Notes: 1N = 0.102 kg.
Notes: forces were measured on outer shells not fitted with contacts .
Mechanical endurance: 5000 cycles.
Mechanical endurance represents the number of cycles after which the latching system is still effective (1 cycle = 1 latching/unlatching at 300 cycles per
hour). The values were measured according to the standard IEC 60512-7 test 13a.
Electromagnetic compatibility (EMC)
and shielding efficiency
The electromagnetic compatibility of a device can only be
ensured by meeting a number of basic rules with the design
of the device and by carefully selecting components, cables
and connectors.
Electrical and electronic devices are to be designed to ensure
the following:
a) reduce the emission of generated electromagnetic
disturbance to a level where radios and telecommunication
and other devices can properly function;
b) electromagnetic immunity against electromagnetic
disturbance so that they can properly function.
When selecting a connector, screen or shielding efficiency
and low resistance to electric continuity between the cable
and the connector should be considered.
The design of LEMO connectors with metal shell and earth-
ing crown guarantee optimum shielding efficiency in all
applications where electromagnetic compatibility (EMC) is
critical.
The performance of a connector is measured through

shielding efficiency, a value that represents the ratio between
the electromagnetic field on the outside and the inside of the
shell. Our measurements are carried out according to the IEC
60169-1-3 standard.

The performance of S and B series connectors is compa-
rable to the results of measurements carried out on a pair
of FGG + PHG.1B connectors.
The performance of E and K series connectors is compa-
rable to the results of measurements carried out on a pair
of FGG + PHG.1K connectors.
