The launch of the latest variant of the Series 104 miniature high voltage reed relay from Pickering is now rated up to 150°C.

Pickering Electronics, a renowned company for its remarkable advancements in reed relay miniaturization and superior performance over the past 50 years, today launched a new high temperature high voltage single-in-line reed relay that can operate at up to 125°C, and can even reach up to 150°C if chosen as an extra option during the building process. Notably, the new Series 104HT relay belongs to a family of miniature high voltage reed relays and is available in the SIL package on a 6.35mm (0.25in) pitch, with a stand-off voltage capability of up to 4kV.

Series 104HT suits a wide range of applications including EVs, solar, HV instrumentation IC testers and more.

“High temperature can significantly affect the performance of reed relays, and many devices are only able to operate at up to 85°C. By designing these devices with increased magnetic drive and using specialist potting materials to sustain insulation resistance, Pickering can now offer reed relays that perform at elevated temperatures, and which can be stored at up to 150ºC.” Said Kevin Mallett, Technical Specialist at Pickering Electronics.

Available Options

The Pickering Series 104 reed relays feature internal mu-metal screening, effectively countering any magnetic interference.

Configuration options include:

• electrostatic shielding
• 1 Form A, 2 Form A & 1 Form B, and can be fitted with coils of either 5, 12 or 24V, with optional internal diode protection
• With four types of dry switches to choose from, these relays are capable of standing off 1.5, 2, 3 or 4 kV DC. The 3 kV and 4 kV versions have been designed with an increased clearance between the switch and coil pins to accommodate the higher voltage.
• If the user requires even higher voltage ratings, Pickering provides a variety of build options, or fully customized designs tailored to meet unique requirements.
• 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.

For users requiring a reliable reed relay that can perform well in high temperature environments, the new Series 104 high temperature, high voltage reed relays are worth considering. Suiting a variety of applications, including mixed signal semiconductor testers, high-end cable testers, backplane testers, medical electronics, electric vehicles, solar energy and high voltage instrumentation.

About Pickering Electronics

Pickering Electronics was formed over 50 years ago to design and manufacture high quality reed relays, intended principally for use in Instrumentation and Test equipment. Today, Pickering’s Single-in-Line (SIL/SIP) range is by far the most developed in the relay industry with devices 25% the size of many competitors. These small SIL/SIP reed relays are sold in high volumes to large ATE and Semiconductor companies throughout the world.

The privately-owned Pickering Group comprises three electronics manufacturers: reed relay company Pickering Electronics; Pickering Interfaces, designers and manufacturers of modular signal switching and simulation products, and Pickering Connect which designs and manufactures cables and connectors.
