Harwin M80-8532042
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.
Some connector styles are available manufactured and tested to BS9525 FO0O33. All other connectors in the range are designed to the same specification.

Jackscrew Usage Instructions
| Step | Instruction |
|---|---|
| 1 | For board mount jackscrews, fix to PCB with fixings tightened to 212cmN. Board mount fixings must be fitted before Wave soldering. Can be fitted before or after reflow soldering. Check tightness after soldering. Take care to avoid cross-threading. |
| 2 | On engaging, ensure correct polarity. Lightly push floating half until jackscrews touch. Turn floating jackscrews clockwise to engage with fixed screw. Repeat for the other screw. Screw in each jackscrew sequentially, applying max one turn each, until bottomed (evidenced by sudden increase in torque not exceeding 23cmN). Finger pressure may be required. Take care to avoid cross-threading. |
| 3 | On disengaging, turn floating jackscrews anti-clockwise sequentially, max one turn each, until disengaged. Connector can then be pulled apart. |
