The Black & Webster Protectoswitch is an ideal way to protect your operators from pinch point accidents.
The SAF-6N Protectoswitch is an electro-pneumatic version and can be installed on our Black & Webster Electropunches or on a variety of equipment such as riveters, punches, spot welders, and staking machines. Its simplicity of design is the key to providing years of maintenance-free operation.
How it works? When the operator initiates a foot switch to activate the machine, the Protectoswitch intercepts the start signal and automatically drops a probe around the work area. If an obstruction is sensed the machine will not fire until the obstruction is removed. If the work area is free of obstructions, the probe falls to its full stroke, which closes an actuating switch to fire the machine.
The Protectoswitch is supplied with a straight 24" long aluminum probe that must be shaped to the configuration of both the lower and upper tooling. Plastic sleeves are available in 1 1/2" and 2 1/4" and 3" diameters for adapting to the end of the probe.
