Standex-Meder Electronics: Miniature Reed Switch
The GR400 Series miniature reed switch can be used for a wide range of applications, including counting; end-limit detection; low power devices; movement or position detection; and presence, proximity, rotation, or speed sensing in industries including aerospace, automotive, HVAC, test and measurement, and security. The reed switch offers 0-10 W of rated power, a switching voltage of 0-180 V (vdc/vac), a maximum switching current of 0.5 A, and a maximum carry current of 0.8 A. It is available in an operating sensitivity of 7-30 Ampere-turns, and operating temperature range of -40° to 125°C. The breakdown voltage across the dynamically tested contacts is 230 vdc with a maximum contact resistance of 150 milliohms. According to the manufacturer, the series is tested to ensure a long life, capable of tens of millions of trouble-free switching cycles.
