The LMK-115X/11X/13X and LMKF-115X/11X/13X scanning head with integrated electronics includes all of the necessary signal conditioning to deliver the final output signal. They can be combined with measuring scale type LMB series. (see catalog). The grating pitch must be the same for the scanning head and the grating scale. As an option, an integrated limit switch function can be realized. These read heads are IP-67 rated and are insensitive to environmental pollution like grease, oil, coolant, dust and dirt.
