Product Description

Lifecycle Status:

The Sick L4000 Systems L40S-21MA1A Safety Light-Beam Sensor is designed to provide robust and reliable safety solutions in industrial environments. Utilizing a visible red LED light source, this sensor offers a scanning range of up to 16 meters with a detection capability of 30 mm. The axial optical axis ensures precise alignment and accurate detection.

Engineered to meet stringent safety standards, the L40S-21MA1A is classified as a Type 4 device (IEC 61496-1) and achieves a SIL 3 safety integrity level (IEC 61508). It also meets Category 4 and PL e (EN ISO 13849) requirements, ensuring maximum protection in critical applications. The sensor's response time is a swift 0.4 ms, making it ideal for high-speed operations.

The sensor features a robust nickel-plated brass housing with an IP67 enclosure rating, ensuring durability and resistance to harsh environmental conditions. It operates reliably within a temperature range of -20°C to +55°C and can withstand vibrations and shocks as per IEC standards.

With a male M12, 4-pin connector and LED display elements, the L40S-21MA1A is easy to integrate and monitor. It is powered by a 24 V DC supply and consumes less than 60 mA, making it energy-efficient. The sensor is compliant with multiple international standards, including EU, UK, ACMA, Moroccan, and China-RoHS declarations of conformity.

This sensor is ideal for applications requiring high safety levels, such as in manufacturing, automation, and machinery protection. Its long...
