254 DF / HE901

The 254 series is a double sided, 2,54 [.100] pitch, range of connectors for printed circuit boards. Both direct or indirect connections could be made: - For direct connection, the female receptacle mates with a 1,6 ± 0,2 [.063 ± .008] printed circuit board - For indirect connection, the female receptacle mates with the male plugs

A well-proven technology The 254 series uses a 2,54[.100] pitch, double sided. The arrangements available are from 2x13 contacts to 2 x 55 contacts. The contact technology is based on a turning fork concept.

A simple choice of solutions, adaptable to all type of configurations For motherboard: female receptacles with straight PC tails (Y). For extender boards: female extender with right angle PC tails (YC). For mounting on cables: female receptacle with solder cup contacts (Z).

In case of direct connection: the female receptacle mates directly with a 1,6 [.063] printed circuit board. In case of indirect connection, the male plug with SMT contacts (U) is used.

Various polarization system are available (for both direct or indirect connection).

The 254 series complies with here below standards:

The 254 series is a single sided, 2,54 [.100] pitch, range of connectors for printed circuit boards. Both direct or indirect connections could be made: - For direct connection, the female receptacle mates with a 1,6 ± 0,2 [.063 ± .008] printed circuit board - For indirect connection, the female receptacle mates with the male plugs

A well-proven technology The 254 series uses a 2,54[.100] pitch, single sided The arrangements available are from 11 contacts to 47 contacts for 254 series and 6 contacts to 24 contacts for 508 series

A simple choice of solutions, adaptable to all type of configurations 2 receptacle versions are available: Type A: Type B: - Floating contacts

- Removable contacts

- Terminations in two rows, 2,54[.100] pitch

- Terminations in two rows, 5,08[.200] pitch

For motherboard: female receptacle with straight PC tails (Y) For mounting on cables: female receptacle with solder cup contacts (Z)

For extender boards

Female extender with right angle PC tails (YC) Type B only Removable contacts

Terminations in two rows, 5,08[.200] pitch

In case of direct connection: the female receptacle mates directly with a 1,6 ± 0,2 [.063 ± .008] printed circuit board

In case of indirect connection, the male plug with right angle PC tails is used. 3 versions are available A: standard types as per norm B: open ended mounting ears

C: without mounting ears

Various polarization system are available (for both direct or indirect connection) The 508 series is a derivate version of the standardized range, with only odd-numbered contacts mounted The 254 series complies with here below standards:
