| Mercury wetted reed relays |
|
|
| These relays feature bounce-free operation, which makes debouncing circuitry unnecessary. The contact resistance is low and stable, thus assuring long operational life. These relays, however, must be mounted within ±30 degrees from vertical ("UP" arrow on the body pointing upward) for proper operation. |
|
| High voltage reed relays |
|
|
| In addition to general purpose reed relays with the typical open contact breakdown voltage of 300 VDC, our product line includes high voltage relays with breakdown voltages (open contacts) from 1,000 to 15,000 VDC. These relays are typically used in communication devices, test equipment and high voltage signal transmission circuits. |
|
| Low thermal EMF reed relays |
|
|
| Heat generated by the energized coil of a reed relay can create thermal EMF voltages between the contacts and external terminals. This thermal EMF voltage may cause erroneous measurements, especially in high precision (accuracy) instruments, where voltages that are being measured are often in the millivolt or microvolt region. Our low thermal EMF relays, by employing special bobbin construction and reed switch assembly techniques, have a greatly reduced thermal EMF reading of 1 to 3 µV/°C. As a comparison, general purpose reed relays have typical thermal EMF readings of 30 to 50 µV/°C. |
|
| High frequency (RF) reed relays |
|
|
| To eliminate the effect of reflected waves in switching of RF transmission lines (circuits), the matching of circuit impedances is necessary. Our reed relays with coaxial geometry of electrostatic shields are best suited for switching RF transmission lines. Our product line features 50 Ohm characteristic impedance, high circuit isolation and low insertion loss. |
|
| High insulation resistance reed relays |
|
|
|
When switching extremely low currents and scanning many inputs using two or more relays, the leakage current of the reed relays must be as small as possible. For such applications we have relays built with high insulation resistance reed switches. Also the internal construction of the relay, including complete epoxy encapsulation, results in reed relays with insulation resistances of 1x10E+12 Ohm or greater, between mutually isolated terminals. For switching currents lower than 10µA, we recommend using high insulation resistance, mercury wetted reed relays. These relays feature low and very stable contact resistance. |

| High speed mercury wetted reed relays |
|
|
| Mercury wetted reed switches used in general purpose mercury wetted reed relays, have timing characteristics varying as a function of switching frequency. This is due to their construction. For example, at 10 to 100Hz switching frequency the operate time ranges from 1 to 3 msec, while at frequencies over 100Hz its operate time will still increase, until erroneous operation occurs. By developing a new type of mercury wetted reed switch with a unique internal construction, we have been able to reduce these operate time variations by more than 50%, when compared to a standard mercury wetted reed switch. In high speed mercury wetted reed relays, the operate time is only 1.1 msec for switching frequency range of 10 to 100Hz; at higher speeds it is nearly equivalent to that of dry reed relays. |
