Additional probe card adapter safety interlock cable
The Model 174-7047-XX Safety Interlock Cable provides additional protection from electric shock at
the Keithley probe card adapter (PCA). The cable attaches to the prober top plate and the PCA so
that if you unlatch the top plate of the prober and lift it up to change a probe card or take off the PCA,
the interlock is tripped.

The Model 174-7037-XX cable can be used with customer-supplied PCA solutions.
Figure 8: Model 174-7037-XX interlock cable
The Model 174-7047-XX cable interfaces with your prober interlock through a relay contact. A
shorted prober contact engages the interlock circuit. An open contact interrupts the interlock, turning
off hazardous voltage.
