The Series 63 high voltage dry reed relay, model 63-1-A-5/3, is a printed circuit board mountable relay with a Form A (energize to make) contact configuration, offering 5 kV stand-off and 3.5 kV switching capability at up to 50 Watts. It features a 5 V coil with 50 Ω resistance, tungsten-plated contacts, and a typical contact capacitance of 3 pF across the open switch. The relay measures 63.5 mm in length, 25.4 mm in width, and 21.3 mm in height, including the push-on high voltage connections on the top face. It operates within a temperature range of -20 to +85 °C and has a typical operate time of 3 ms. The device is fully encapsulated, with a nylon insulating boot and clear polarity indication for coil connections.
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.
