E Connectors

LEMO E Connectors are watertight self-latching connectors with stepped inserts for alignment and rugged housing for extreme working conditions. These E connectors feature unipole, multipole 2 to 106 contacts, high voltage, and push-pull self-latching. The E connectors include solder or print contacts, over 22 shell styles, and 7 sizes. These E connectors operate at -55°C to 200°C temperature range. The E connectors offer watertight connection (IP 68/IP 66), polarization by stepped insert (half-moon), and 360° screening for full EMC shielding.
