Interlock wiring
The DB9 connector is used to connect the sensor’s interlock circuitry to the RF
Source. The internal interlock switch is connected to
Pin 1
and
Pin 6
of the DB9
connector. The interlock is normally open, attaching an interlock bracket to the
sensor will close the interlock circuit.
