* The model number of Heads without levers are same as those of Heads with levers without the numbers at the end.
    Example: WL-1H1100 becomes WL-1H without the lever.
    However, the WLH2 and WLH12 become WL-2H-1 and the WLGCA2 becomes WL-1H-1 for the Heads without levers.
    Other Heads are also available. Ask your OMRON representative.
