ABSTRACT:
An application machine for staking contacts, e.g. circuit board pins, in a hole in a circuit board including an extendable staking anvil mounted on a toggle linkage. The staking anvil is provided with a bore and a fluidic sensor in communication with the bore to detect the presence of a clear circuit board hole for insertion of a contact in the hole. In the event no hole is present, or a contact has already been staked in the hole, a control system responsive to the fluidic sensor retracts the extendable anvil and prevents staking a terminal pin in the circuit board where no hole is present, or where a pin has already been staked in the hole.
