摘要: A magnetic target is provided for use with a proximity switch. The includes cylindrical body tube having an open end that partially defines bore. stationary magnet located within the bore opposite end, and movable disposed between end. An adjusting member received into bore, contact surface of engages magnet. When axially displaced, causes corresponding displacement relative to magnet, eventually causing flux field each expand in radial direction away from longitudinal axis may be either axially-magnetized samarium-cobalt magnets or neodymium magnets.
