Y-coding has a hybrid mating face. It simultaneously supplies devices with both essential lifelines of power and data. The four data contacts enable transmission rates of up to 100 Mbit/s Fast Ethernet. The four power contacts transmit power of up to 300 W. Hybrid connections, such as Y-coding, can simultaneous supply multiple lifelines. This avoids using separate interfaces, saves resources and actively supports the miniaturisation of devices.

With THR (Through Hole Reflow) soldering technology, the connector is inserted into through-plated PCB holes. This can be done automatically with Pick&Place placement machines. These THR components are then soldered together with the components placed on the surface as part of a common reflow soldering process.

SMT (Surface Mounted Technology) connectors, in contrast to through-hole technology, do not have wire terminals, but are soldered directly to the solder pads on the PCB surface. This procedure is used for circuit board placement based on a uniform termination technique. It offers advantages as the use of SMT connectors eliminates the need for separate wave soldering.

Conventional soldering technology has been proven over decades; it ensures the highest level of mechanical stability and process safety. The soldering pins of the connectors are inserted into through-plated PCB holes. They can then be automatically and simultaneously wave soldered to other components.

A screw-on circular connector enjoys numerous benefits over non-round connectors: the connection is compact and, with sealing rings and the right torque, can ensure a high degree of protection. In addition, the handling is self-explanatory and simple, but time-consuming.

A contour is added to the device socket for the PushPull locking. The matching PushPull connector snaps into it. This enables a quick and tool-free mating of circular connectors, even in confined installation spaces. One click signals that a vibration- and shock-proof connection has been established. The PushPull locking mechanism is internationally standardised according to IEC 61076-2-010.
