Electrical engineers designing next-generation devices face increasing pressure to deliver smaller footprints, higher signal integrity, and faster system integration cycles. Push-pull connectors provide a proven interconnect solution for these challenges—combining secure locking, fast mating, high-mating cycles, and hybrid signal / power capability in compact circular designs. These connectors are suitable for medical, military, industrial, and embedded systems industries.
Push-pull connectors are self-locking circular connectors that allow:
They are widely used in medical devices, industrial automation, test equipment, robotics, and defense electronics.
Push-pull locking systems have a highly user-friendly locking mechanism. When the connector is mated with the receptacle, the connector’s locking fingers (1) will lock into place in the receptacle and form a dependable connection between both parts. It cannot be separated by pulling on the connector’s cable (2). Instead, the connector can easily be separated from the receptacle by pulling on the outer housing (3).

LP locking (shoulder locking) connectors with machined keyed codes are available in ODU MINI-SNAP® Series L and ODU MINI-SNAP® Series K in 6 different standard sizes with diameters from 6.4 mm to 25 mm.
Connector shown in mated condition
Pulling on the cable or back nut will lock the “shoulders” firmly in place in the receptacle’s locking groove. This prevents the connector from being disconnected.
Pulling on the outer housing will cause the shoulders to emerge from the locking groove, making it easy to disconnect the connector.
FP locking (finger locking) connectors from ODU with half shell coding (ODU MINI-SNAP® Series F), and with machined key codes (ODU MINI-SNAP® Series B and ODU AMC®) are available in 5 different standard sizes with diameters from 9.4 mm to 18 mm.
Connector shown in unmated condition
Pulling on the cable or back nut causes the locking fingers to grip harder into the locking groove in the receptacle. This prevents the connector from being disconnected.
Pulling on the outer housing will cause the fingers to emerge from the locking groove, making it easy to disconnect the connector.
A push-pull connector is a self-locking circular connector system that allows fast mating and secure retention without threading. Electrical engineers use push-pull connectors to ensure reliable signal integrity, vibration resistance, and quick disconnect in compact electronic systems.
Push-pull connectors are preferred because they provide:
They are widely used in medical devices, endoscopy systems, and industrial automation electronics.
