Further, in case of ES and ES, the areas can also be selected with external signals. Conforming to EMC Directive Compact size for space-saving Its size is half of a conventional model, and the attached cable orientation is freely adjustable. ence, it can also fit in a small GV. Moreover, sensitivity adjustment can be done on the front face..9 in mm. in Sensitivity adjuster 8 mm.8 in ong range m. ft type has a long range of m. ft. Even on a high-speed GV, it can detect an object quite early so that slowing down and stopping are smooth.
