Power Connector from Weidmüller
Push-In Connection System Replaces “Third Hand”
In power electronics the devices in a switch cabinet must be connected efficiently and cost-efficient. Weidmüller’s Omnimate Power BUF 10.16 is a PCB plug-in connector with the push-in connection system and wire-ready function. This may replace the “third hand” of the technician.
Power electronics devices have to combine high functionality with simple operation – this is particularly important for the wire connection. This needs to be performed safely and efficiently. Therefore Weidmüller offers its Omnimate Power BUF 10.16, a PCB plug-in connector with push-in connection system and wire-ready function. It is equipped with a settable operating lever (pusher) to create an open contact point, i.e. wire-ready. By that it may achieve a considerable time saving in wire connection.
The new female header in 10.16 mm pitch allows tool-free wiring for conductor cross-sections of 2.5 mm² (single wire) to 16 mm² with wire-end ferrule (AWG 12 …4) at a rated voltage of 1000 V (IEC), 600 V (UL) and a rated current of 76 A (IEC). The conductors for connection can be single- or stranded-wire versions, with or without wire-end ferrules.
The open wire-ready contact point is to simplify the connection of stranded wires without wire-end ferrules and wires with particularly rigid insulation which are often inflexible. The push-in contact is closed after plugging the wire into the contact point by releasing the locking clasp. When using cables without wire-end ferrules or with a small cross-section, the settable pusher is also advantageous. It keeps the contact point open after activation which enables the technician a quite convenient handling of conductors with short stripped off cable sheath or stiff insulation. The push-in function is retained with this contact system. In simple terms: The wire-ready connection is to replace the “third hand” or other tools in fiddly installation situations.
The female header Omnimate Power BUF 10.16 is equipped with a single-hand safety interlock, designed as a middle flange. The middle flange is snapped into place automatically without the need for operator intervention. Integration of the signal contacts independently of the installation width reduces the amount of space needed on the device and PCB. Intuitive plugging is possible in a single step – even without sight and under difficult installation conditions. Optionally, Weidmüller offers a variation with screw attachment, which the user can select according to the application.
Omnimate Power BUF 10.16 is available in various versions and numbers of poles: laterally closed; with flange; with screw/clip-on flange, these variations are all available in two to five-pole design. The laterally closed variations with middle flange or middle screw flange are available in two, three and four-pole versions.
