If mounting on a non-magnetic surface, select DS-120-A with the thin screw bracket, but if mounting on steel or other magnetic materials then use 1/2” plastic spacers or select DS-120-B with integral spacers. Magnetic steel surfaces and ferrous magnetic parts should not be nearer than 1/2” from the sensor body. Care must be taken not locate other permanent magnets where they might affect the operation of the DS-120 sensor switch. Notes: 1) Do not use with relay coils without back emf protection. 2) Do not use to directly switch incandescent indicator lamps. (Consult factory) 3) Do not use to directly switch high inrush loads, capacitive or motor loads; nor, with wire runs longer than 100ft (Consult factory) Specifications are subject to change without notice.
