Pickering Electronics has extended its 4mm product family with the Series 122 reed relay.

Used in high speed test systems, occupying a PCB footprint of 4x4mm, Pickering claims the relay provides the highest packing density currently available. The relay measures 12.5m

m in height and can operate from 3V or 5V. Its contacts are rated with a switching current of 0.5A at 10W.

Featuring instrumentation-grade sputtered-ruthenium switches, the 1 form A (SPST) normally open energize-to-make devices have plastic packages with internal mu-metal magnetic screening to avoid cross-interference and ‘false’ switching in densely packed applications.

Devices are tested for dynamic contact resistance and have an insulation resistance of greater than 10¹²Ω.

The relays may be socketed using SMD or through-hole sockets. However, care must be taken to mitigate the risk of affecting contact resistance integrity.

The Series 122 reed relay is suitable for test systems such as A.T.E. switching matrices or multiplexers, Pickering says.

Keith Moore, CEO at Pickering Electronics says “We launched our first 4mm2TM product, the Series 120, with a switching rating of up to 1A at 20W and a height of 15.5mm. Last year, the Series 124 reduced this profile to 9.5mm but with a slightly lower rating of 0.5A at 5W. We can now provide customers with the new Series 122 device which fills the gap in our product range and offers the flexibility required to design in a product that exactly matches their requirements.”

Pickering will be showing the Series 122 relays at Productronica in Munich, 12-15 November.

 Products including world’s smallest and high voltage reed relays now available for immediate shipment from U.S. distributor

Pickering, the reed relay company which has pioneered miniaturization and high performance for over 50 years, has signed a distribution deal with Testco, the specialist distributor of  passive, electromechanical and interconnect components based in Sunnyvale, CA. This means that Pickering’s large range of reed relays for A.T.E. switching and semiconductor test is now available and supported by the distributor across North America.

Included in the inventory of Pickering’s reed relays that are held by Testco for immediate shipment are the 4mm^2TM product family which feature industry’s smallest footprint – 4mm x 4mm. Within the family, Series 120 devices have a switching rating of up to 1A at 20W and a height of 15.5mm, Series 122 relays measure 12.5mm in height and are rated with a switching current of 0.5A at 10W, and Series 124 products which feature industry’s lowest profile – 9.5mm – and a rating of 0.5A at 5W. Pickering’s range of high voltage reed relays will also be offered from stock.

Commented Keith Moore, CEO, The Pickering Group: “We have been impressed by Testco’s expertise and their ability to offer creative supply chain solutions to meet the requirements of customers, including flexible blanket orders, bonded inventory, consolidated shipments, and annual pricing programs. We are delighted to add Testco to our network.”

Added Jeff Meyer, President at Testco: “Pickering is known as a leader in relay technology having regularly introduced product innovations such as screening to ensure relays can be closely packed together, and ongoing miniaturization programs. We are sure that our customers will benefit from the advantages that Pickering’s products offer and look forward to a long and successful partnership.”

July 9 – 11, 2019, Booth 5656 Moscone Center, San Francisco

Pickering Electronics, the reed relay company which has pioneered miniaturization and high performance for over 50 years, will debut  a new 10W member of its successful 4mm^2TM product family at the upcoming Semicon West exhibition. Like other reed relays in the family, new Series 122 devices occupy a PCB footprint of only 4mm x 4mm, facilitating the highest packing density currently available. Series 122 relays measure 12.5mm in height and are rated with a switching current of 0.5A at 10W. 3V and 5V coils are available.

Fast operate and release times, typically 150 μs or less, make 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) Energize-to-make devices feature highest-quality, instrumentation-grade sputtered-ruthenium switches and plastic packages 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.

Other members of the family include the Series 120 which has a switching rating of up to 1A at 20W and a height of 15.5mm and the Series 124 which has a lower 9.5mm profile and a slightly lower rating of 0.5A at 5W.

Pickering Electronics will be sharing Booth 5656 with its sister company, Pickering Interfaces which will showcase its latest high-density PXI and Ethernet LXI Switching & Simulation Solutions along with their Signal Routing Software.

Series 117 reed relays offer high performance and reliability at a competitive price point 

Pickering Electronics, the reed relay company which has pioneered miniaturisation and high performance for over 50 years, has announced that its two-pole single-in-line (SIL) 117 series reed relay is being extensively used in large switching matrixes due to a combination of small size, performance and cost.

All models in the 117 series are rated at 100V and can a carry up to 0.5A signal current and switch 5W of signal power. Versions are available that support 3V coil drives for systems working at low supply voltages. The two pole version has a footprint of just 10.16mm x 3.81mm, while the single pole device occupies just 6.86mm x 3.81mm – just 38% and 26% respectively of the board area required for industry-standard SIL relays.

The 117 series reed relays are constructed using Pickering Electronics SoftCenter® technology with an integral magnetic screen, ensuring that the relays exhibit excellent reliability and avoid magnetic interaction issues when closely packed together. Devices are also priced very competitively, and it is this combination of attributes – size, performance and price – that suit them so well for use in high volumes in PXI and other switching matrix solutions.

Pickering Interfaces is a provider of such test and measurement solutions and uses 117 series reed relays extensively in many of its products, including the BRIC™ high-density, fully scalable, integrated PXI large matrix modules with built-in high-performance analogue bus. Available in 2, 4, or 8 slot 3U versions, rated at up to 150V, 1A and 20W, these units rely on Series 117 high-reliability instrument- grade reed relays to deliver the performance required by demanding applications in defense, automotive and semiconductor manufacturing industries. Comments Pickering Interfaces’ CEO, Keith Moore: “We have been able to maximise switches density of our products without compromising reliability or performance in large part because of the benefits offered by the Series 117 relay family.”
