Simple Install Infrared Sensor - JUTAI IR-20 for Door Automation &
Security Systems

The JUTAI IR-20 Infrared Sensor (also called Photocell,
Through-Beam Sensor, or IR Beam Detector) is a user-friendly,
industrial-grade detection solution designed for hassle-free
installation in door automation and security systems. With a
straightforward setup process, 20-meter stable detection range, and
versatile 12-24V AC/DC power compatibility, it creates an invisible
protective beam to prevent door entrapment, detect intrusions, and
enhance access control--ideal for residential garage doors,
commercial sliding doors, office entrances, and perimeter security
worldwide.
Product Overview
As a paired transmitter (TX) and receiver (RX) through-beam sensor,
the IR-20 operates on a simple yet reliable principle: the TX emits
a focused infrared beam that aligns with the RX. When the beam is
interrupted by people, vehicles, or obstacles, the RX's internal
relay triggers instantly--sending a signal to stop a closing door,
activate an alarm, or block unauthorized access.
Built for practicality and durability, the sensor features a
compact, UV-resistant engineering plastic housing with an IP55
protection rating. It's designed to withstand indoor/outdoor
conditions (dust, rain, temperature swings) while keeping
installation steps minimal--no specialized technical skills or
complex tools required.
Core Features & Advantages
Hassle-Free Installation & Setup
- Tool-Minimal Mounting: Supports wall mounting (3x 5mm drill holes with screw anchors) and
metal surface mounting (3x 3mm self-tapping screws)--fits most door
frames, security fences, and building exteriors without custom
modifications.
- Clear Wiring & Labeling: Terminals are prominently marked (TX: 1-2 for power; RX: 1-3 for
power, 4=COM, 5=NC, 6=NO) to eliminate confusion. No complex wiring
diagrams are needed--even first-time installers can complete
connections in minutes.
- Intuitive Alignment: The RX's bright red LED indicator (off when beam is aligned, on
when interrupted) provides real-time feedback. Simply adjust the
TX/RX positions until the LED turns off--no calibration tools or
technical expertise required.
- Snap-On Front Panel: The front panel lifts easily for wiring access and closes securely
with provided screws, streamlining the final setup step and
protecting internal components from dust.
Weatherproof & Reliable Performance
- IP55 Ingress Protection: Resists dust ingress and low-pressure water jets from any
direction, making it suitable for direct outdoor installation
(e.g., garage door exteriors, commercial entryways) without
additional enclosures.
- Wide Temperature Adaptation: Operates stably from -10°C to +60°C, adapting to diverse
climates--from cold winters to hot summer environments--without
performance degradation.
- Anti-Interference Design: Optimized optical filtering minimizes false triggers from ambient
light (sunlight, fluorescent fixtures) and environmental debris,
ensuring consistent performance in busy door automation scenarios.
Universal Compatibility & Practical Functionality
- Flexible Power Input: Works with 12-24V AC/DC (non-polarized) power supplies, seamlessly
integrating with standard door controllers, security alarm panels,
and access control systems--no specialized power adapters needed.
- Versatile Relay Output: Equipped with Common (COM, terminal 4), Normally Closed (NC,
terminal 5), and Normally Open (NO, terminal 6) terminals, ensuring
compatibility with all major door automation and security hardware.
- Low Power Consumption: TX max operating current ≤25mA and RX max operating current ≤35mA,
supporting energy-efficient 24/7 operation without excessive power
usage.

Step-by-Step Installation Guide
1. Prepare the Mounting Site: Choose a location with a clear line of sight between the TX and RX
(avoid obstacles like bushes or door hardware). For walls, drill 3x
5mm holes and insert screw anchors; for metal surfaces, drill 3x
3mm holes for self-tapping screws.
2. Access Wiring Terminals: Lift the front panel of both the TX and RX to expose the terminal
blocks--no tools required for panel removal.
3. Connect Power & Controls: Wire 12-24V AC/DC power to TX terminals 1 and 2. Connect the same
power supply to RX terminals 1, 2, or 3 (matching the voltage
rating). Link RX terminals 4 (COM), 5 (NC), and 6 (NO) to your door
controller, alarm panel, or access system.
4. Align the Sensor Pair: Adjust the positions of the TX and RX until the RX's red LED turns
off--this indicates a stable beam connection.
5. Secure & Test: Close the front panels and fasten them with the provided screws.
Test by interrupting the beam--verify the RX LED turns on and the
connected system (door controller/alarm) responds correctly.
Typical Applications
- Residential Garage Doors: Prevents entrapment of people, pets, or objects during closure,
enhancing home safety.
- Commercial Sliding Doors: Ensures safe operation in malls, retail stores, and office
buildings--stopping doors from closing on pedestrians.
- Industrial Gate Automation: Detects vehicles or obstacles in the path of industrial sliding
gates or parking barriers.
- Perimeter Security: Creates invisible beam barriers for backyard fences, office
perimeters, or restricted access zones--triggering alarms for
unauthorized entry.
- Public Facility Entrances: Enhances safety for automatic doors in hospitals, schools, and
train stations, where ease of installation and reliability are
critical.
