LEMO E-Series Connector

LEMO E-Series Connector

INDUSTRIAL WATERPROOF PUSH-PULL CONNECTORS

LEMO E-Series connectors are used in military applications, medical devices, oil and gas applications, public sector, industrial control and test & measurement environments. All models of this Series are waterproof and watertight when mated and correctly assembled to an appropriate cable to give a protection index of IP68 as per IEC 60529 standard (IP66 in unmated condition). Self-latching connectors with stepped inserts for alignment (of multipole version) and rugged housing for extreme working conditions.

Note: the various tests have been carried out with FFA and ERA connector pairs, with chrome-plated brass shell, PEEK insulator and silicone O-ring.

1) minimum operating temperature is -20°C for sockets fitted with an FPM (Viton®) O-ring.
2) IP68 achieved providing that the cable is perfectly circular and that assembly process ensures a high integrity seal.
