Standex-Meder Electronics has announced the GR400 series miniature reed switch. This 10 mm reed switch, created with a patented, highly automated production process, provides a low-cost solution 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. These applications span many industries: aerospace, automotive, HVAC, test and measurement, security and more.
The GR400 offers improved electrical characteristics, with zero to 10 W of rated power, a switching voltage of zero to 180 volts (VDC/VAC), a maximum switching current of 0.5 amps, and a maximum carry current of 0.8 amps. It is available in an operating sensitivity of 7 to 30 Ampere-turns, and operating temperature range of -40°C to 125°C. The breakdown voltage across the dynamically tested contacts is 230 VDC with a maximum contact resistance of 150 milliohms.
The GR400 series is also RoHS compliant, UL recognized and REACH compliant. The GR400 is available in a contact form 1 A (SPST) (normally open contact), center gap.
