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 (UNS C
54400). This material is chosen because of its high
modulus of elasticity, its excellent electrical conductivity
and a high mechanical strength.

The leading edge of the pressure spring preserves the
surface treatment (gold-plated) and prevents undue wear.

LEMO male solder 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; and Gold: ISO 4523.
