Sensing Probe - Rockford Fosgate DETECT-A-FINGER RKC-502 Installation Manual

Sensing Probe

Two 18-inch pieces of
5
materials or custom made configurations may also be used. The only restriction is the total weight of the probe
assembly (including the clamp). The action-arm return spring is capable of returning 0.5 pounds maximum. The user
must determine and form the best shape to accommodate the particular part being run. This device must be designed,
constructed and arranged to create a protected area, and to prevent engagement of the machine. In pneumatic and
hydraulic-powered machines, this device must prevent energizing of the control valve when an operator's finger or other
part of the body is within the hazardous area.
The bottom of the drop rod, in its full down position, should barely clear the workpiece. This location allows for final
positioning. If special mounting brackets are fabricated, they must be able to support the sensing probe assembly and
withstand any shock and vibration that may be encountered during machine operation. Be sure to insulate any and all
special brackets from the electrodes.
