Dimension diagram Dimensions in mm Mounting and connector kits are not included in delivery, but are available as accessories. The maximum diameter of the mounting points is 10 mm. Before mounting the device, ensure sufficient insulation between the device and the vehicle or the mounting points (min. 11.4 mm to other parts). If the device is mounted on a metal or conductive subsurface, this subsurface has to be at earth potential (Kl.31; vehicle mass). Deflection max. 1 % of the length or width of the PCB Coating thick-film lacquer Weight 52 g ±2 g 5 0 The connector XK1A is 1mm longer than...
