Round Male 4 pin 17mm Threaded Spindle Connector

This is a 4 pin replacement connector that is found on the back of typical spindles. The dimensions of this male 4 pin spindle connector is: Pin spacing (pitch): 0.2" (5.08mm) Mounting hold spacing is 0.7" (18mm) Thread for mating connector is 17mm This connector is mounted on the back of a typical spindle that has mounting dimensions of 18mm or 0.7 inches. There are four connections, three of which are used for the three coil windings for spindles. The fourth connector can be used for protective earth ground. If there is no way to connect the fourth pin, we typically use one of the screws of the flange to connect the protective earth. This position has continuity with the complete spindle housing. The mating connector is this 17mm male spindle connector. To establish a soldered connection between the cable and connector pins, follow these steps: Each pin features a cup-shaped lead on its rear end, designed to hold a pool of solder. Start by applying rosin core solder inside this cup. Also, tin the end of the wire that you'll insert into the cup by applying rosin core solder to it. Heat the cup already containing some solder, and while it's melted, insert the tinned wire into it. The use of rosin core solder on both the cup and wire end ensures that the flux aids in forming a strong solder bond between the two components.
