This Eddy trough proximity board for Twilight Zone features newly redesigned eddy circuitry & offers improved sensitivity & reliability over the original #A-16534 board.
Features Include:
New sensor coil
New sensor metal bracket
Multi-turn adjustment - allows precise and reliable calibration
Better detection distance
Revised & improved electronic circuit design
Highest quality parts & manufacturing processes.
This product comes complete with a sensor board & it's metal mounting bracket. This board is plug-n-play compatible with the original board & comes with 4 new nylon mounting posts.
The improved sensitivity of this board allows the sensor coil to be mounted further from the balls in the trough. This reduces the incidence of smashed sensors (the biggest problem on the original board). The detection sensor provided here has soldered wires to alleviate the problems found with the original board's Molex connectors.
Bally reference #A-16534 & A-16528.
