Electrical contact
Technical description
The secure reliable electromechanical connection achieved
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.

constant even force on the male contact when mated. The
leading edge of the pressure spring preserves the sur-
face treatment (gold-plated) and prevents undue wear.

LEMO male solder and 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.
Notes: the standard surface treatment are as follows:
– nickel: FS QQ-N-290A or MIL-C-26074C
– gold: ISO 4523.
