H-14HMitutoyo reserves the right to change any or all aspects of any product specication, including prices, designs and service content, without notice.An inspection certicate is supplied as standard. Refer to page U-11 for details.•Features a new coolant-proof design incorporating a high-performance rubber seal to provide higher reliability in the harsh factory environment. •The 0.4 mm air gap between the sensors is approximately four times wider than the conventional optical or magnetic sensors. Therefore, the chance of foreign objects lodging in this gap is lower. This air gap is the world's largest in this class of scale used on machine tools.•The de facto standard multi-point xing method for the frame is adopted, resulting in high vibration/shock-resistance. •Due to an improvement in the signal processing technique for the electromagnetic induction ABSOLUTE linear encoder, the repeatability is six times better than our conventional model. •Being compatible with the high-speed serial interface of each company listed in the table below, a direct connection to the NC controller is possible.
