The Series 104 is a single-in-line reed relay with an internal mu-metal magnetic screen for stacking, available in Form A or Form B configurations. The 104-1-A-5/1 variant features a single Form A dry switch with 1000 V d.c. stand-off and 500 V d.c. switching at 10 W, a 5 V coil, and a pin configuration of 1-3-5-7. It measures 1.14 in (29 mm) in length and 0.49 in (12.5 mm) in height, with a 0.25 in pitch. The coil resistance is 375 Ω, initial contact resistance is 0.15 Ω, and insulation resistance exceeds 10ⁱ Ω. Operate time is 1.0 ms, release time is 0.3 ms, and life expectancy is 10⁸ operations under low-load conditions. The relay must be mounted with pin 1 uppermost.
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.s
