Clacton-on-Sea, UK:   Pickering Electronics now offers optional electrostatic shielding for its 10kV stand-off Series 67/68 SIL/SIP reed relay families. Electrostatic screening protects against noise that can otherwise occur between the coil drive and high-voltage circuits. This new screening is in addition to Pickering’s internal mu-metal screen. It eliminates magnetic interaction when devices are closely stacked.

Series 67 and 68 high voltage reed relays are constructed using a leadframe in a Single-in-Line format. Additionally, it features former-less coils which means that they can be housed in a smaller package than is usual for this type of device. The package measures just 58.4 x 12.6 x 14.5mm.

Series 67 relays, along with electrostatic shielding, feature PCB connections to switch and coil and provide the highest power switch capability in the Pickering portfolio – up to 200W. Moreover, Series 68 devices have PCB connections to coil and flying leads to the switch which keeps high voltage away from the PCB.

Configurations include:
  • 1 Form A SPST up to 10kV stand-off, 7.5kV switching at 50W (max);
  • 1 Form A SPST up to 8kV stand-off, 6kV switching at 200W (max);
  • 1 Form C SPDT up to 5kV stand-off, 2.5kV switching at 100W (max);
  • 5, 12 or 24V coils are available with the option of an internal diode across the coil connections

Commented Kevin Mallett, Technical Specialist at Pickering Electronics: “Pickering continuously looks to improve our product offering. Electrostatic screening adds a new level of protection, ensuring our relay families provide the optimum performance for high voltage applications.”
