Product Overview

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 through-board, and surface mount termination. Male connectors are available for crimp, vertical or horizontal (90) through-board, 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 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 FO0O33. All other connectors in the range are designed to the same specification. For cable assembly specifications see Component Specification CO49XX.

Instructions for Use - Connectors with Jackscrews

Connectors are fitted with jackscrews to provide mechanical assistance for satisfactory engagement and separation, especially where forces are high or access is restricted. Jackscrews also offer a locking feature against disengagement under adverse conditions.

1. Board Mount Fixings: For connectors with board mount jackscrews, fix to the PCB with fixings tightened to a torque of 212cmN. Board mount fixings must be fitted before Wave soldering. They can be fitted before or after reflow soldering; check tightness after soldering if fitted before. Note: Align male and female threads carefully to avoid cross-threading.
2. Engagement: After ensuring correct polarity, lightly push the floating half until jackscrews touch. Maintain pressure and turn one floating jackscrew clockwise until it engages the fixed screw. Repeat with the other screw. Screw in each jackscrew sequentially, applying a maximum of one turn per screw, until the connector is bottomed (indicated by a sudden increase in torque, not exceeding 23cmN). Finger pressure at the connector center may be needed for full engagement. Note: Align male and female threads carefully to avoid cross-threading.
3. Disengagement: Turn each floating jackscrew anti-clockwise, ensuring even loading by turning each screw sequentially for a maximum of one turn until disengaged. The connector can then be pulled apart.
