Infrared Safety Sensor for Sliding Doors Garage Doors and Gates

The JUTAI IR-20 Infrared Safety Sensor (also called Infrared Photocell, Beam Sensor, or IR Sensor) is a professional-grade through-beam detection solution engineered to enhance safety for sliding doors, garage doors, and industrial/commercial gates. Comprising a matched transmitter (TX) and receiver (RX), it creates an invisible 30-meter infrared beam that reliably detects obstacles, preventing entrapment, collisions, and operational hazards.

Operating on a simple yet robust through-beam principle, the IR-20 sensor emits a focused infrared beam from the TX to the RX. When the beam is interrupted by any object—whether a person, vehicle, pet, or debris—the RX's internal relay triggers instantly, sending a signal to the door/gate controller to stop closure, reverse direction, or pause operation.

Constructed with UV-resistant engineering plastic and a rubberized casing, the sensor pair withstands outdoor elements (dust, rain, sunlight) and temperature fluctuations. It's designed for 24/7 continuous duty in high-traffic or safety-critical environments, ensuring reliable performance where safety cannot be compromised.

• IP55 Ingress Protection: Effectively resists dust ingress and low-pressure water jets from any direction, enabling direct indoor/outdoor installation without additional shielding.
• Wide Voltage Compatibility: Operates on 12-24V AC/DC (non-polarized), seamlessly integrating with standard door/gate power supplies and control systems.
• Temperature Resilience: Functions stably from -10°C to +60°C, adapting to diverse climates (from cold winters to hot summers) and working conditions.

• Long-Distance Performance: Delivers a stable, focused infrared beam with a maximum range of 30 meters, suitable for wide door/gate openings and large access areas.
• Anti-Interference Technology: Optimized optical design minimizes false triggers caused by ambient light, rain, or dust, ensuring accurate detection in complex environments.
• Intuitive Status Indicator: The RX features a red LED—off when the beam is unobstructed (normal operation) and on when interrupted—for quick alignment and real-time status checks.

• Dual Mounting Options: Supports wall mounting (3x 5mm drill holes with screw anchors) and metal surface mounting (3x 3mm self-tapping screws), adapting to diverse installation scenarios.
• Versatile Relay Output: SPDT (Single Pole Double Throw) relay with Common (COM, terminal 4), Normally Closed (NC, terminal 5), and Normally Open (NO, terminal 6) terminals, compatible with any door/gate controller, PLC, or alarm system.
• Simplified Wiring: Clear terminal labeling (TX: 1-2 for power; RX: 1-3 for power, 4-6 for relay output) reduces installation errors and saves setup time.

• Entrapment Prevention: Meets critical safety requirements for automated doors and gates, preventing collisions and entrapment of people, pets, or objects.
• Industrial-Grade Reliability: High-quality components and robust casing ensure long-term performance in high-frequency use scenarios (e.g., shopping malls, warehouses, residential complexes).

• Sliding Doors: Shopping malls, office buildings, airports, and hospitals—preventing entrapment during closure.
• Garage Doors: Residential and commercial parking areas—ensuring safe operation when vehicles, pedestrians, or pets are present.
• Industrial/Commercial Gates: Warehouses, factories, and residential complexes—detecting obstacles to avoid collision during gate closure.
• Access Control Systems: Perimeter security for doorways, gates, and restricted areas—triggering alarms or access denial when the beam is breached.
• Public Building Entrances: Train stations, schools, and retail centers—enhancing safety for high-traffic automated door/gate systems.

1. Mounting Preparation: Select a location with a clear line of sight between the TX and RX. For walls, drill 3x 5mm holes and install screw anchors; for metal surfaces, drill 3x 3mm holes for self-tapping screws.
2. Wiring Connection:
   • Connect 12-24V AC/DC power to TX terminals 1 and 2.
   • Connect the same power supply to RX terminals 1, 2, or 3 (voltage-matched).
   • Wire RX terminals 4 (COM), 5 (NC), and 6 (NO) to your door/gate controller or alarm system.
3. Alignment: Adjust the positions of the TX and RX until the RX's red LED turns off, indicating a stable beam connection.
4. Final Testing: Secure the front panels with the provided screws. Test by interrupting the beam—verify the RX LED turns on and the door/gate controller responds correctly (stops or reverses).
