Infrared Safety Sensor Grid for Roller Shutter Doors with Anti-Pinch Protection
The JUTAI CL20-8L Infrared Safety Sensor Grid is a dedicated anti-pinch solution for roller shutter doors. It forms an 8-beam invisible protective grid between the emitter and receiver, instantly triggering door reversal or stopping when personnel, hands, or objects intrude the detection area. Designed with IP67 protection and rugged aluminum alloy housing, it delivers reliable performance in industrial, commercial, and warehouse environments.

Core Specifications
ParameterSpecification
ModelCL20-8L
Working VoltageDC12-24V
Working CurrentTransmitter: <65mA @DC12V; Receiver: <20mA @DC12V
Output ConfigurationNO/NC relay output (default NO, configurable to NC); COM terminal included
Protection RatingIP67 (dustproof + waterproof)
Housing MaterialAluminum alloy
Operating Range (Emitter to Receiver)1-8m
Maximum Protection Height1729mm
Number of Photocells8 beams
Cable LengthTransmitter: 8m; Receiver: 4m
Connector TypeTransmitter: 5-pole M8 male connector; Receiver: 4-pole M8 male connector
Operating Temperature-20°C ~ +60°C
Key FunctionRoller shutter 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, misalignment)
Key Advantages
  • Targeted Anti-Pinch Protection: Detects hands, limbs, or objects near roller shutter doors, triggering immediate door reversal to prevent pinching accidents. 8-beam full coverage eliminates safety blind spots.
  • Blanking Mode for False Alarm Prevention: Blocks the first channel without triggering safety responses, adapting to roller shutter door gap structures while retaining protection against unintended intrusions.
  • Rugged & Environmentally Adaptable: IP67 protection resists dust, water splashes, and harsh industrial conditions. Wide temperature range (-20°C ~ +60°C) ensures stable operation in various environments.
  • Easy Installation & Operation: Color-coded wiring simplifies connection. Intuitive LED indicators enable quick status checks. Adjustable mounting brackets fit various door frame structures.

ReceiverWhiteCOM (Common Terminal)Matching terminal for NO/NC output
Critical Warning: Do NOT connect NO/NC terminals to the power supply positive terminal—this will damage the optical relay.
Blanking Mode Activation Steps
  1. Power on the sensor grid and confirm correct wiring.
  2. Within 1 minute of power-on, touch the receiver's Green wire to its GND (Black wire) five times.
  3. Observe the receiver's Red light blinking to confirm activation: Yellow wire switches to NC mode, and Blanking Mode is enabled.
Application Scenarios
  • Industrial roller shutter doors (factories, warehouses, logistics centers)
  • Commercial roller shutter doors (retail stores, shopping malls, commercial buildings)
  • Cold storage roller shutter doors (refrigerated warehouses, freezer rooms)
  • Garage roller shutter doors (residential, commercial parking facilities)
Troubleshooting
Fault SymptomsPossible CausesSolutions
Receiver's blue light flashes (power-on)Emitter and receiver misalignmentReadjust positions to ensure parallel alignment
Transmitter's red light flashes fastPower supply voltage <9V or >28VStabilize power supply to meet DC12-24V requirements
Sensor grid works, but door has no anti-pinch actionWiring errorRecheck wiring against the guide; ensure correct connection to door control system
Unable to enter Blanking Mode1. Light leakage during door descent
2. Bottommost beam blocked by debris
3. Door/obstruction fails to meet minimum continuous blocking distance
1. Fix door sealing to prevent light leakage
2. Clear debris blocking the beam
3. Adjust door/obstruction to meet distance requirements
Usage & Maintenance Caveats
  • Keep connecting cables away from high-voltage/high-current conductors to avoid interference or damage.
  • Regularly wipe emitter/receiver lenses with a dry, soft cloth to remove dust, dirt, or condensation.
  • Do not bend, twist, or pull cables forcefully; avoid scratching infrared lenses.
  • Prevent direct sunlight or other infrared light sources from shining on the receiver (avoids false triggers).
  • Ensure the roller shutter door or obstruction used for Blanking Mode meets the minimum continuous blocking distance requirement.
