• Data interface: MarConnect (bidirectional), USB, Digimatic
• Energy supply: Battery life approx. 2 years
• IP protection category: IP 65
• Package contains: battery, instruction manual, setting standard (measuring range of 25–50 mm), case

Application:
• Avoiding workpiece damage: The non-rotating spindle has a touching contact, which prevents scratch marks on sensitive and finely machined surfaces
• Ideal for measuring thin metal foils without twisting and bending them
• Thread flank measurement by using thread wires: Both wire holders always remain in the engaged position with the non-rotating spindle
