描述：Microbus with earth plane This Microbus is designed for use with DIN 41612 64 // 96 or 96 // 96 connectors. Pins 1 and 32 on rows a and l are for 0 V with full 0 V display panel on one side of the plate. Pins 2 and 31 on rows a and c are for Vdc, which therefore clears 56 separate signalling lines. The width of the plate is from 42 → 84 E. The female 64 // 96 and 96 // 96 solder or wrap connectors are ordered separately. High reliability thanks to the metal holes. Minimum crosstalk. DIN 41494 (KM6-II) compatible. Protective lacquer to prevent solder bridges.
