Technical description
The secure reliable electromechanical connection achie-
ved with LEMO female cylindrical contacts is mainly due
to two important design features:
1. Prod proof entry on the mating side which ensures per-
2. The pressure spring , with good elasticity, maintains a
Contact material and treatment
LEMO female contacts are made of bronze beryllium (QQ-
C-530) or bronze (UNS C 54400). These materials are cho-
sen because of their high modulus of elasticity, their excel-
lent electrical conductivity and a high mechanical strength.
LEMO male print contacts are made of brass (UNS C
38500). Male crimp contacts are made of brass (UNS C
34500) or annealed brass (UNS C 38500) with optimum
hardness (HV) for crimping onto the wire.
