* Pictures are placed for illustration purpose only. Appearance of real component may differ.
Dust- and splash-proof connectors for DC and AC (up to 3 MHz) circuits with voltages up to 850 V. Connectors consist of a plug and a socket, which can be either panel-side or cable-side. Panel-side of the connector can be without shell, with straight or angular shell. Cable-side – with straight or angular shell. Connectors are suitable for shielded or unshielded cables. Plugs and sockets are secured with a screw joint, connector is polarized with one key.
