Multiple light beam safety devices
M4000 Standard A/P

Intelligent wiring and maximum availability

Your Benefits

  • Economical active/passive variants minimize the wiring and installation workload.
  • Resilient and rugged design for high system throughput, even under special ambient conditions
  • Mounting grooves on three housing sides ensure greater mounting flexibility and facilitate integration with the machine
  • User-friendly interfaces and status indicators simplify commissioning and maintenance
  • Fast startup times due to configuration directly on the device, without the need for a PC
  • Reduced downtimes thanks to all-around-visible LEDs and diagnostics displays


Intelligent wiring and maximum availability

The M4000 Standard A/P multiple light beam safety device is the economical solution for access protection. It is particularly economical since only the active side must be wired, which reduces the installation time. The M4000’s large scanning range and extensive functions provide efficient access protection and maximum reliability. The functions are easy to understand and are set via the configuration keys located directly on the device. Integrated functions and status information enable quick commissioning and minimize machine downtime. The modular concept enables a high level of machine safety since device properties can be adapted to meet specific application requirements. In addition, sens:Control devices, accessories, and services complete the product offering and form packaged solutions designed specifically for industrial environments.
