Photoelectric Safety Device for Automated Doors with Blanking Mode Function
Photoelectric Safety Device for Automated Doors with Blanking Mode Function

The JUTAI CL20-8L Photoelectric Safety Device is a professional protective sensing solution engineered exclusively for automated doors. It forms an invisible 8-beam light grid between the emitter and receiver, instantly triggering safety responses (door reversal, stopping, or alarm) when personnel, objects, or equipment intrude the detection area. With a dedicated Blanking Mode to avoid false alarms, IP67 rugged protection, and user-friendly design, it effectively prevents pinching, crushing, or collision accidents in industrial, commercial, and logistics environments—becoming an indispensable safety component for automated door systems.

Core Specifications
ParameterSpecification

Key FunctionAutomated door anti-pinch protection + Blanking Mode (anti-false alarm)
LED Status IndicatorsTransmitter: Steady blue (normal operation); Fast-flashing red (voltage <9V or >28V)
Receiver: Steady red (object/personnel blocked); Steady blue (no obstruction); Flashing blue (first power-on, emitter-receiver misalignment)
Installation Hole DimensionsRefer to size parameters: 14mm, 80mm, 175mm, 259mm, 29mm, 75mm, 19.7mm, 21.4mm (unit: mm)
Key Functions & Advantages
  • Blanking Mode: Anti-False Alarm for Automated Doors - Specifically designed for automated door gaps where blocking the first channel won't trigger safety responses, adapting to structural characteristics of automated doors
  • Targeted Anti-Pinch Protection - 8-beam light grid covers full door height (1729mm), detecting hands, limbs, or objects to prevent accidents with instant response
  • Rugged & Reliable Performance - IP67 protection withstands dust, water, and temperature extremes from -20°C to +60°C with durable aluminum alloy housing
  • Easy Installation & Intuitive Operation - Color-coded wiring, adjustable mounting, and visual diagnostics simplify setup and maintenance

ReceiverWhiteCOM (Common Terminal)Must connect to door control system's corresponding terminal
Critical Warning: Do NOT connect NO/NC terminals (Green/Yellow wires) to power supply positive terminal—this will permanently damage the optical relay.
Application Scenarios
  • Industrial Automated Doors - Fast doors, roller shutter doors, sectional industrial doors in factories, warehouses, and logistics centers
  • Commercial Automated Doors - Automatic swing doors, sliding doors in shopping malls, office buildings, and retail stores
  • Special Environment Automated Doors - Cold storage automated doors, clean room fast doors, outdoor automated doors resistant to temperature extremes
  • Logistics/Loading Dock Doors - Automated loading dock doors, material transfer area doors for high-frequency operations
Troubleshooting
Fault SymptomsPossible CausesDetailed Solutions
Receiver's blue light flashes continuouslyEmitter and receiver misalignmentCheck parallel installation and adjust positions until blue light stabilizes
Transmitter's red light flashes fastPower supply voltage too low (<9V) or too high (>28V)Test voltage with multimeter and replace with stable DC12-24V adapter
Device works but door has no anti-pinch actionWiring error or door control system issueRecheck wiring and verify door control system recognizes safety signals
Unable to enter Blanking ModeOperation timeout or environmental factorsRestart device and complete activation within 1 minute; check for light interference
