RIBBON – 102-A

Grein RIBBON Are made of a special PVC sheath within which is housed the sensor element which provides an electrical signal when any external crushing action is exerted on the board. A profile of aluminum plate complete the device for its attachment to the machine. These devices are designed to prevent injury to personnel against crushing by moving parts as sliding doors, gates, elevators plans etc. detecting an electrical contact via a control circuit. The system is guaranteed for a security level 1 or 3 “FAIL SAFE” in accordance with the use of control units and the number of conductors connected to the ribbon switches.

Dielectric strength 1000 V / DC Electrical resistance 0.3 ohm / Mt Temperature -15 +60 deg;C Degree of protection IP 67 Duration of operation 3 million operations PVC coating material Typical Weight 80 gr. / Mt ACCESSORIES Aluminum guide Grein Type 404 (for types 102-A e 102-F) Grein Type 406 (for type 202-L) in plastic too Type of terminals Terminals sealed welding for any sensor type LD or D for models 102-A and 102-F with wire 500 mm da 500 mm Terminals sealed with connectors type C only for model 202-L with wire 500 mm APPLICATIONS​ Grein EXAMPLES OF USE Are formed by two conductors in steel or phosphor bronze set at an insulator. The pressure exerted on the upper plate (along its entire length) causes the closure of the circuit by closing the switch end. SECTORS OF USE For industrial use: emergency switches on each type of machine commands along the conveyor belts sliding door guards, etc.. For civil use: reports of inputs for opening doors command disabled alarms for banks chronometers drive sports pools
