Switch Box and Power Supply

The switch box is the interface between power supply and laser diode beam source. The integrated key switch and interlock mechanism ensure concordance with laser safety regulations. In addition, the inputs for analog and TTL modulation are made available via simple to use BNC connectors, the time-consuming wiring of a special adapter cable is avoided.

Schäfter+Kirchhoff laser diode beam sources are turned off when modulation inputs are open. This is implemented by internal pull-up resistors in the switch box, so that the beam source is immediately ready for use when closed.

The switch box can be grounded using either a clamping screw or a 4 mm phone jack. With a grounded switch box, the phone jack can also be used to connect an antistatic wristband or mat.

The shielded metal housing also isolates the contents from electro-magnetic irradiation. The operation of a laser source must conform to EN 60825.

Performance Features

  • Interlock chain for the remote deactivation of the laser
  • Laser power-up is only possible using the key switch
  • LED status indicator for “Laser ON”
  • Switch also provides output for external status indicator “Laser ON” (only with type SBP).
