64-Position Style B Receptacle for Eurocard Backplanes
The TE Connectivity 1-1393641-4 is a 64-position, 2-row receptacle from the Eurocard DIN 41612 series, keyed as Style B. It accepts the matching Style B male header — the keying prevents a wrong-row insertion, which matters when the backplane has multiple slot types. Rated for -55°C ~ 125°C operation with a UL94 V-0 glass-filled PBT/polyester housing, it handles the thermal and fire-safety demands of industrial backplane environments.
Style B Keying and Mating Half
Style B defines the keying position and pin arrangement — this receptacle mates only with a Style B male header (e.g., TE 1393641-x or equivalent). The 2-row, 64-contact layout is fully loaded, so every position is wired.
Termination and Contact Plating
Through-hole solder termination — the pins go through the board and are wave-soldered.
