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 (Simple Install Focused)
1. 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.
2. 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.
3. 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
- 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.
- Access Wiring Terminals: Lift the front panel of both the TX and RX to expose the terminal
blocks—no tools required for panel removal.
- 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.
- 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.
- 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.
