Wires, connectors SSHR28U4ESH8 socket

Connectors are suitable for use in DC and AC (with frequencies up to 2 MHz) electrical circuits at voltages up to 850 V. Connector consists of two units: a plug and a socket. SHR plugs and sockets are designed for installation either on equipment cases or on cables.

Panel-side of connector has either no outer shell, straight or angular shell. Cable-side connector has either a straight or angle shell.

Connectors are suitable for shielded or unshielded cables, suitability depends on the shell end nut construction. Contact diameters: 1.5 mm, 2.5 mm, 3.5 mm, 5.5 mm, 9.0 mm (contacts with 5.5 mm and 9.0 mm are extractable). Contacts are silver- or nickel-plated.

Connectors are built for indoor and outdoor installation (considering enclosure protection is provided) in boreal-climate design.

Contacts layout symbolic notation

Notes:

• Unit-side connector without shell has no end nut. “E” is a dummy symbol in this case.

• Cable-side connector contact type is notated in accordance with a panel-side connector it suits.

• Left-banded cable-side plugs have an additional “L” symbol in annotation
