In this total length the casing is 7,5 mm long. On this casing is the thread with 5 mm length connected and out of the thread the axis rises with 12,5 mm length. The axis has a diameter of 6 mm and is flattened on a length of 12 mm. It is made of black plastic. Its head has a slot and ends in corner radius. The thread, which surrounds the axis, has the screw measure M9 x 0,75 mm.The four solder contact pins are 0,8 mm wide (one of them) and they are arranged in a raster in a distance of 2,5 mm. The bented pins, which are sticking out to the front, are necessary for the electrical function, in which the fourth pin has no electrical function.In the back range of the casing the metallic edge-socket connector is mounted. The connector will be fixed at the printed circuit board by pressing in the snap in pin. Between the two snap in holdings the distance is 13 mm. The holders latch in the board and fix the potentiometer mechanically.Useful hint:The potentiometer is soldered on the circuit board. You should have mechanical skills and experience in soldering to replace it. Â
