Description

The Pro-Range GB40-T24 Light Curtain Sensor is an optoelectronic safety device that establishes an invisible protective field around hazardous machinery. Utilizing 24 synchronized infrared beams at a 950nm wavelength, it monitors for beam interruption with high resolution (Φ52mm) and a horizontal aperture of ±5°. Upon detection, it outputs a signal within 10ms to initiate a safety stop function, preventing accidents.

Engineered for harsh industrial environments, the sensor features an IP64 protection rating, high immunity to ambient light (up to 10,000 Lux), and operates reliably across a temperature range of -10°C to 55°C. Its durable construction combines an aluminum alloy cover, ABS industrial plastic, and cold-rolled steel sheets, ensuring longevity and resistance to mechanical shock up to 500 m/s² (50G).

Key Features

  • High-resolution 24-beam infrared array with 40mm pitch for precise intrusion detection.
  • Extended operating range from 0.3 to 10 meters with consistent beam alignment.
  • Ultra-fast safety response time of 10 milliseconds for immediate machine halt.
  • Dual-voltage DC input (12V/24V) with low quiescent current (<110mA) for flexible integration.
  • IP64-rated enclosure provides protection against dust and water splashes.
  • Superior ambient light immunity (10,000 Lux) for stable operation under bright factory lighting.
  • Robust mechanical design with aluminum alloy and steel components for impact resistance.
  • Integrated cables (Emitter: 3M, Receiver: 7m) with connectors for simplified installation.

Applications

  • Machine guarding on press brakes, stamping presses, and robotic work cells.
  • Access control and perimeter safety for automated assembly lines and conveyor systems.
  • Personnel protection in material handling, packaging, and palletizing machinery.
  • Safety interlocking for industrial doors, gates, and hazardous area access points.
  • Integration into PLC-controlled safety systems for ISO 13849 compliant risk reduction.

Frequently Asked Questions

What is the operating voltage for the Pro-Range GB40-T24 light curtain?

The Pro-Range GB40-T24 light curtain sensor is designed for dual-voltage operation, accepting either 12V DC or 24V DC power input. This flexibility allows for integration into a wide range of industrial control panels and power systems. Ensure your power supply can deliver the required current, as the quiescent draw is under 110mA.

How do I mount and align the emitter and receiver units?

Mount the emitter and receiver units on stable surfaces opposite each other, ensuring they are parallel and within the 0.3M to 10m operating range. The units have a horizontal alignment tolerance of ±5° at distances of 3 meters or more. Use the provided mounting holes and ensure the 920mm detection height covers the intended hazard zone.

What output signal does this light curtain provide when a beam is broken?

When any of the 24 infrared beams is interrupted, the sensor's safety output circuit activates. It provides a solid-state output capable of sinking or sourcing up to 300mA, which is typically used to switch the control input of a safety relay or PLC safety module to initiate a machine stop.

Is this sensor suitable for outdoor use or environments with high ambient light?

With an IP64 rating, it is protected against dust and water splashes, making it suitable for many indoor industrial environments but not for continuous outdoor exposure to rain. Its high ambient light immunity (10,000 Lux) ensures stable operation under bright factory lighting, including direct incandescent light up to 3,000 Lux.

What is the response time, and why is it critical for safety applications?

The Pro-Range GB40-T24 has an exceptionally fast response time of less than 10 milliseconds from beam interruption to output signal change. This speed is critical in safety applications to ensure that a machine's hazardous motion is stopped before a person can reach the danger zone, helping to achieve required safety performance levels (PL) per ISO 13849.
