The Sentinel Plus guarding system features a laser transmitter and receiver that are mounted to the upper beam of the press brake. A continuous block laser field protects the zone around the punch tip allowing the operator to safely hold the work piece as the tools close at high-speed. If an obstruction is detected the machine is automatically stopped.
Sentinel Plus can be retrofitted to most existing press brake models and provides a complete safety solution that includes advanced optical protection, monitoring of the press brake control commands and actions, control and monitoring machine safety elements and more.
Complete optical protection
The laser field is processed by the receiver and divided into three continuous zones to detect obstructions entering from the front, sides and rear of the tool area. The front zone provides protection forward of the tool while the middle zone protects the area just behind the tip of the punch. The rear zone provides additional protection for the open gaps created when segmented tooling is used. The protective zones are independently and automatically muted to suit different shape work pieces allowing parts to be formed safely at high speed to achieve maximum productivity.
RapidBend Plus performance technology enables your machine to operate faster and with less restrictions. RapidBend Plus works with flat sheets and box profile parts so the machine can close at high speed right down to 2mm above the material to significantly boost your productivity.
Advanced machine monitoring
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.
External Device Monitor (EDM)
Sentinel Plus provides the option to connect and monitor up to four external devices such as valve sensors or relays. The EDM response time is configurable and the status of each external device is displayed on the user interface panel in the event of a device failure.
Sentinel Plus systems are supplied as standard with a free-sliding linear mounting bracket system that attaches the transmitter and receiver to the upper beam of the press brake.
Dual guarding support
- the best of both worlds
Sentinel Plus Automatic
Automatic motorised adjustment
Available as an optional upgrade, the Automatic Brackets automate the process of adjusting and positioning the transmitter and receiver during tool change. The Automatic Brackets incorporate a compact motorised drive system that is controlled via the Sentinel Plus user interface panel with simple one touch operation.
Sentinel Plus XL
The robust guarding solution for long press brakes.
Sentinel Plus XL provides wider optical coverage and protection for a range of tools that are typically used on long press brakes and the system ensures stable operation even under extreme operating conditions.
*When the Sentinel Plus XL option is installed, there are some performance and functional differences compared with the standard Sentinel Plus configuration. Consult your Lazer Safe Retrofit Dealer for more information.
