The Series 104 is a single-in-line reed relay designed for high-voltage switching applications up to 3 kV DC stand-off. The 104-1-A-12/1D variant features a single Form A (energize to make) dry switch rated for 1000 V DC switching at 10 W, with a 12 V coil and an integrated diode. It has a 0.245 inch pin pitch, measures 1.14 inches in length and 0.49 inches in width, and includes an internal mu-metal magnetic screen for reduced magnetic interaction in stacked arrays. Insulation resistance exceeds 10^12 ohms, with a typical capacitance of 2.5 pF across the open switch and 0.1 pF from switch to coil. Operate time is 1.0 ms maximum, and release time is 0.3 ms. Mercury-wetted versions are available but not applicable to this part. The device must be mounted vertically 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
