IP67 Rated Photoelectric Barrier for Cold Storage & Industrial High Speed Doors
The JUTAI CL-Series Photoelectric Barrier is a professional infrared safety solution tailored for cold storage environments and industrial high speed doors. It projects an invisible grid of light beams between the emitter and receiver, instantly triggering safety responses (door reversal, equipment stop) upon intrusion—effectively preventing pinching, crushing, or collision accidents. With IP67 protection, wide temperature adaptability, and dual operational modes, it delivers reliable performance in the harsh conditions of cold storage facilities and high-traffic industrial door areas.
-20°C to +60°C (extended range down to -25°C available for cold storage)
Cable Length
Transmitter: 8m; Receiver: 4m
Connector Type
5-pole M8 male connector (transmitter/receiver)
Safety Standards
CE certified, compliant with EN 61496-1/-2 principles
LED Indicators
Transmitter: Steady blue (normal), fast-flashing red (voltage <9V or >28V) Receiver: Steady red (blocked), steady blue (unblocked), flashing blue (misalignment)
Key Advantages
IP67 Rugged Protection
Fully dust-tight and resistant to temporary water immersion, withstanding high-pressure washdowns, dust, and moisture
Ideal for cold storage humidity, industrial dust, and outdoor-installed high speed doors
Cold Storage Adaptability
Stable operation from -20°C to +60°C; optional extended range for extreme cold storage (-25°C)
Resists condensation and freezing, ensuring uninterrupted safety in freezer rooms and refrigerated warehouses
Dual Operational Modes
Standard Protection Mode: Full-area safeguarding—any beam interruption triggers an immediate safety output (perfect for personnel protection)
Blanking (Muting) Mode: Allows safe passage of door structures without false alarms, tailored for high speed door leading edges
High Speed Door Compatibility
≤20ms fast response time matches the operational speed of high speed doors, eliminating safety lags
Multiple length (500mm-2500mm) and beam (8/16) options fit different high speed door sizes
Easy Integration & Diagnostics
Color-coded cables and 5-pole M8 connectors simplify wiring to door controllers or safety relays
Built-in alignment aids and adjustable brackets enable quick installation on various door frames
Visual LED indicators provide at-a-glance status of power, alignment, and blockage
