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.
