Vehicle plug-in detector that will operate on any voltage from 10 to 30 volts AC or DC. This detector is virtually cross-talk free in most applications. It has been specifically designed to handle parking, drive-through and access control applications where solid-state outputs are required for both the detect and fail outputs. The sensitivity level may be changed, ranging from High to Very Low. The detector loop inductance should be between 20 and 2000 microhenries. Power- 12 to 30 volts DC.
