Up to now, Binder only had M8 receptacles for sensor-tube installation with LED hole in their range. Since many customers use only receptacles without LED holes, Binder is following this trend and is now offering these versions. The metal housing has a press-fit area with sealing beads. We recommend 5.77 + 0.03 mm for the press-fit hole. The diameter may vary depending on the material used, the walls and the thickness. The electronic connection is made using a dip-solder contact.
