Description

The StanBon STD20-24NC Safety Light Curtain Sensor utilizes an array of 24 synchronized infrared beams to create an invisible protective screen. When any beam is interrupted, the sensor outputs a signal to halt machinery or trigger an alarm, ensuring personnel safety around automated equipment. Its design is optimized for reliable performance in industrial settings with varying ambient light conditions.

Engineered for easy integration into safety control systems, this light curtain features a wide operating voltage and a compact form factor. The 20mm beam pitch provides a fine resolution, making it effective at detecting fingers, hands, or small tools, thereby preventing access to dangerous zones in robotic cells, press brakes, and automated assembly lines.

Key Features

  • High-Resolution Detection: 24-beam array with a tight 20mm pitch for precise intrusion monitoring and small object detection.
  • Industrial-Grade Durability: Housing constructed to withstand vibration, dust, and typical factory environmental stressors.
  • Flexible Power Supply: Compatible with standard 12-24V DC industrial control voltages, simplifying wiring and integration.
  • Easy Installation & Alignment: Compact design with standard mounting holes for straightforward setup on machinery frames and enclosures.
  • Reliable Safety Function: Provides a failsafe monitored output (typically NPN or PNP) for direct connection to safety relays or PLC safety inputs.

Applications

  • Personnel safety guarding on robotic welding cells and assembly stations.
  • Access point monitoring for press brakes, stamping machines, and injection molding equipment.
  • Intrusion detection in automated material handling and packaging systems.
  • Perimeter safeguarding for CNC machining centers and industrial ovens.
  • Object presence verification in conveyor line entry and exit points.

Frequently Asked Questions

What is the output signal type of the STD20-24NC light curtain?

The STD20-24NC typically provides a safety-rated solid-state output, configurable as either a sinking (NPN) or sourcing (PNP) signal. This output is designed to connect directly to a safety relay, programmable logic controller (PLC) safety input, or the emergency stop circuit of machinery to initiate a protective stop when a beam is broken.

How do I align the emitter and receiver units during installation?

Alignment is critical for reliable operation. Mount the emitter and receiver units on stable surfaces facing each other, ensuring they are parallel and within the specified maximum operating distance. Most units have alignment indicator LEDs that signal successful beam synchronization when all infrared beams are properly received without obstruction.

Can this light curtain detect transparent objects like glass or clear plastic?

Standard infrared light curtains can struggle with highly transparent materials, as the infrared light may pass through with minimal attenuation. For applications requiring detection of glass or clear plastics, specialized light curtains with different wavelengths or sensing technologies, or the use of opaque markers on the objects, may be necessary.

What is the typical response time, and how does it affect safety?

The response time is typically under 15 milliseconds from beam interruption to output signal change. This fast reaction is essential for safety applications to ensure a machine can be stopped before a person's limb reaches the hazard point, complying with safety standards like ISO 13855 that define minimum safety distances based on system stopping performance.
