connectors can be positioned on the PCB using an automated pick-and-place procedure and then soldered on using the THR or SMT process (Figure 1). This allows electronics and device connection technology to be installed on the PCB in a single process step. It eliminates costs for additional PCB connection technology or manual installation processes. The device connectors also have uniform design-in types and can optionally be routed directly through a threaded hole in the housing or integrated into the device panel using a screw connection. Tolerance-Compensating Housing Screw Connection The Varioport housing screw connections compensate for production tolerances of up to 1mm between the PCB and housing feed-through (Figure 2). These deviations can lead to mechanical tension between the device port and PCB connection, putting strain on the solder joints. In the past, assembly jigs were used in the soldering process, or the front plates were produced using a precise, yet complex CNC process. This effort was intended to eliminate resulting malfunctions. The tolerance-compensating M12 screw connections offer an efficient and reliable alternative. The housing screw connections are easy to install, are self- adjusting, and lock reliably as soon as the cable connector is screwed onto the device port from the outside. The screw connection prevents water and dirt from getting into the device, even when it is not plugged in. The shock and vibration resistant screw connections are also shielded completely against electromagnetic influences, making them well-suited for use in harsh industrial conditions such as decentralized fieldbus distributors. Circular Connectors for all Situations The Phoenix Contact product range offers connection solutions for numerous application areas. For example, contact inserts with a complete shield connection to the PCB meet increased requirements for electromagnetic compatibility (EMC), in areas with welding robots. The shield spring integrated directly into the PCB connector makes additional measures such as soldering lugs unnecessary. The user benefits from low component costs and shorter installation processes. Straight or angled versions, signal connectors with up to 17 positions, and M12 compact hybrid connectors for transmitting signals and power complete the portfolio. For the first time, the entire infrastructure (from the control level to decentralized devices, sensors, and actuators) can be fully implemented using one standard. This does more than just reduce storage and maintenance costs. Thanks to the standardized interfaces, system planners and operators can also ensure easy integration of additional decentralized modules and that the existing infrastructure continues to operate without errors.
