Sourcing components and techniques for hand-soldering Lemo connectors into custom cables
17 years old. Gear and prices may have changed since.
What the thread found
- Lemo connector parts and compatible cable can be sourced from general electronics distributors like Mouser and Digikey, or from specialized suppliers carrying branded options like Mogami cable.
- A soldering station rather than just an iron is preferable for consistent temperature control and quicker heat-up times.
- A heat sink tool should be used during soldering to prevent heat shrink tubing from prematurely shrinking onto the solder joint.
- Soldering small Lemo connectors is technically difficult and typically requires practice or prior experience to achieve reliable results.
- When ordering connectors in small quantities, having exact part numbers is necessary since vendors expect customers to specify precisely what they need.
- Lemo and Fischer manufacturers provide free catalogs and can direct buyers to authorized local distributors.
Depends on
- Discussion from 2009, so current availability and pricing may differ.
- No consensus on whether hand assembly is worthwhile compared to purchasing pre-made cables from professional fabricators.
- One participant specifically mentioned using Hakko 936 and Weller WD1000m soldering stations but individual tool recommendations are not universally applicable.
- No detailed guidance provided on connector specifications, pinout, or quality verification after assembly.
