Dimming Connector (J2)

A dimming voltage or potentiometer, plus optional backlight mode and disable logic inputs are applied via J2, which is a polarized 5-pin inline, 2.5 mm pitch header, tin plated with a friction lock. The connector is equivalent to the Molex 5268-NA ‘SPOX’ series, part number 22-05-7055. The recommended mating connector is a Molex 5264-N series housing, part number 50-37-5053 and Molex 5263 series crimp pin, part number 08-70-1040. The recommended wire size is 22-28 AWG stranded. Refer to on page 19 for more information.

Backlight Power Connector (J1)

Backlight power (VH) is applied via J1, which is a polarized 3 pin, 3mm pitch header with gold plated (15μ") contact surfaces and a release latch. J1 is equivalent to a Molex 43650-0301 (“Micro-Fit 3.0” series). The recommended mating connector is a Molex part number 43645-0300 (housing) and Molex part number 43030-0008 (crimp pin). The recommended wire size is 20 AWG stranded.
