The Series 104 is a single-in-line reed relay with an internal mu-metal magnetic screen for minimizing magnetic interaction in stacked configurations. The 104-1-B-12/1D variant is a Form B (energize to break) relay with a 12 V coil, rated for 1000 V d.c. stand-off and 500 V d.c. switching at 10 W. It has a maximum contact resistance of 0.20 Ω, insulation resistance greater than 10¹² Ω, and operate and release times of 1.0 ms and 0.3 ms respectively. The relay dimensions are 1.14 in (29 mm) long and 0.49 in (12.5 mm) high, with a 0.25 in pitch. It includes an integrated flyback diode. Mercury wetted and higher voltage dry switch options are available in the series, but this variant uses a dry switch. Mounting must ensure correct coil polarity due to the internal diode.
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
