Pickering Electronics offers optional electrostatic shielding on its 10kV stand-off Series 67/68 SIL/SIP reed relay families. Electrostatic screening guards against noise which may otherwise emerge between the coil drive and high-voltage circuits. This new screening is in addition to its internal mu-metal screen, eradicating magnetic interaction when devices are closely stacked.
These series of high voltage reed relays are created using a lead frame in a Single-in-Line format and provide former-less coils, which indicates that they can be housed in a
smaller package than is typical for this type of device, measuring just 58.4mm x 12.6mm x 14.5mm. Series 67 relays offer PCB connections to switch and coil and supply the highest power switch capability in the company's portfolio – up to 200W. Series 68 devices include PCB connections to coil and flying leads to the switch, keeping 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); and 5, 12 or 24V coils are provided with the choice of an internal diode across the coil connections.
"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," commented Kevin Mallett, technical specialist at Pickering Electronics.
