SIGUARD Switch Strips

The SIGUARD Switch Strips protect against pinching or crushing on dangerous edges.  If the switch strip is actuated or if a fault occurs in the switch strip or connecting cables, the output circuit trips and the drive mechanism is halted. Even the slightest actuation changes the IR signal in the rubber profile and trigger the STOP signal.

The complete monitoring system is comprised of 3RG7855 Switch Strip and a 3RG7857 evaluation unit for a Category 4 approval according to EN954-1.

• Transmitter/Receiver Sensor Range is 0.5 - 10m
• Rubber Profile available in 1, 2.5, 5 and 10 m lengths
• Aluminum Mounting Channel is available in 1 and 2.5 m lengths

SAFETY MATS

Safety Mats are used for intrusion detection into hazardous areas around power presses, machinery and robots. Detection results in a stop command being sent to machinery or robot controls. The presence of operators in hazardous areas not visible from the equipment controls location is also detected, in this case pressure sensitive safety mats prevent restart of the equipment. Safety mat systems consist of the mat itself and a mat controller to interface with the machine controls

Bircher SafeTec safety mats are a pressure sensitive design. Copper clad epoxy plates are encapsulated in a black polyurethane compound. Copper, the selected contact material, offers superior corrosion resistance compared to commonly used safety mat contact plates.

• 2 wire & 4 wire failsafe wiring options
• Custom sizes and shapes available
• Multiple zone mats
• Safety Category 3 systems available, on request with BG certificate, third party approved BIA.

SAFETY EDGES

Pressure sensitive sensing edges or edge sensors are used as signalling and initiating devices on machinery or as safety devices where pinch points exist on automatic machinery doors. Edge sensors for signalling or initiating applications are typically actuated by an operator's deliberate hand or foot motion. Edge sensors in safety applications stop or reverse automatic doors or moving machinery. These sensing edges offer cushioning to absorb door or moving machinery over travel that occurs between the stop command and the actual stand still of the motion. Sensing edge systems consist of the edge itself and an edge controller to interface with the equipment controls
