Electrical connectors for use in thermal couples circuits or DC circuits which is made of thermal compensation wires. Connectors consist of panel-side plugs (RRN25M, RRN25AM) and cable-side sockets (RRN25, RRN25A). Plugs are with no shell, straight or angular shell, sockets – with straight or angular shell. Plugs and sockets are secured with a screw joint. Сonnector is polarized with one key. Connectors are designed for internal mounting. Climate version – all-climate.
