Description

The StanBon STD20-20NC Safety Light Curtain Sensor utilizes an array of synchronized infrared LED transmitters and receivers to create an invisible protective curtain. When any beam is interrupted, the sensor’s control unit triggers a safety output signal (typically via OSSD outputs) to halt machinery or lock access, ensuring compliance with safety standards.

Engineered for reliability in industrial settings, the unit features a durable enclosure designed to resist vibration and environmental contaminants. Its compact form factor and standardized mounting points allow for straightforward integration into machine safety systems, production lines, and automated access control points.

Key Features

  • High-density 20-beam infrared array for reliable intrusion detection.
  • Precision 20mm beam pitch minimizes undetected access risks.
  • Wide operating voltage range (12-24V DC) ensures compatibility with common industrial power supplies.
  • Durable, industrial-grade housing for long-term operation in challenging environments.
  • Designed for easy integration with safety relays, PLCs, and machine control systems.
  • Provides a defined 380mm detection zone suitable for a variety of guarding applications.

Applications

  • Machine guarding and perimeter safety on press brakes, robotic cells, and automated assembly lines.
  • Access control and personnel detection at hazardous entry points in manufacturing facilities.
  • Material handling system safety to detect obstructions in conveyor paths.
  • Packaging and palletizing equipment safety interlocks.

Frequently Asked Questions

What is the operating voltage range for the STD20-20NC light curtain?

The STD20-20NC operates on a wide-range DC input of 12 to 24 volts. This flexibility allows it to be powered by standard industrial 24V DC power supplies or lower-voltage control circuits, ensuring easy integration into existing plant electrical systems.

How does the 20mm beam pitch affect safety performance?

A 20mm beam pitch means the infrared detection beams are spaced 20mm apart. This fine resolution helps prevent smaller objects, like fingers or tools, from passing through the curtain undetected, making it suitable for applications requiring higher safety integrity levels (SIL) or Performance Level (PL) ratings.

What type of output signal does this light curtain provide for machine control?

While specific output details are model-dependent, safety light curtains like the STD20-20NC typically provide dual solid-state safety outputs (OSSDs) that switch to a safe state when a beam is broken. These outputs are designed to connect directly to safety relays, PLC safety inputs, or the enabling circuit of a machine's controller to initiate an immediate stop.
