Product Specification
Single Beam Photocell Sensor with 20M Range for Automatic Doors
The JUTAI IR-20M Single Beam Photocell Sensor is a professional-grade infrared detection solution engineered specifically for automatic door systems and safety-critical automation scenarios. As a through-beam sensor pairing a transmitter (TX) and receiver (RX), it creates an invisible, precise infrared beam with a 20-meter detection range, delivering reliable obstacle detection to prevent entrapment and enhance operational safety. With an IP55 weatherproof rating, wide voltage compatibility, and industrial-grade durability, it’s the trusted choice for automatic sliding doors, swing doors, high-speed roll-up doors, and access control systems worldwide.
Product Overview
Operating on a straightforward through-beam principle, the IR-20M sensor works by emitting a focused infrared beam from the TX to the RX. When any object—whether a person, vehicle, or obstacle—interrupts the beam, the RX’s internal relay triggers instantly, sending a signal to the automatic door controller to stop closure, reverse direction, or pause operation.
Constructed with UV-resistant engineering plastic and a rubberized casing, the sensor pair is built to withstand outdoor elements, dust, and temperature fluctuations. It’s designed for 24/7 continuous duty in high-traffic commercial, industrial, and public environments where reliability and safety are non-negotiable.
Core Features & Advantages
1. Weatherproof & Durable Construction
- 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 automatic door power supplies and control systems.
- Temperature Resilience: Functions stably from -10°C to +60°C, adapting to diverse climates and working conditions.
2. Reliable 20-Meter Detection
- Long-Distance Performance: Delivers a stable, focused infrared beam with a maximum range of 20 meters, suitable for wide door openings and large access areas.
- Anti-Interference Design: Optimized optical technology 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.
3. Easy Installation & Universal Integration
- 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 automatic door 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.
4. Safety-Centric Design for Automatic Doors
- Entrapment Prevention: Meets critical safety requirements for automatic doors, 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, airports, hospitals).

Typical Applications
- Automatic Sliding Doors: Shopping malls, office buildings, airports, and hospitals—preventing entrapment during closure.
- Swing Doors & Roll-Up Doors: Industrial facilities, warehouses, and retail stores—detecting obstacles to avoid collision.
- Garage Doors & Parking Barriers: Residential and commercial parking areas—ensuring safe operation when vehicles or pedestrians are present.
- 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, hospitals, and schools—enhancing safety for high-traffic automatic door systems.
Installation & Wiring Guide
- 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.
- 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 automatic door controller or alarm system.
- Alignment: Adjust the positions of the TX and RX until the RX’s red LED turns off, indicating a stable beam connection.
- Final Testing: Secure the front panels with the provided screws. Test by interrupting the beam—verify the RX LED turns on and the door controller responds correctly (stops or reverses).
