection
Single beam infrared sensing technology provides reliable object detection for automatic gates, barrier booms, parking lot doors and access control systems. It triggers a signal once the infrared beam is blocked, reliably detecting pedestrians and vehicles crossing the beam. This helps prevent barrier gates from hitting cars or people, reducing safety accidents and compensation risks for your gate projects.

Relay Output with N.C. / N.O. Optional
Supports Normally Closed / Normally Open relay switch output, compatible with most gate control boards, barrier gate controllers and access panels. Flexible wiring selection matches different project requirements, so there is no need to change main control boards. This saves modification cost and engineering time for installers.

IP55 Weatherproof Enclosure
IP55 dust & water resistant rating, outdoor working available. Stable performance under rain, dust and temperature change, ideal for parking, driveway gate and roadside barrier applications. The weatherproof enclosure works stably outdoors against dust and rain, resulting in less after-sales failure and reduced maintenance trips and warranty costs for installers and end users.

Easy Installation & Simple Wiring
Compact oval housing design with pre-drilled mounting holes for fast installation. Clear terminal block on PCB board, simple wiring without complicated configuration. This quick and simple installation cuts down on-site construction time and labor cost for engineering teams.

High Anti-interference Performance
Built-in anti-interference circuit effectively resists sunlight interference and reduces false triggers in strong sunlight outdoor environments. It avoids false triggering caused by direct sunshine, so the gate system runs smoothly without unnecessary opening/closing, improving overall system stability. Low power consumption and long service life further lower power operating costs and reduce replacement cycles, building a better project reputation.

Application

Wide Compatibility for Gate Systems
Perfectly matched with automatic barrier gates, swing gates and sliding gates. Used as a safety anti-crush sensor to prevent gate/boom hitting vehicles or pedestrians. With flexible relay output and wide compatibility, it integrates easily into most gate systems without extra modification.

Certifications

Certified Quality: CE, FC, RoHS
Passed CE, FC and RoHS certifications. Stable circuit design with overvoltage protection, long service life and low failure rate. These certifications meet international import standards, so there are no customs clearance issues and the product is easy to sell in EU, US and global markets.

FAQs

Q1: What gate controllers is this infrared beam sensor compatible with?

A: It provides optional N.O. / N.C relay output, which works with most automatic barrier gates, sliding gates, swing gate main control boards on the market. You do not need to purchase extra adapter modules. Please confirm your controller supports relay signal input before purchase to avoid mismatching.

Q2: Can this sensor work outdoors under heavy rain and dust?

A: Yes. The enclosure reaches IP55 weather‑proof rating. It resists rain splash and dust accumulation for long‑term outdoor use in parking lots, driveways and access entrances. Please note it cannot be immersed in water; avoid installing it in positions with continuous water soaking.

Q3: Will strong sunlight cause false triggering or detection failure?

A: Our sensor is built‑in anti‑sunlight interference circuit, greatly reducing mis‑trigger caused by direct sunlight. While extreme strong glare may still have minor influence, actual performance is stable for most outdoor parking scenarios. Keep the transmitter and receiver out of direct facing toward the sun for best results.

Q4: What is the maximum sensing distance of this single infrared beam sensor?

A: Standard effective detection distance reaches 10 meters. Keep transmitter and receiver aligned properly. Obstacles between two units will block the infrared beam and trigger safety signal.

Q5: Is professional experience required for installation?

A: No special professional skills are needed. Pre‑drilled mounting holes and clear terminal blocks support fast wiring and fixing. Follow our user manual for wiring sequence. It is recommended that installation be completed by a qualified gate technician for project safety.

Q6: What happens when the infrared beam is blocked?

A: Once the infrared beam path is interrupted by people, vehicles or obstacles, the sensor sends safety signal to gate controller. The barrier gate will stop closing or reverse opening, preventing crushing injuries or vehicle collision, lowering safety‑accident liability risks for your project.

Q7: What should I do if the sensor works intermittently or unstable?

A: 1.Check whether transmitter and receiver are well aligned; slight offset will affect performance.
2. Check for dirt, spider webs or obstructions covering sensor lens. Clean the lens gently.
3. Double‑check wiring and power supply voltage.
4. Adjust mounting angle to avoid direct sun shining onto lens.

Q8: What is the warranty period for this infrared beam sensor?

A: We offer 1‑year warranty against manufacturing defects. Damage caused by wrong wiring, man‑made destruction or harsh over‑limit environment is not covered under warranty.
