Light curtains for measurement, automation and control

3 models available in relations to the outputs.

The Metronconf Configuration software for PC, with graphic user interface, is supplied with each light curtain (models A and B only).

Beam spacing available: 5 … 75 mm.

Controlled height: 140 … 2525 mm.

Max. range:

  • 2 m – models with beams spacing 5 mm
  • 6 m – models with beams spacing 25, 50, 75 mm
  • 16 m – models with beams spacing 10, 30mm

Connections with M12 and M16 connectors. Up to 50 m of electrical connections with unshielded cables.

Possibility of connection of up to 8 Metron B light curtains as nodes of an RS-485 serial line for simultaneous detection of multiple dimensions and complex measurements.
