JUTAI IR - 20 Infrared Photo Sensor: Ensuring Outdoor Detection Excellence
I. Introduction
The JUTAI IR - 20 infrared photo sensor is a sophisticated device designed to meet the demands of outdoor detection applications with precision and reliability.
II. Features and Specifications
A. Prominent Features
- Wide Application in Door Automation
- As a solitary beam detector, it finds application in various automated doors. The integrated amplifier in the transmitter-receiver unit emits an infrared beam that is resistant to external light interference.
- The self-detecting function is crucial for sliding doors. It ensures the door's safe operation by halting and retracting when the beam is interrupted and resuming closure once the beam is restored.
- Robust Weather Resistance
- With an IP65 rating and rubber casing, it can withstand the rigors of outdoor environments, including exposure to sunlight, rain, and dust.
- Long Detection Range
- The maximum detection range of 20 meters allows for effective coverage in large areas. At a low mounting height, it still maintains a reliable detection range of 2 - 20 meters.
- High-Quality Components for Consistent Performance
- German infrared lamps provide stable distance detection and light resistance, while Japanese Omron relays ensure seamless integration with different door operators. SMT production ensures batch quality.

III. How It Works
The sensor works by transmitting an infrared beam. When an object obstructs this beam within the detection zone, it changes the signal received by the receiver. In sliding door applications, this change prompts the self-detecting mechanism to control the door's movement. In security systems, it can trigger an alarm signal upon beam interruption.
IV. Installation Guidelines
- Open the front panel of the IR - 20M.
- Insert the cables into their respective housings and secure the base to the wall using the appropriate mounting method.
- Connect the power supply within the specified voltage range.
- Verify the red LED status on the receiver; it should be off with correct positioning. Interrupting the beam should activate the LED.
- Cover the sensor with the front panel and fix it in place.
- Test the relay response by repeatedly interrupting the beam.
V. Application Areas
- Gate and Door Automation
- Ideal for body induction in gates and anti-burglar detection in doors and windows.
- Security Systems
- Suitable for security setups in schools, commercial buildings, hospitals, and homes.
VI. Summary
The JUTAI IR - 20 sensor is a reliable and efficient solution for outdoor detection tasks.
