Dimensions and Installation Parameter Details Plate overall length 76 mm Plate depth 51 mm Inner plate depth 40 mm Mounting pitch 30 mm Thickness/height shown 20 mm Dimensions are in millimetres unless a different unit is shown. Lettered dimensions refer to the matching drawing in the catalog; check that drawing before machining or installing the product. NAMUR describes the actuator interface, not a guarantee for every actuator. Check the mounting pitch, shaft engagement, enclosure clearance and switch signal against the mating actuator. Mechanical switches are intended for ordinary service; any intrinsically safe proximity-switch application requires the correct complete circuit and marked device rating. For detailed product dimensions and mounting drawings, please download and refer to the PDF catalog. Estimated Weight 16 g. This is a calculated reference estimate for this product, not a manufacturer-published or measured product weight. Packaging is excluded. Assumed 76 × 51 × 20 mm enclosure reference envelope × material density 1.05 g/cm³ × 20% equivalent solid fill. The fill factor is an estimation assumption; actual switch and mounting hardware weights vary.
