Weatherproof IR Beam Sensor – Professional Anti-Burglar &
Access Control Solution
The JUTAI IR-20M Weatherproof IR Beam Sensor (also named Infrared
Photocell, Through-Beam Sensor, or Anti-Burglar IR Detector) is a
rugged, security-focused detection device engineered exclusively
for anti-burglar systems and access control applications. With an
IP55 weatherproof rating, stable 20-meter detection range, and
versatile 12-24V AC/DC power compatibility, it creates an
invisible, reliable security barrier to deter intrusions, manage
access, and protect property—making it ideal for residential
perimeters, commercial buildings, industrial facilities, and
restricted access zones worldwide.
Product Overview
As a professional through-beam sensor pairing a precision
transmitter (TX) and receiver (RX), the IR-20M operates on a
time-tested principle: the TX emits a focused infrared beam that
locks onto the RX to form a continuous detection path. When an
intruder, vehicle, or any obstacle breaks the beam—whether during
daytime or nighttime—the RX’s internal changeover relay triggers
instantly. This sends a rapid signal to your anti-burglar alarm
system (activating sirens or alerts) or access control panel
(blocking unauthorized entry or stopping automated gates), ensuring
proactive security responses.
Built to withstand outdoor elements and high-traffic security
scenarios, the IR-20M features a UV-resistant engineering plastic
housing with a tight rubberized seal. It’s designed for 24/7
uninterrupted operation, resisting dust, rain, temperature
fluctuations, and minor vibrations—critical for long-term
anti-burglar and access control reliability.
Core Features & Advantages
1. IP55 Weatherproof & Rugged Construction
- IP55 Ingress Protection: Fully shields against dust ingress and low-pressure water jets
from any direction, enabling direct outdoor installation for
perimeter anti-burglar barriers without additional enclosures.
- UV & Corrosion Resistance: The durable housing resists sun-induced degradation and harsh
weather, maintaining performance in rain, snow, or high-humidity
environments—essential for year-round security.
- Wide Temperature Adaptation: Functions reliably from -10°C to +60°C, adapting to diverse
climates (from cold residential areas to hot commercial parking
lots).
2. 20-Meter Stable Anti-Burglar Detection
- Long-Range Security Coverage: Delivers a focused, consistent infrared beam over 20 meters
(indoor/outdoor), covering wide gaps (yard fences, building
entrances, or industrial gate openings) with no signal loss.
- Anti-Interference Technology: Optimized optical design minimizes false alarms caused by ambient
light (direct sunlight, streetlights), rain, or dust—eliminating
unnecessary alerts and ensuring trustworthy anti-burglar
performance.
- Intuitive Status Indicator: The RX features a bright red LED: off when the beam is
unobstructed (normal security status) and on when interrupted. This
allows quick alignment during installation and instant
troubleshooting for security teams.
3. Universal Integration for Anti-Burglar & Access Control
- Versatile Power Compatibility: Operates on 12-24V AC/DC (non-polarized), seamlessly integrating
with standard anti-burglar alarm panels, access control systems,
automatic gate controllers, and PLCs—no specialized power supplies
needed.
- SPDT 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 security and access control hardware.
- Low Power Consumption: TX max operating current ≤25mA and RX max operating current
≤35mA, supporting energy-efficient 24/7 security monitoring without
high power costs.
4. Easy Installation & Security-Focused Design
- Dual Mounting Options: Supports wall mounting (3x 5mm drill holes with screw anchors)
for residential/commercial exteriors and metal surface mounting (3x
3mm self-tapping screws) for industrial gates or metal
fences—adapting to diverse security setups.
- Simplified Wiring & Labeling: Clear terminal markings (TX: 1-2 for power; RX: 1-3 for power,
4-6 for relay output) reduce installation errors, allowing security
technicians to set up quickly.
- Tamper-Resistant Assembly: The front panel secures with screws, preventing unauthorized
tampering—critical for maintaining the integrity of anti-burglar
systems.

Typical Applications
Anti-Burglar Systems
- Residential Perimeter Protection: Invisible beam barriers for yard fences, garden gates, or
windows—triggering alarms for unauthorized entry.
- Commercial Building Security: After-hours protection for storefronts, back-of-house entrances,
inventory rooms, or office perimeters.
- Industrial Facility Anti-Burglar: Detection for warehouse fences, loading dock entrances, or
equipment storage areas—deterring theft or vandalism.
Access Control Systems
- Automated Gate Access: Safety detection for residential/commercial garage doors,
industrial sliding gates, or parking barriers—preventing closure on
vehicles/pedestrians and blocking unauthorized access.
- Restricted Area Access: Invisible beams for server rooms, data centers, or high-security
offices—triggering alerts if unauthorized personnel breach the
zone.
- Public Facility Access: Security for hospital restricted areas, school perimeters, or
government building entrances—enhancing controlled access.
Installation & Wiring Guide
- Mounting Preparation: Select a location with an unobstructed line of sight between TX
and RX (avoid bushes, moving objects, or direct sunlight on RX).
For walls, drill 3x 5mm holes and install screw anchors; for metal
surfaces, drill 3x 3mm holes for self-tapping screws.
- Panel & Wiring Setup: Lift the front panel of both TX and RX, route cables through the
housing, and connect as follows:
- Connect 12-24V AC/DC power to TX terminals 1 and 2.
- Connect the same power supply to RX terminals 1, 2, or 3 (matching
voltage).
- Wire RX terminals 4 (COM), 5 (NC), and 6 (NO) to your anti-burglar
alarm panel or access control system.
- Alignment: Adjust TX and RX positions until the RX’s red LED turns off
(indicating a stable beam connection). Fine-tune for long-range
reliability.
- Final Security Test: Secure front panels with provided screws. Test by interrupting
the beam—verify the RX LED turns on and the connected system
(alarm, gate controller) responds instantly.
