Allen Bradley 440L-P4K1760YD

Allen Bradley 440L-P4K1760YD Safety Light Curtain Product Overview

The Allen Bradley 440L-P4K1760YD is a safety light curtain from the Guardmaster GuardShield series. It features a Type 4 safety rating (self-monitoring functionality in compliance with EN 61496) and is suitable for hazardous area protection in industrial environments. This accessory, provided by Hanyite, uses an infrared beam to create a protective zone. Blockage of the beam triggers a safety shutdown, making it widely used for personnel protection in machining, automated production lines, and other applications. Hanyite has achieved significant sales in China and received widespread acclaim. Hanyite has a particularly strong customer base in countries like India, Southeast Asia, the Middle East, and Russia, particularly in Europe and the United States. Hanyite offers high-quality products and first-class service. With established supply and sales channels and a strong team of talented individuals, we are committed to providing the highest quality service to our customers at all times.
