Professional-grade miniature magnetic reed switch - • GR560: The core product series representing a miniature, general-purpose glass-body reed switch featuring high-reliability rhodium contacts. It uses a single-pole single-throw, normally open (SPST-NO / Form A) contact arrangement. • 35/40: The Ampere-Turns (AT) sensitivity range. This indicates that the switch requires a magnetic field strength between 35 AT and 40 AT to actuate (close) its contacts. • AT: Stands for Ampere-Turns, which is the standard unit used to measure the magnetic sensitivity of reed switches - Parameter Standard Value Circuit Configuration SPST-NO (Form A, Center Gap) Max Switching Current 1.0 A (AC/DC) Max Carry Current 1.5 A (AC/DC) Max Switching Voltage 125 VAC / 100 VDC Power Rating 10 VA / 10 W Glass Body Dimensions 2.3mm Diameter × 14.2mm Length (Max) Overall Length 54.0 mm Operating Temperature -40°C to 125°C
