101-1-A-5/1D

101-1-A-5/1D is a 101 series general purpose CMOS drive SIL/SIP reed relay. It is a highest quality instrumentation grade reed switch. It is encapsulated in plastic package with internal mu-metal magnetic screen. This relay has very high coil resistances. A 5V dry versions may be driven directly from 74HC or 74HCT logic without the need for additional drivers. 74HC logic will drive up to 4mA at 5V, therefore a coil resistance of 1600 ohms is desirable to avoid running the IC at its maximum rating. Suitable applications are direct drive from CMOS, low thermal emf, thermocouple switching, very low signals.
