The STD20-28NC Light Curtain Sensor operates on the principle of infrared beam interruption. An array of 28 synchronized infrared LEDs and corresponding phototransistor receivers creates a protective curtain. When any single beam is broken, the sensor’s output changes state, signaling a control system (e.g., PLC or safety relay) to halt machinery or trigger an alarm. This provides a non-contact safety solution superior to physical barriers or mats.
Engineered for industrial durability, the sensor’s housing protects internal electronics from dust, vibration, and typical ambient light interference. Its 12-24V DC operating range allows direct integration with standard industrial power supplies and logic controllers, making it a reliable component for Category 2 or 3 safety circuits as per relevant standards.
