JANUS

Access control light curtains and grids with integrated Muting functions

JANUS:
A unique range covering all Muting applications

Safety light curtains with integrated Muting function.

The Janus series is the solution for the protection of a vast number of high-risk industrial applications, in particular those requiring a high level of integration of the Safety functions. For example, in the models with built-in Muting function, Janus guarantees the independence of the light grid from the control circuits of the system (often distant from the protected gate) and, where necessary, also the integration of the Muting sensors.

Settings of each function integrally performed via the main connector.

Muting integrated safety light curtains

Janus models with built-in Muting function guarantees the independence of the light curtain from the control circuits of the system and, where necessary, also the integration of the Muting sensors.The features of the Janus range include:

  • Settings of each function integrally performed via the main connector
  • Integration of the main safety functions, including self-testing of the solid state outputs, external device monitoring (EDM) and the Start/Restart interlock function
  • Integration of the Muting function for the MI models and of the Muting sensors for the ML and MT models
  • The utmost reliability in the field, thanks to the rugged construction and to the high level of immunity to external interference (optical, EMC, etc.)

Resolutions

The available resolutions cover every protection requirement:

  • 30 – 40 – hand protection
  • 90 mm – body protection
  • 2 – 3 – 4  beams – access control

With protected heights of up to 1,8 m
