Product Specification
IP55 Rated Infrared Beam Sensor for Outdoor Security and Automation
The JUTAI IR-20M Infrared Beam Sensor (also known as IR Sensor, Photocell, or Through-Beam Sensor) is an industrial-grade detection solution engineered for outdoor security and automation scenarios. With an IP55 ingress protection rating, it excels in resisting dust and water jets, delivering reliable performance in harsh outdoor environments. Comprising a matched transmitter (TX) and receiver (RX), this sensor creates an invisible 20-meter detection beam, serving as a critical safety barrier for gates, doors, perimeter security, and industrial machinery worldwide.
Product Overview
Operating on a simple yet robust through-beam principle, the IR-20M works by emitting a focused infrared beam from the TX to the RX. When the beam is interrupted by any object (person, vehicle, or obstacle), the RX’s internal relay triggers instantly—sending a signal to stop closing doors, activate alarms, or pause automated equipment.
Crafted with durable engineering plastic and a rubberized casing, the sensor pair withstands UV radiation, temperature fluctuations, and outdoor debris. It’s designed for 24/7 continuous duty, making it ideal for high-traffic or security-critical outdoor applications where reliability cannot be compromised.
Core Features & Advantages
1. IP55 Weatherproof & Durable Design
- IP55 Protection: Effectively blocks dust ingress and resists low-pressure water jets (from any direction), enabling direct outdoor installation without additional enclosures.
- UV & Corrosion Resistance: The rubberized, UV-resistant casing prevents degradation from sunlight and harsh weather, extending service life in outdoor settings.
- Wide Temperature Adaptation: Operates stably from -10°C to +60°C, adapting to most climates (from cold winters to hot summers).
2. Reliable Long-Distance Detection
- 20-Meter Detection Range: Provides a stable, focused beam for wide openings (e.g., industrial gates, parking barriers) and perimeter security fences.
- Anti-Interference Performance: Optimized infrared beam design minimizes false triggers from ambient light, rain, or dust, ensuring accurate detection.
- Intuitive Status Feedback: The RX features a red LED indicator—off during normal operation (beam unobstructed) and on when the beam is interrupted—for quick alignment and real-time status checks.
3. Flexible Integration & Easy Installation
- Universal Power Compatibility: Works with 12-24V AC/DC (non-polarized) power supplies, seamlessly integrating with common door controllers, PLCs, and alarm systems.
- Versatile Relay Output: SPDT (Single Pole Double Throw) relay with COM (Common, terminal 4), NC (Normally Closed, terminal 5), and NO (Normally Open, terminal 6) terminals for universal compatibility.
- 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 outdoor installation scenarios.
- Simplified Wiring: Clear terminal labeling (TX: 1-2 for power; RX: 1-3 for power, 4-6 for relay output) reduces installation errors.
4. Safety-Centric & Industrial-Grade Performance
- Entrapment Prevention: Meets safety requirements for automated doors, gates, and barriers, preventing collisions or entrapment of people/objects.
- Robust Electrical Specifications: TX max operating current ≤25mA, RX max operating current ≤35mA, and relay contact rating up to 500mA @ 48V AC/DC—suitable for industrial automation loads.

Typical Applications
- Outdoor Gate & Garage Automation: Industrial gates, parking barriers, and garage doors—detecting vehicles/obstacles to avoid collision during closure.
- Perimeter Security: Invisible infrared fences for property boundaries, factory walls, or residential fences—triggering intruder alarms when the beam is breached.
- Automatic Door Safety: Outdoor sliding doors, swing doors, or high-speed roll-up doors in malls, hospitals, or industrial facilities—preventing entrapment.
- Industrial Machinery Safety: Outdoor material handling equipment, conveyor systems, or construction machinery—acting as a safety interlock for presence detection.
- Commercial & Public Spaces: Parking lots, train stations, and office building entrances—ensuring safe operation of automated access systems.
Installation & Wiring Guide
- Mounting Preparation: Choose a location with a clear line of sight between 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 & 2.
- Connect power to RX terminals 1, 2, or 3 (voltage-matched).
- Wire RX terminals 4 (COM), 5 (NC), 6 (NO) to your controller, PLC, or alarm system.
- Alignment: Adjust TX and RX positions until the RX’s red LED turns off (indicating a stable beam connection).
- Final Setup: Secure the front panels with provided screws. Test by interrupting the beam—verify the RX LED turns on and the relay triggers correctly.
