Top laser safety with the KUKA LaserSpy 4.0

Perfect protection against laser beams: the KUKA LaserSpy is a TÜV-tested laser safety sensor which monitors the laser protection wall electronically and actively. Escaping beams are stopped before they can do any harm – ensuring optimum laser safety for your system and personnel.

Sensor for active laser protection screens

A decisive factor for the laser safety of systems in the event of a malfunction is the duration of exposure. One way to economically meet the necessary safety standards is to use an electronic, actively monitored protection wall. This is why KUKA has developed the KUKA LaserSpy safety sensor. It is quick to install and easy to use. Get your systems ready for more laser performance.

How the KUKA LaserSpy works

The KUKA LaserSpy is an optical sensor which monitors the light-proof space inside a protective double-panel wall. This is where it detects continuous or pulsed laser radiation in the near-infrared (NIR) wavelength range (820 to 1,100 nanometers) and reacts accordingly.

Each sensor consists of multiple detectors in a circular arrangement around a kernel. The KUKA LaserSpy is able to monitor a range of 3.5 meters in every direction. This means that only one sensor is needed, even for large-area elements.

How does the KUKA LaserSpy provide protection when it matters?

  • A laser beam penetrates the first wall. The highly sensitive KUKA LaserSpy measures the incoming radiation.
  • Before the laser beam is able to penetrate the outer protective wall, the  KUKA LaserSpy opens the safety circuit.
  • The KUKA LaserSpy then switches off the Emergency Off circuit via the beam source.
  • The response time of the KUKA LaserSpy is so quick that thin double walls with a gap of around 35 millimeters suffice even for high laser power.

The KUKA LaserSpy 4.0 meets the most stringent safety standards

The KUKA LaserSpy provides more laser safety in welding cells.

Benefit from the following advantages:

  • Emergency Off function through active intervention in the safety circuit of the laser source
  • Suitable for all lasers with highest radiation in near-infrared range of wavelenghts (820 to 1,100 nanometers), irrespective of the installed laser power
  • Simple installation: Preparation using a drilling template; fastening by means of self-tapping screws without having to open the electronics housing
  • Self-monitoring sensor which tests itself for malfunctions

Retrofit in existing systems

We can retrofit your system quickly and easily with the KUKA LaserSpy. The only requirements are: the booth of your system has a double-panel wall, the distance between the two outer panels of the double wall is at least 35 mm, and the wall elements are of light-proof design.
