High voltage relays available for up to 10kV
Pickering Electronics have expanded their reed relay range to include the series 67 and 68, suitable for high voltage applications. The relays are available for up to 10kV stand-off and switching up to 7.5kV, with an option of either PCB or flying lead switch connections. The relays are suitable for high voltage transformer and cable test and some electro-medical applications such as defibrillators.
The unusual package design does present some interesting packing possibilities for high density applications as well, such as multiplexers and matrices in instrumentation and test systems. 5, 12 and 24V coils are available as standard and other voltages can be supplied to special order, as can variations in the lead length of the series 68 range.
Similar in specification to the long established Pickering series 60/65, these relays are constructed using a lead frame with pins in a single-in-line format. The use of former-less coils dispenses with the more usual coil supporting bobbin, allowing a smaller package than similar rated devices. All recent style Pickering reed relays also have full magnetic screening which permits side by side operations, allowing for higher packing densities.
