The StandexMeder KSK1A522030 is a reed/magnetic switch that is used to indicate the position of a target in an industrial production setting. It is a single-pole, double-throw reed switch with two poles, each of which has one normally open (NO) and one normally closed (NC) contact. When the target is within the range of the switch, an electromagnet causes the contacts to change position, triggering an output on the switch. The KSK1A522030 is designed to operate in an operating temperature range of -5 to +65 degrees Celcius and a maximum voltage of 250 Volts AC. It is UL, cUL, and VDE approved.
