Plug-in connection T SCHAERER Spare Parts 3370072729

A plug-in connection creates a secure, quick-release electrical link between a coffee machine and its internal components or external modules. Instead of fixed wiring, the connection uses mating plugs that lock together, allowing the operator to disconnect and reconnect circuits without tools or exposed terminals. This method speeds up servicing, module swaps and safety isolation in professional coffee equipment.

The T 4-4-4 configuration indicates three separate four-pin plugs housed in a single unit. Each plug carries power, control signals or sensor data, keeping the circuits organised and standardised. The operator aligns the plugs, presses them together until they click, and confirms the connection is locked before powering the machine on. To disconnect, the release tabs are pressed and the plugs pulled apart.

Construction is moulded plastic housings with metal contact pins. The design prevents incorrect insertion by shaping the plugs so they only fit one way. Cleaning is limited to wiping the exterior with a dry cloth to remove dust; no solvents or moisture should reach the contacts.

This spare part fits SCHAERER coffee machines that use the T 4-4-4 plug-in system. It appears in the catalogue under Coffee Equipment Spares, Electrical Connections.
