DESCRIPTION OF CONNECTOR AND INTENDED APPLICATION

A range of 2mm pitch male and female rectangular, fully shrouded unsealed connectors with replaceable

contacts for interconnecting board to board, cable to board and cable to cable. The range covers 2 to 96

ways, in various application methods. Female connectors are available for crimp, vertical throughboard and

surface mount termination. Male connectors are available for crimp, vertical or horizontal (90°) throughboard

and surface-mount termination. Pre-cabled contacts and cable assemblies are also available in various

options.

The connectors are provided with a range of contact terminations (as shown in Appendix 1) that are gold or

tin plated. The contact zone of a gold plated contact is hard acid gold of 98% purity.

The connector is intended for use as a low voltage connector in high packing density electronic equipment.

The connector is polarised to prevent mis-matching and can be produced with a latching feature (L-Tek) or in

a jackscrew (J-Tek) format, with or without board mounting.

L-Tek and J-Tek connectors are available with low-frequency (LF) contacts, while mixed technology (Mix-

Tek) connectors are also available with jackscrews, with a choice of power or coax contacts.

NOTE: Some connector styles are available manufactured and tested to BS9525 F0033. All other connectors

in the range are designed to the same specification. For cable assembly specifications see Component

Specification C049XX (where XX is latest issue).
