12-24V AC/DC Industrial & Commercial Infrared Photocell – Reliable Perimeter Security & Safety Detection

Product Overview

Core Features & Advantages

1. Industrial-Grade Durability & Weather Resistance

• 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 (e.g., warehouses with dust or moisture).
• 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, commercial security panels, and access control systems.
• 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.

2. 30-Meter Long-Range & Anti-Interference Detection

• Extended Detection Range: Delivers a stable, focused infrared beam over 30 meters (indoor/outdoor), covering wide openings (industrial gates, warehouse loading bays) and large commercial spaces (shopping mall atriums, parking lot perimeters) without signal degradation.
• Anti-Environmental Interference: Optimized optical technology minimizes false triggers caused by ambient light (sunlight, fluorescent fixtures), rain, or dust—critical for industrial environments with variable lighting and commercial areas with high foot traffic.
• Intuitive Status Feedback: The RX features a bright red LED indicator: off when the beam is unobstructed (normal operation) and on when interrupted. This allows technicians to quickly align the sensor during installation and troubleshoot issues in real time.

3. Universal Integration & Hassle-Free Installation

• Versatile Relay Output: Equipped with a Single Pole Double Throw (SPDT) relay, including Common (COM, terminal 4), Normally Closed (NC, terminal 5), and Normally Open (NO, terminal 6) terminals. This universal design ensures compatibility with any industrial machinery safety interlock, commercial alarm system, or automatic door/gate controller.
• Dual Mounting Solutions: Supports wall mounting (3x 5mm drill holes with screw anchors) for commercial buildings and metal surface mounting (3x 3mm self-tapping screws) for industrial equipment or metal structures, adapting to diverse installation scenarios.
• Simplified Wiring & Labeling: Clear terminal markings (TX: 1-2 for power; RX: 1-3 for power, 4-6 for relay output) reduce installation errors, saving time for technicians in both industrial and commercial settings.

4. Safety-Centric Design for Industrial & Commercial Use

• Perimeter Intrusion Prevention: Creates an invisible security barrier for industrial facility perimeters, commercial property boundaries, or restricted areas (e.g., server rooms, inventory storage), triggering alarms when breached.
• Machinery Safety Interlock: Acts as a safety sensor for industrial machinery (conveyors, packaging lines) and commercial equipment (automatic doors, parking barriers), preventing entrapment or collision by stopping operation when obstacles are detected.
• Low Power Consumption: TX max operating current ≤25mA and RX max operating current ≤35mA, ensuring energy efficiency for 24/7 operation in industrial plants and commercial buildings.

Technical Specifications

Typical Applications

Industrial Security & Safety

• 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, automated storage and retrieval systems (ASRS), and packaging machinery—stopping operation when workers or obstacles are in the danger zone.
• Industrial Gate Automation: Detection for large factory gates or vehicle access points—preventing gate closure on vehicles or equipment.

Commercial Security & Access Control

• 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—enhancing tenant and visitor safety.
• Hospital & Public Facility Security: Non-intrusive detection for emergency exits, medical supply rooms, or high-security areas (e.g., data centers in office buildings).

Installation & Wiring Guide

1. Mounting Preparation: Select a location with an unobstructed line of sight between the TX and RX. For wall mounting (commercial buildings), drill 3x 5mm holes and install screw anchors; for metal surfaces (industrial equipment), 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 (matching the voltage rating).
   • 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 (alarm, door controller, machinery) responds correctly.
