HIGH VOLTAGE RELAYS
New Series 67 1 Form C High Voltage PCB Relay
• PCB Mounting with option of flying lead switch connections
• Robust tungsten plated vacuum switches
• Plastic package with internal mu-metal magnetic screen
• Ideal for cable and transformer test or other high voltage applications
Pickering Electronics are pleased to announce the new changeover 1 Form C version of our popular Series 67 high voltage PCB relay that saves space and makes design simple.
In applications where high voltage signals need to be routed to alternate points, polarity reversing, capacitor charge or discharge for example, a high voltage Changeover relay (SPDT/Form C) would be the ideal solution. These are often implemented using two Normally Open (SPST/Form A) high voltage relays, by ensuring that one switch is always opened before the second switch is closed. This requires twice the PCB area and can cause complex driving issues. Also, if either of the SPST relays sticks then there is risk of unintentionally shorting signals. Pickering’s new 67-1-C high voltage reed relay guarantees break-before-make operation in a single, compact part.
Rated at up to 5kV stand-off, 2.5kV switching at 100W (max), the new Series 67 changeover relays measure just 58.4 x 12.6mm – the same size as a standard Series 67 relay – and are available with 5V, 12V or 24V coils. Devices feature PCB connections to switch and coil. Like many Pickering reed relays, the Series 67 parts benefit from internal EMI screening and SoftCenter™ construction. The fully-encapsulated, single-in-line relays employ tungsten-plated contacts. Optional flying leads are available for high voltage connections.
Interactive datasheets revealed – packed with more information – clear and easy to read
Pickering Electronics, the reed relay company which has pioneered miniaturization and high performance for over 50 years, has completely revamped the datasheets of its entire range of reed relays, providing more information in a clearer format with interactive links to further useful content.
New information includes additional environmental specs, mechanical characteristics and relay weights, plus RF plots for coaxial relays, showing VSWR, isolation and insertion loss. Instead of being ‘squashed’ onto two pages – a legacy of printed datasheets – the specifications and relay details are more clearly laid out, especially the mechanical drawings.
The new designed-for-digital datasheets include interactive links to relevant technical applications information and content, including a summary document entitled ‘10 key benefits of Pickering Reed Relays’ and a comparison table to similar products from Pickering.
Comments Pickering CEO Keith Moore: “It’s easy to overlook so-called ‘simple’ components such as reed relays, so we decided to make all our experience available to designers as easily as possible, so they make the correct choice.”

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. Pickering Electronics is part of the privately-owned Pickering Group; made up of three electronics manufacturers, including Pickering Interfaces who design and manufacture modular signal switching and simulation products, and Pickering Connect who design and manufacture cables and connectors.
High Voltage Mini-SIL
Single-in-Line SIL/SIP Reed Relay
- Smallest high voltage reed relay currently available
- Switching up to 0.7 Amps, 10 Watts
- Choice of 3, 5 or 12 Volt coils with optional internal diode
- 1 Form A (Energize to make) SPST N.O. configuration
- Internal mu-metal magnetic screen allows side by side stacking without magnetic interaction
- Unique SoftCenter® construction
- 100% tested for dynamic contact resistance
- Highest quality vacuumed, sputtered ruthenium reed switches
- Ideal for cable testers, mixed signal/semiconductor testers, backplane testers, high voltage instrumentation, in-circuit test equipment or other applications where high voltage is required.
Pickering Electronics is pleased to announce the new Series 131. Housed in the miniature SIL/SIP package, new Series 131 reed relays have a footprint of just 12.5mm x 3.7mm and a height of 6.6mm and deliver a minimum stand-off of 1500V.
Featuring a choice of 3, 5 or 12 volt coils, with optional internal diode, Series 131 reed relays are available in the 1 Form A (energize to make) SPST N.O. configuration, and can switch up to 0.7 amps, 10 watts. Devices are ideal for cable testers, mixed signal/semiconductor testers, backplane testers, high voltage instrumentation, in-circuit test equipment or other HV applications. The vacuumed, sputtered ruthenium reed switches have a superb low level performance also, which makes them an ideal choice where a wide range of signals are involved.
The range is based on the long established Series 113 style of plastic package with an internal mu-metal magnetic screen which allows high packing density and are made using Pickering’s SoftCenter® construction.
ULTRA-HIGH DENSITY 4MM REED RELAY
- Stacking on a 4mm x 4mm pitch, with a profile height of just 12.5mm
- Switching at 10 Watts, 0.5 Amp
- Choice of 3 or 5 Volt coils
- 1 Form A (SPST N.O.) Energize to make
- Fast operate times – typically 150µs or less
- Suitable for high speed test, A.T.E. switching systems and
semiconductor test systems
Pickering Electronics is pleased to announce the new 10W-rated reed relay to our successful 4mm product family which features devices that occupy a PCB footprint of only 4mm x 4mm, facilitating the highest packing density currently available.
Fast operate and release times, typically 150 μs or less, make the Series 122 relays ideal for high speed test systems such as A.T.E. switching matrices or multiplexers.
The 1 Form A (SPST) Normally Open (NO) devices feature high-quality, instrumentation-grade sputtered-ruthenium switches with internal mu-metal magnetic screening to avoid the risk of magnetic interaction issues in densely-packed applications.
Devices have an insulation resistance of greater than 1012Ω and are 100%-tested for dynamic contact resistance to guarantee performance.
For ease of servicing/replacement, relays maybe socketed using SMD or through-hole sockets. However, care must be taken to mitigate the risk of affecting contact resistance integrity.
