IP65 Sunlight-Resistant IR Sensor for Automatic Sliding Gates and Doors

JUTAI IR - 20 Infrared Photo Sensor: A Reliable Outdoor Detection Solution

I. Overview
The JUTAI IR - 20 infrared photo sensor is a cutting-edge device tailored for outdoor applications, offering precise detection capabilities in various scenarios.

II. Features and Technical Details

A. Key Features

1. ​Versatile Application Scope
   • This solitary beam detector is widely used in automated doors like sliding, shutter, and garage doors, as well as windows. It comprises a transmitter and receiver with an integrated amplifier emitting an infrared beam.
   • The self-detecting feature is a standout aspect, especially for sliding doors. When the beam is interrupted, the door halts closing and retracts fully, resuming closure only when the beam is restored.
2. ​Weatherproof Design
   • With an IP65 rating and rubber casing, it can endure harsh outdoor conditions such as rainfall and dust storms, thanks to its resistance to ultraviolet radiation and abrasive particles.
3. ​Extended Detection Range
   • Capable of detecting objects within a maximum range of 20 meters. Even at a low elevation (20 - 40cm above ground), it maintains a reliable detection range of 2 - 20 meters.
4. ​High-Quality Components for Optimal Performance
   • German-brand infrared lamps ensure stable distance detection and light resistance, while Japanese Omron relays guarantee compatibility with various door operators. SMT patch production ensures batch production quality.

III. Working Principle
The sensor operates by emitting an infrared beam from the transmitter. When an object enters the detection zone and interrupts this beam, it causes a change in the signal received by the receiver. In applications like sliding doors, this change triggers the self-detecting mechanism to control the door's movement. For security systems, the interrupted beam can send an alarm signal to a host.

IV. Installation Steps

1. Open the IR - 20M by lifting the front panel.
2. Insert cables into their housing and fix the base to the wall, using appropriate anchors or screws depending on the mounting surface.
3. Connect the power supply within the 12 - 24V DC/AC range.
4. Check the red LED on the receiver; it should be off with proper positioning and alignment. Interrupting the beam should turn it on.
5. Cover with the front panel and secure it with screws.
6. Test the relay response by interrupting the ray multiple times.

V. Applications

1. ​Gate and Door Automation
   • Used for body induction in parking barriers, gates, etc., and as anti-burglar detection for windows and doors.
2. ​Security Systems
   • Suitable for security setups in educational institutions, commercial areas, medical facilities, and residential premises.

VI. Conclusion
The JUTAI IR - 20 sensor is a reliable choice for outdoor detection, offering stable performance and easy installation.
