Description
Overview
The BEAM SAFETY DEVICE TRANSMITTER MULTIPLE LIGHT-MLD500-T3L forms part of the MLD 500 safety light curtain series, engineered for reliable access protection in industrial environments. Designed as a three-beam transmitter, it provides dependable monitoring with a 400 mm beam spacing, making it suitable for applications where operators and machinery must coexist safely. Operating on a 24 VDC supply, this device delivers consistent, interference-resistant infrared LED performance with a wavelength of 850 nm. With no software or DIP-switch configuration required, it offers straightforward integration into existing systems.
Design and Features
This transmitter uses pulsed infrared LEDs to maintain stable detection even in demanding conditions. It includes an integrated laser alignment aid, allowing fast and accurate installation, reducing setup time on-site. The unit communicates visually through three onboard LEDs, giving clear status information at a glance. With its rugged IP67 housing, it withstands dust, moisture, and harsh industrial environments without compromising performance.
The MLD500-T3L is compatible with a wide range of receivers, including MLD510, MLD520, MLD530, and MLD535 variants. This ensures flexibility when designing safety systems for different machine sizes, distances, and protection levels. Certifications such as c CSA US, c TÜV NRTL US, and TÜV Süd confirm compliance with stringent international safety standards. In addition, the device supports range reduction, allowing fine-tuning of detection distance when needed.
Applications
Ideal for access guarding, machine perimeter protection, and muting applications, this transmitter works seamlessly in conveyor systems, packaging lines, automated cells, and material-handling areas. The three-beam configuration provides balanced coverage for medium-height entry points.
Conclusion
The BEAM SAFETY DEVICE TRANSMITTER MULTIPLE LIGHT-MLD500-T3L offers durable construction, simple setup, and proven compatibility across the MLD500 series. Its combination of infrared precision, rugged design, and certified safety makes it a dependable choice for modern industrial safety requirements.
