Machine safety and press brake guarding.
Safety light curtains, press brake guarding, press controls, safety valves, palm buttons, safety mats and die blocks, made in Canada and supplied to plants across the country.
Safety light curtains
ISB MX Type 4 safety light curtains, made in Montreal, for press brakes, power presses, robot cells and machine openings. Choose the detection capability for what you need to protect, then the protective field height that covers the opening.




| Detection capability | Typically protects | Protective field heights |
|---|---|---|
| 14 mm | Fingers, close to the hazard | 300 to 1200 mm in 150 mm steps |
| 22 mm | Hands | 300 to 1800 mm in 150 mm steps |
| 30 mm | Hands | 300 to 1800 mm in 150 mm steps |
| 38 mm | Hands at a greater safety distance | 300 to 1800 mm in 150 mm steps |
| 82 mm | Body and access openings | 300 to 1800 mm in 150 mm steps |
For large openings, robot cells and CNC tables, the SLS-400 area scanner sets up programmable warning and stop zones. Each light curtain set is an emitter and a detector. Two detector versions are available: a standalone version for general machine guarding, and a version that works with the press brake guarding system below. The right resolution and mounting distance depend on the machine's stopping time, so we confirm it with you before you order.
