Description

The GB40-T12 operates on the principle of infrared beam interruption. The emitter projects 12 parallel beams at a 40mm pitch, which are received by the paired receiver unit. Any object interrupting one or more beams triggers a safety output signal within 10 milliseconds, designed to stop hazardous machinery. It features high ambient light immunity (up to 10,000 Lux) for reliable operation in challenging industrial environments.

Engineered for durability, the sensor’s housing combines an aluminum alloy cover with ABS industrial plastic and cold-rolled steel internal components, providing shock resistance up to 500 m/s² (50G). Its IP64 rating ensures protection against dust ingress and water splashes, supporting operation in temperatures from -10°C to 55°C. The integrated cables simplify connection to machine safety interfaces.

Key Features

  • High-Resolution Safety Field: 12 infrared beams with a 40mm pitch create a precise 440mm high detection zone for personnel and object protection.
  • Fast-Acting Safety Output: ≤10 ms response time ensures immediate machine halt upon beam interruption, meeting safety standards.
  • Industrial-Grade Construction: IP64-rated enclosure with aluminum alloy and ABS plastic provides durability in harsh factory conditions.
  • Wide Operating Voltage: Compatible with standard 12V or 24V DC control panels, offering flexible power integration.
  • High Noise Immunity: Resists ambient light interference up to 10,000 Lux and incandescent light up to 3,000 Lux.
  • Robust Mechanical Design: Withstands shocks of 500 m/s² (50G) and operates across a -10°C to 55°C temperature range.
  • Integrated Connection Cables: Includes pre-wired emitter (3.3M total) and receiver (7.3M total) cables for straightforward installation.

Applications

  • Machine guarding on press brakes, stamping presses, and robotic work cells to prevent operator injury.
  • Access control and presence detection at the entrance of automated assembly lines or hazardous zones.
  • Safety perimeter establishment around CNC machining centers, packaging machinery, and palletizers.
  • Object detection and anti-collision systems for material handling equipment like automated guided vehicles (AGVs).
  • Personnel protection in areas with rotating machinery, such as conveyor belt junctions and automated warehouses.

Frequently Asked Questions

What is the operating voltage for the GB40-T12 light curtain?

The GB40-T12 is designed for flexible integration into industrial control panels, operating on a wide range of 12V or 24V DC power supplies. Ensure your power source can provide the required quiescent current (≤100 mA) and is stable within the sensor's specified tolerance.

How do I wire the output signal from this sensor to my machine's safety system?

The sensor provides a solid-state safety output signal capable of sinking up to 300 mA. Typically, you wire this output in series with your machine's emergency stop circuit or directly to a safety relay input. Refer to the included emitter and receiver cables for power (V+, GND) and output signal connections.

What does the 40mm 'pitch' specification mean for installation?

The 40mm pitch refers to the center-to-center spacing between each of the 12 infrared beams. This defines the minimum size of an object that can be reliably detected. An object smaller than 40mm might pass through without interrupting a beam, so ensure the pitch matches your required detection resolution for personnel or object safety.

Can this sensor be used outdoors or in wet environments?

With an IP64 rating, the sensor is protected against dust ingress and water splashes from any direction, making it suitable for most indoor industrial environments. It is not submersible or rated for prolonged exposure to running water or heavy rain, so outdoor use requires additional protective housing.

What is the maximum cable length between the emitter and receiver units?

The effective detection range is 0.3 to 10 meters. This distance is the maximum recommended separation between the aligned emitter and receiver units for reliable beam reception. The sensor comes with integrated cables (emitter: 3.3M, receiver: 7.3M); extending these cables is not advised as it can affect signal integrity and safety compliance.
