Coto 3502 Series

The 3502 surface-mount low thermal EMF reed relay series from Coto features available coil voltage options of 5V_DC and 12V_DC with a switching voltage of 200V and switching current of 0.5A. The 3502 is designed to offer a low thermal EMF range from <0.5µV to <5µV. An epoxy coated steel shell provides magnetic shielding, with hermetically sealed contacts for long life and high reliability. The 3502 series is ideally suited to the needs of instrumentation, data acquisition and process control.
