Electrostatic shielding improves performance for reed relays

The new electrostatic shielding option for reed relays from Pickering eliminates noise issues in tightly stacked designs

Pickering Electronics is now offering optional electrostatic shielding for its 10kV stand-off Series 67/68 SIL/SIP reed relay families. Electrostatic screening protects against noise which can otherwise occur between the coil drive and high voltage circuits. This new screening is in addition to Pickering’s internal mu-metal screen which 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 and feature former-less coils which means that they can be housed in a
smaller package than is usual for this type of device, that measures just 58.4 x 12.6 x 14.5mm. Series 67 relays feature PCB connections to switch and coil and provide the highest power switch capability in the Pickering portfolio – up to 200W. Series 68 devices have PCB connections to coil and flying leads to the switch which keeps high voltage away from the PCB.

Kevin Mallett, Technical Specialist at Pickering Electronics says that electrostatic screening adds a new level of protection, ensuring the available relays provide optimum performance for high voltage applications.
