The ALNICO500 3X12MM is a 12 x 3mm Aluminium-Nickel-Cobalt Permanent Magnet is produced in a sintering casting procedure. This AlNiCo magnet features low temperature coefficient and adjustable magnetic moment. AlNiCo magnets have excellent temperature stability. Cylindrical AlNiCo magnets can be used with all Standex-Meder reed sensors/switches without any problems. AlNiCo bar magnets are suitable for the operation of most reed switches and should ideally be the moving part of the sensing application. Designed according to DIN 17410 standard.
