Description

The Pro-Range GB20-T16 operates on the principle of infrared beam interruption. The emitter unit projects 16 parallel infrared beams (950nm wavelength) across a 300mm height. The receiver unit detects these beams, and any object interrupting one or more beams triggers a safety output signal within 15 milliseconds. This system is engineered for high immunity to ambient light, tolerating up to 10,000 Lux, ensuring stable operation in brightly lit industrial settings.

Built for harsh industrial environments, the sensor features an IP64 ingress protection rating and a housing constructed from an aluminum alloy cover, ABS industrial plastic, and cold-rolled steel sheets. It operates reliably across a temperature range of -10°C to 55°C and withstands significant shock and vibration. The integrated output can handle up to 300mA, making it suitable for directly interfacing with machine safety relays or PLCs to initiate an immediate stop command.

Key Features

  • High-resolution 16-beam array with 20mm pitch for precise object detection.
  • Wide operating range from 0.3M to 10m with adjustable sensitivity.
  • Fast 15ms response time ensures immediate machine halt for enhanced safety.
  • Durable IP64-rated construction with aluminum alloy and industrial-grade plastics.
  • High immunity to ambient light interference (up to 10,000 Lux).
  • Dual-voltage DC input (12V/24V) simplifies integration into existing control panels.
  • Includes pre-wired emitter and receiver units for quick installation.
  • Certified for robust performance with high shock and vibration resistance.

Applications

  • Machine guarding on press brakes, stamping presses, and robotic work cells.
  • Access control and personnel safety zones around automated packaging machinery.
  • Material handling systems, such as conveyor belt entry/exit point protection.
  • Safety perimeter establishment for CNC machining centers and industrial lathes.
  • Hazard zone monitoring in woodworking, plastic molding, and automotive assembly lines.

Frequently Asked Questions

What is the purpose of the 20mm beam pitch on the GB20-T16?

The 20mm beam pitch defines the vertical spacing between each of the 16 infrared beams. This resolution determines the minimum size of an object that can be reliably detected. With this pitch, the system can detect objects as small as 32mm in diameter, providing a fine protective grid for enhanced safety around machinery.

How do I wire and power the GB20-T16 light curtain?

The GB20-T16 operates on a 12V or 24V DC power supply. Connect the positive and negative leads from your DC source to the corresponding terminals on both the emitter and receiver units, ensuring correct polarity. The output signal wires are then connected to your machine's safety relay or PLC input to trigger a stop command upon beam interruption.

What does the IP64 rating mean for installation?

The IP64 rating indicates the sensor is dust-tight (6) and protected against water splashes from any direction (4). This allows for safe installation in most industrial environments where dust, debris, or incidental coolant splashes are present. However, it is not submersible or suitable for high-pressure water jet cleaning.

Can this sensor be used outdoors or in direct sunlight?

While the sensor has high ambient light immunity (up to 10,000 Lux), prolonged direct sunlight can exceed this threshold and potentially cause interference. For reliable outdoor use, it is recommended to install the sensor in a shaded location or use protective shrouds to shield the optical windows from direct sun exposure.

What is included in the package for installation?

The package includes one emitter unit and one receiver unit, each with pre-attached cables. The emitter cable is 0.3M + 3M long, and the receiver cable is 0.3M + 7m long, providing flexibility for mounting at a distance from the control cabinet. No additional mounting brackets are included; these must be sourced separately based on your specific installation requirements.

Package Includes

  • 1 x Pro-Range GB20-T16 Light Curtain Sensor (Emitter Unit)
  • 1 x Pro-Range GB20-T16 Light Curtain Sensor (Receiver Unit)
