JUTAI IR - 20 Infrared Photo Sensor: Your Ideal Outdoor Detection Partner
I. Overview
The JUTAI IR - 20 infrared photo sensor is a high-quality device engineered to provide accurate and reliable outdoor detection in a variety of applications.

II. Features and Technical Parameters
A. Notable Features
- Versatile Application in Door Systems
- This solitary beam detector is commonly used in automated doors such as sliding, shutter, and garage doors. The integrated amplifier emits an infrared beam that is less affected by external light.
- The self-detecting feature for sliding doors ensures smooth operation. When the beam is blocked, the door stops closing and retracts, then resumes closure when the beam is clear.
- Weather-Resistant Construction
- With an IP65 rating and rubber casing, it can resist ultraviolet radiation and abrasive particles, making it suitable for outdoor use in all weather conditions.
- Extended Detection Distance
- It has a maximum detection range of 20 meters. Even at a low elevation, it maintains a reliable detection range of 2 - 20 meters.
- High-Quality Components for Reliable Operation
- German infrared lamps ensure stable distance detection and light resistance, while Japanese Omron relays offer compatibility with various door operators. SMT patch production ensures batch quality.

III. Working Principle
The sensor transmits an infrared beam. When an object enters the detection zone and interrupts the beam, it changes the signal received by the receiver. In sliding door applications, this change triggers the self-detecting mechanism to control the door's movement. For security systems, an interrupted beam can send an alarm signal.

IV. Installation Instructions
- Lift the front panel of the IR - 20M to open it.
- Insert the cables into their housings and fix the base to the wall using suitable anchors or screws.
- Connect the power supply within the 12 - 24V DC/AC range.
- Check the red LED on the receiver; it should be off with proper setup. Interrupting the beam should turn it on.
- Cover the sensor with the front panel and secure it.
- Test the relay response by interrupting the beam several times.
V. Applications
- Gate and Door Automation
- Used for body induction in gates and anti-burglar detection in doors and windows.
- Security Systems
- Suitable for security setups in educational institutions, commercial complexes, medical facilities, and residential areas.
VI. Conclusion
The JUTAI IR - 20 sensor is a reliable choice for outdoor detection needs.
