Visit Booth PD76, September 13–15, 2023, BIEC, Bengaluru.
September 2023, Clacton-on-Sea, UK: Pickering Electronics, the leading high performance reed relay manufacturer, will be exhibiting its newly-introduced high temperature, high voltage single-in-line Series 104HT at Productronica India, on Booth PD76, 13–15 September 2023, taking place in BIEC, Bengaluru.
The Series 104HT is capable of functioning in environments with temperatures as high as 125°C and can even reach up to 150°C if chosen as an extra option during the building process. It belongs to Pickering’s family of miniature high-voltage reed relays, which come in the SIL package and are spaced at a 6.35mm (0.25in) pitch, providing a stand-off voltage capacity of up to 4kV.
Pickering’s Series 104 reed relays are available in various configurations, including 1 Form A, 2 Form A & 1 Form B. Coil options comprise of 5, 12, or 24V, with an optional internal diode protection. Even higher voltage ratings are available on special order. Mercury wetted devices are also available for applications where bounce free switching is required. These are rated at 1500V DC minimum stand-off, 500V DC switching at up to 50W.
The company will also be showcasing other high voltage reed relays, including the 67ES/68ES SIL/SIP reed relay families. Series 67 and 68 relays feature former-less coils which means that they can be housed in a smaller package than is usual for this type of device, measuring 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 – up to 200W – in the Pickering portfolio. Series 68 devices have PCB connections to coil and flying leads to the switch which isolates high voltage from the PCB.
Electrostatic screening protection is also available for the Series 104 and Series 67 and 68 relays. This 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 problems caused by magnetic interaction when devices are closely stacked.
Commented Kevin Mallett, Technical Specialist at Pickering Electronics: “Pickering continuously looks to improve our product offering. The market in India is vibrant and we expect to see interest at Productronica from diverse sectors such as mixed signal semiconductor testers, high-end cable testers, backplane testers, medical electronics, electric vehicles, solar energy and high voltage instrumentation.
