IP65 Rated 12-24V AC DC Infrared Photocell Sensor Perfect for Industrial

The JUTAI IR-20 Infrared Photocell (also known as IR Beam Sensor, Through-Beam Sensor, or Safety Photocell) is a rugged, industrial-grade detection solution engineered for industrial and commercial security scenarios. Operating on a versatile 12-24V AC/DC power supply, it delivers a stable 30-meter invisible infrared beam to detect obstacles, intrusions, and hazards—making it an essential component for perimeter protection, automated access control, and safety interlocks in factories, warehouses, shopping malls, and commercial complexes worldwide.

As a through-beam sensor pairing a precision transmitter (TX) and receiver (RX), the IR-20 works on a straightforward yet highly reliable principle: the TX emits a focused infrared beam that aligns with the RX. When the beam is interrupted by any object—whether an intruder, vehicle, equipment, or debris—the RX's internal SPDT relay triggers instantaneously. This sends a signal to your security system, access controller, or machinery to activate alarms, stop operation, or block access, ensuring rapid response to potential risks.

Crafted with industrial durability in mind, the IR-20 features a UV-resistant engineering plastic housing with a rubberized seal, designed to withstand the rigors of industrial environments (dust, vibrations, temperature swings) and commercial high-traffic areas. It's built for 24/7 continuous duty, providing consistent performance where security and safety cannot be compromised.

• IP55 Ingress Protection: Effectively shields against dust ingress and low-pressure water jets from any direction, enabling direct outdoor installation for perimeter security and indoor use in harsh industrial settings
• Wide Voltage Flexibility: Operates seamlessly on 12-24V AC/DC (non-polarized), eliminating the need for specialized power supplies and integrating effortlessly with standard industrial PLCs and commercial security panels
• Temperature Resilience: Functions reliably from -10°C to +60°C, adapting to extreme climate conditions from cold industrial warehouses to hot outdoor commercial parking areas

• Extended Detection Range: Delivers a stable, focused infrared beam over 30 meters (indoor/outdoor), covering wide openings and large commercial spaces without signal degradation
• Anti-Environmental Interference: Optimized optical technology minimizes false triggers caused by ambient light, rain, or dust—critical for industrial environments with variable lighting
• Intuitive Status Feedback: The RX features a bright red LED indicator: off when the beam is unobstructed and on when interrupted for easy installation and troubleshooting

• Versatile Relay Output: Equipped with a Single Pole Double Throw (SPDT) relay with Common (COM), Normally Closed (NC), and Normally Open (NO) terminals for universal compatibility
• Dual Mounting Solutions: Supports wall mounting and metal surface mounting, adapting to diverse installation scenarios in commercial and industrial settings
• Simplified Wiring & Labeling: Clear terminal markings reduce installation errors, saving time for technicians in both industrial and commercial settings

• Factory Perimeter Protection: Invisible beam barriers for facility walls, fences, or loading dock entrances—triggering alarms for unauthorized access
• Warehouse Safety Interlocks: Safety sensors for conveyor systems and automated storage systems—stopping operation when workers or obstacles are in danger zones
• Industrial Gate Automation: Detection for large factory gates or vehicle access points—preventing gate closure on vehicles or equipment

• Shopping Mall & Retail Security: Perimeter protection for back-of-house areas, inventory rooms, or storefront entrances after hours
• Parking Lot & Garage Safety: Obstacle detection for automatic parking barriers and garage doors—preventing collisions with vehicles or pedestrians
• Office Building & Commercial Complex Access: Safety sensors for automatic sliding doors, restricted area entrances, and elevator lobbies
• Hospital & Public Facility Security: Non-intrusive detection for emergency exits, medical supply rooms, or high-security areas

1. Mounting Preparation: Select a location with an unobstructed line of sight between the TX and RX. For wall mounting, drill 3x 5mm holes and install screw anchors; for metal surfaces, drill 3x 3mm holes for self-tapping screws
2. Wiring Connection: Connect 12-24V AC/DC power to TX terminals 1 and 2. Connect the same power supply to RX terminals 1, 2, or 3. Wire RX terminals 4 (COM), 5 (NC), and 6 (NO) to your security panel, PLC, or access controller
3. Alignment: Adjust the TX and RX positions until the RX's red LED turns off, indicating a stable beam connection. Use the LED feedback to fine-tune alignment for long-range detection
4. Final Testing: Secure the front panels with the provided screws. Test the sensor by interrupting the beam—verify the RX LED turns on and the connected system responds correctly
