JUTAI IR - 20 Infrared Photo Sensor: Ideal for Outdoor Detection Applications

I. Introduction

The JUTAI IR - 20 infrared photo sensor is a highly reliable and versatile device designed for a wide range of outdoor detection needs. Whether it's for gate opening mechanisms, security alarm systems, or anti - burglary applications, this sensor offers excellent performance.

II. Features and Technical Parameters

A. Features

1. ​Versatile Applications
   • Solitary beam detectors like the JUTAI IR - 20 are commonly used in automated sliding doors, shutter doors, garage doors, windows, etc. It consists of a transmitter and receiver with an integrated amplifier that emits an infrared beam.
   • The self - detecting capability of the IR - 20 sensor is especially useful for sliding doors. When the self - detecting beam is interrupted, the door stops closing and retracts fully. Once the beam is restored, the door resumes closing until it is fully closed again.
2. ​Weather Resistance
   • With an IP65 rating and rubber casing, it is highly resistant to ultraviolet radiation and abrasive particulate matter, making it suitable for outdoor environments. It can withstand rainfall, dust storms, and other harsh weather conditions.
3. ​Wide Detection Range
   • The maximum detection range is 20 meters, which can be adjusted according to different installation requirements. Even when mounted at a relatively low elevation (20 - 40cm above ground level), it can maintain a reliable detection range within 2 - 20 meters.
4. ​High - Quality Components
   • Infrared lamps use German brands to ensure stable distance detection and light resistance. Relays use Japan's Omron brand for compatibility with various door operators. SMT patch production is adopted to ensure the quality and accuracy of batch production.

III. Working Principle

The JUTAI IR - 20 sensor works based on the interruption of an infrared beam. The transmitter emits a narrow infrared beam (either Type I or II), which is designed to counteract external light interference. When an object moves within the detection zone defined by the transmitter and receiver, it interrupts the infrared beam. This interruption causes a change in the signal received by the receiver. In the case of applications like sliding doors, the change in signal triggers the self - detecting mechanism. For security alarm systems, the interruption of the beam can trigger an alarm signal that is relayed to the security alarm host.

IV. Installation Instructions

1. To open the IR - 20M, lift the front panel of the photocell.
2. Insert the cables in their housing and fix the base to the wall.
   • If mounting on a wall, drill three 5 ø holes and fit suitable screw anchors.
   • If mounting on metal, drill three 3 ø holes for fitting with self - tapping screws.
3. Make the electrical connections. Power the photocells with a voltage between 12 and 24V DC/AC.
4. If positioning, alignment, and connection are correct, the red LED on the receiver will be off. Each time the ray is interrupted, the red LED switches on.
5. Cover the photocell with the front panel. Insert to the stop and close it.
6. Interrupt the ray several times to check the relay response.
7. Fix the front panels with the provided screws.

V. Applications

1. ​Gate and Door Automation
   • It can work as a body induction device for parking barriers, walking gates, and vehicle gates. It is also suitable for window, door, and passageway anti - burglary detection.
2. ​Security Systems
   • Ideal for incorporation into security setups within educational institutions, commercial complexes, medical facilities, residential premises, etc. The stable detection range ensures accurate detection of intrusions even in outdoor environments.

VI. Conclusion

The JUTAI IR - 20 infrared photo sensor is a high - quality, reliable, and weather - resistant device that offers a wide range of applications in both gate opening mechanisms and security systems. Its advanced features, stable performance, and easy installation make it a great choice for various outdoor detection needs.
