Description

The STM40-24NC operates on the principle of infrared light beam interruption. When an object breaks one or more of its 24 synchronized beams, the sensor’s control unit triggers a safety output signal (typically an OSSD or relay) to halt machinery or initiate a safety protocol. This design ensures fail-safe monitoring of hazardous areas.

Engineered for industrial environments, the sensor is built to withstand typical operational stresses including vibration and electrical noise. Its 12-24V DC input range allows for direct connection to common PLC (Programmable Logic Controller) and safety relay systems, making it a versatile component for enhancing workplace safety and automation efficiency.

Key Features

  • High-Density Beam Array: 24 independent infrared beams create a dense detection field for reliable obstruction sensing.
  • Precise 40mm Beam Pitch: Ensures small objects or body parts are detected, meeting common safety standards for machinery guarding.
  • Industrial-Grade Power Supply: 12-24V DC wide-range input ensures compatibility with standard control cabinet voltages.
  • Compact and Durable Housing: Designed for easy mounting on machine frames, gates, or production lines with robust construction.
  • Safety-Focused Output: Typically provides safety-rated outputs (e.g., OSSD) for direct connection to machine safety circuits.
  • Optimized Detection Height: 920mm coverage is suitable for a wide range of access point and perimeter guarding applications.

Applications

  • Machine guarding and perimeter safety on presses, robotic cells, and assembly lines.
  • Access point monitoring for automated doors, gates, and material handling systems.
  • Personnel detection in hazardous zones within packaging, woodworking, and metalworking facilities.
  • Integration into safety interlock systems for compliance with industrial safety standards (e.g., ISO 13855).

Frequently Asked Questions

What is the operating voltage range for the STM40-24NC light curtain?

The STM40-24NC operates on a 12-24V DC power supply. This wide input range allows for flexible integration with standard industrial control panels and PLC power sources. Ensure your power supply is stable and within this range for reliable operation.

What does the '40mm beam pitch' specification mean?

The 40mm beam pitch refers to the center-to-center distance between adjacent infrared beams in the curtain. This spacing determines the minimum size of an object that can reliably break the beam and trigger the safety output. A 40mm pitch is common for detecting fingers and hands to meet machinery safety standards.

How do I install and align the STM40-24NC light curtain sensor?

Installation involves securely mounting the emitter and receiver units opposite each other, ensuring they are parallel and within the specified alignment tolerance. The 920mm detection height defines the vertical coverage. Proper alignment is critical; most units have alignment indicators or LEDs to assist in setup for optimal beam reception.

What type of output signal does this light curtain provide?

This safety light curtain typically provides safety-rated outputs such as OSSDs (Output Signal Switching Devices) or relay contacts. These outputs are designed to connect directly to a machine's safety controller or emergency stop circuit, causing an immediate halt when a beam is interrupted, ensuring fail-safe operation.
