This cable is a little over 100mm / 4" long and fitted with JST-PH 3-pin connectors on either end. 

We dig the solid and compact nature of these connectors and the latch that keeps the cable from coming apart easily. We're carrying these to match up with our STEMMA boards and sensors that have 3-pin connections - and the wires are even color coded! Red is power, ground is black and signal is white.

The 3 wires are 22AWG stranded, and the connectors have 2mm pitch.
