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.
Connector annotation structure:
| SHR | 20 | P | 3 | E | G | 7 |
| Connector diameter | Design: Unit-side connector: P – without shell PK – straight shell SK – angular shell Cable-side connector: P – straight shell U – angular shell | Number of contacts | Type of shell end nut (1): E – for shielded cables N – for unshielded cables | Contacts type (2): Panel-side connector: SH – plug G – socket Cable-side connector: SH – socket G – plug | 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
Examples:
Unit- side plug SHR28P4ESH5-K
Cable-side socket SHR20P4ESH8-K
