FEATURES
The Series 104 is a range of Single-In-Line reed relays intended for
voltages that are beyond the capabilities of conventional SIL reed relays.
They are ideal for such applications as transformer or cable testing or any
other automatic test equipment where high voltages are involved.
Where mains voltages are switched, for example to control and isolate
S.C.R. or triac gates, they are an ideal choice.
One or two Form A (energize to make) or one Form B (energize to
break) confi gurations are available.
The range features an internal mu-metal screen to eliminate problems
that would otherwise be experienced due to magnetic interaction when
they are closely stacked.
Three types of dry switches are available, capable of standing-off 1,
1.5 or 3kV d.c. The 3kV version has an increased clearance between
the switch and coil pins to accomodate the higher voltage. Even higher
voltage ratings are available to special order, please contact our sales
offi ce for further information.
Mercury wetted devices are also available for applications where bounce
free switching is required. These are rated at 1500 volts d.c. stand-off,
500 volts d.c. switching at up to 50 watts.
