Sentinel Press Brake Guarding System

Sentinel is an advanced press brake guarding system designed for retrofit applications. Sentinel provides a high level of operator protection while maintaining machine productivity and performance.

Sentinel Optical Protection

The Sentinel laser transmitter and receiver are mounted to the upper beam of the press brake. A continuous block laser field protects the zone directly below the punch tip allowing the operator to hold the work piece as the tools close at high speed. If an obstruction is detected the machine is automatically stopped.

This close proximity protection allows the operator unrestricted access to the point of operation for increased productivity and unlike traditional light curtains, reduces fatigue by enabling the operator to remain standing in the same position.

Key Features

Sentinel Diagram


  • Mute point is easily set according to the material position and optically verified automatically on every cycle.
  • Multiple modes available to suit any shape and profile of work piece. At the press of a button simply select a mode that best suits each bend job to achieve the best level of productivity and performance.
  • Graphical user interface panel displays system and machine status in real time. Simple to follow instructions and messages make the system very easy to operate.
  • Integrated status LEDs for simpler and faster set-up and adjustment.
  • Automatic monitoring of speed and stopping performance.
  • Quick adjust brackets with tool lock to keep the transmitter and receiver clear during tool change.
  • Simple to set-up with adjustment after tool change taking only a matter of seconds.
  • Optional monitoring of additional machine safety elements including emergency stop buttons plus side and rear gate interlock switches with real time status displayed on the user interface panel.
  • Dual guarding option - install laser protection and a third party light curtain for even more flexibility. Simply select the protection that best suits the bend job.



RapidBend technology employs a patented progressive muting process that enables the press brake to close safely at high speed until the tool opening is only 6mm. This reduces the slow speed travel distance to enhance machine productivity. RapidBend is compatible with most synchronised CNC press brakes* and in comparison to other light or laser based systems, RapidBend can reduce machine cycle time by up to two seconds per cycle. This represents a significant saving in operating time and cost.

*For retrofit applications, RapidBend can reduce the minimum speed change point to 6mm, however results may vary depending on the press brake type and capabilities. Consult your Lazer Safe Retrofit Dealer for more information .


AutoSense is an automatic monitoring technology that tracks machine operation and performance in real time. AutoSense automatically monitors control commands, motion, direction, speed and stopping performance to maintain a high level of machine and operator protection. AutoSense also guarantees compliance with international safety standards that mandate automatic monitoring of machine overrun and safe speed.
