DIN 41612 Type B Backplane Receptacle — 64 Positions, 0.100" Pitch
The TE Connectivity 650860-5 is a 64-position DIN 41612 Type B receptacle from the Eurocard series, designed for backplane and card-edge interconnect in industrial and telecom equipment.
Style B vs Type C — What the Keying Means for Your Backplane
The Style B designation (DIN 41612 Type B) means this receptacle mates with a male header that has a specific keying and contact arrangement — 64 positions in two rows.
The gold contact finish on the 650860-5 is standard for DIN 41612 connectors that see repeated mating cycles in backplane applications — think card swaps in a telecom chassis or industrial controller. Gold resists oxidation and fretting corrosion better than tin, so the contact resistance stays stable over hundreds of insertions.
