IP55 Rated Infrared Beam Sensor for Outdoor Security and Automation
The JUTAI IR-20M Infrared 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.




- IP55 Protection: Effectively blocks dust ingress and resists low-pressure water jets from any direction
- UV & Corrosion Resistance: Rubberized, UV-resistant casing prevents degradation from sunlight and harsh weather
- Wide Temperature Adaptation: Operates stably from -10°C to +60°C, adapting to most climates
- 20-Meter Detection Range: Provides stable, focused beam for wide openings and perimeter security
- Anti-Interference Performance: Optimized infrared beam minimizes false triggers from ambient light, rain, or dust
- Intuitive Status Feedback: Red LED indicator for quick alignment and real-time status checks
- Universal Power Compatibility: Works with 12-24V AC/DC power supplies
- Versatile Relay Output: SPDT relay with COM, NC, and NO terminals for universal compatibility
- Dual Mounting Options: Supports wall mounting and metal surface mounting
- Simplified Wiring: Clear terminal labeling reduces installation errors
- Entrapment Prevention: Meets safety requirements for automated doors, gates, and barriers
- Robust Electrical Specifications: TX max operating current ≤25mA, RX max operating current ≤35mA
- High Relay Rating: Contact rating up to 500mA @ 48V AC/DC for industrial automation loads
