The Series 63 high voltage dry reed relay, part number 63-1-A-12/3, is a printed circuit board mounting relay with a 15kV stand-off voltage and 12.5kV switching capability at up to 50 Watts. It features a Form A (energize to make) contact, tungsten-plated contacts for long life, and a 12V nominal coil voltage with 150 Ω coil resistance. The relay has a 3 pF capacitance across the open switch and 0.15 pF across the closed switch, with an operate time of 3 ms and release time of 2 ms. It operates within a standard temperature range of -20 to +85 °C and is fully encapsulated. Dimensions are 2.50 in. (63.5 mm) long, 0.84 in. (21.3 mm) wide, and 0.75 in. (19.1 mm) high, with push-on high voltage connections on the top face.
The Series 62 and 63 ranges of high voltage reed relays feature push-on terminals and are supplied complete with the appropriate connectors and insulating boots.
They are available for up to 15kV stand-off, 12.5kV switching at 50 Watts maximum. Tungsten plated contacts ensure a long and reliable life.
Both Form A (energize to make) and Form B (energize to break) configurations are available and it is usually possible to achieve a Form C (change-over) function by using a Form A and a Form B type together.
These relays feature an internal mu-metal magnetic screen which permits the Form A (energize to make) versions to be mouted side by side. Special versions can be manufactured with an electrostatic screen and/or earth connection to the magnetic screen. This can often be useful where EMC problems are encountered, please contact our technical sales office.
Form B types are magnetically biased and should not be mounted directly onto ferrous metal chassis or less than 1 inch (25mm) away from other relays as the coil operating voltage characteristics will be altered due to magnetic interaction. The coils of Form B relays are polarity sensitive, the positive connection is identified by a red spot.
5, 12, and 24 volt coils are available as standard other voltages can be supplied to special order.
