S Series Circular Push-Pull Connectors

LEMO S Series Circular Push-Pull Connectors feature LEMO's chocolate bar shape in a redesigned outer shell, covering a different cable range than the existing S series. The IP50 and IP61 S series are offered as straight plugs or free sockets in 3-, 4-, and 8-contact varieties, including models with bend relief functionality. These self-latching Push-Pull connectors operate at -55°C minimum temperature while providing more than 40dB shielding at 1GHz (75dB at 10MHz). LEMO S series connectors use B series collets and are fully compatible with other S series sockets.
