Aus kundenspezifischer Anforderung entsteht das kleinste Hochvolt-Reed-Relais der Branche

Pickering Electronics, das Spezialunternehmen für Reed-Relais und seit über 50 Jahren Pionier auf dem Gebiet der Miniaturisierung und Leistungsfähigkeit, hat ein Hochspannungs-Miniaturrelais für den Einsatz in einem neuen Prüfstand entwickelt, der vom weltweit tätigen Chiphersteller ON Semiconductor entworfen worden ist.

Für Schaltsysteme in der Prüf- und Messtechnik sind Reed-Relais dank der Kompaktheit, des Isolationswiderstandes, der hermetisch gedichteten Kontakte, der kurzen Schaltzeit und der hohen Lebenserwartung der Bauteile, oft die beste Lösung. Für die Entwicklung eines neuen Prüfstands benötige ON Semiconductor als langjähriger Kunde von Pickering ein Reed-Relais mit einer Durchbruchspannung von mindestens 400 V=, das gleichzeitig kompakt genug sein musste, um die hohen Anforderungen in Bezug auf die Packungsdichte zu erfüllen.

Die durch die anspruchsvolleren Spezifikationen erforderlichen Abstände zwischen den einzelnen Relaiskomponenten würden die Gehäusemaße der anderen Miniaturrelais aus dem breit gefächerten Portfolio von Pickering nicht erfüllen können. Aber nach nur sieben Wochen konnte Pickering bereits die ersten Prototypen in einem 6,6 mm hohen Mini-SIP-Gehäuse mit Seitenlängen von 12,5 mm x 3,7 mm und einer Durchbruchspannung von mindestens 1500 V dem Kunden zur Verfügung stellen.

Keith Moore, CEO von Pickering: „Weil Pickering alle Prozesse der Konstruktion und Fertigung von Relais im eigenen Haus durchführt, können wir so schnell und effektiv auf Kundenanfragen wie diese reagieren. Hier ist, wie schon so häufig, aus einer Sonderausführung ein neues Produkt hervorgegangen, und das führen wir jetzt als Series 131 im Sortiment: die kompaktesten Hochvolt-Reed-Relais der Branche.“

Die mit 3 V-, 5 V- oder 12 V-Spule und optionaler Diode erhältlichen Reed-Relais aus der Serie 131 sind als Schließer (SPST NO, Form A) ausgeführt und können bis zu 0,7 A / 10 W schalten. Die Bauteile sind die ideale Wahl für Kabeltester, Mixed-Signal-/Halbleiter-Tester, Backplane-Tester, HV-Messgeräte, In-Circuit-Tester und weitere Hochspannungsanwendungen.

Pickering Electronics fertigt neben der Series 131 auch eine große Auswahl verschiedenster Hochvolt-Reed-Relais im SIL/SIP-Miniaturformat. Die Bauteile aus der Series 119 überzeugen mit Durchbruchspannungen bis 3 kV auf einer Fläche von 15,1 x 3,7 mm (1 Form A) bei einer Höhe 6,6 mm, während die Series 104s bei gleicher Spannungsfestigkeit mit höherer Schaltleistung bis 25 W und höherem Spulenwiderstand bis 3000 Ω in einem Package mit den Maßen 24,1 x 6,3 x 8,2 mm (Schließer) punkten.

series-131-Relay

Pickering Electronics, the reed relay company which has pioneered miniaturization and high performance for over 50 years, has announced that it has developed a miniature high voltage relay for use in a new test rig, designed by globally-renowned chip maker, ON Semiconductor.

In switching systems for test and measurement applications, reed relays are often the best solution thanks to their small size, high isolation resistance, hermetically sealed contacts, fast operate time and long-life expectancy. When developing a new test rig, ON Semiconductor – a long-standing customer of Pickering – identified the need for a reed relay with a stand-off voltage of at least 400VDC, which was also small enough to meet its demanding high switching density requirements.

The internal clearance constraints required by the uprated specs would not fit within the package dimensions of other miniature relays in Pickering’s broad portfolio. However, in just seven weeks, Pickering was able to send first prototypes of a device housed in the mini-SIP package with a footprint of 12.5mm x 3.7mm and a height of 6.6mm able to deliver a minimum stand-off of 1500V.

Comments Keith Moore, Pickering’s CEO: “Because Pickering has all elements of relay design and manufacture in house we are able to respond quickly and effectively to custom requests such as this. In this instance, as so many previously, a special design leads to a new standard product, and so we now offer Series131 devices – industry’s smallest high voltage reed relays.”

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 and other HV applications.

Pickering Electronics also manufactures various other miniature high voltage SIL/SIP reed relays. Series 119 types deliver a stand-off voltage performance of up to 3kV on a footprint of 15.1 x 3.7mm (1 Form A) and a profile of 6.6mm, while Series 104s offer the same high voltage performance but with a higher switching power of up to 25W and a higher coil resistance of up to 3000Ω in a package measuring 24.1 x 6.3 x 8.2mm (1 Form A).

122-10W-Reed-Relay

Reed relays have never been known for high power switching, in fact, high carry currents can seriously affect switch life and reliability due to the very use of reed switches. On the other hand, reed switches allow for very
efficient spatial distribution, taking up minuscule amounts of surface area on your board.

One of the first impressions we’ve had upon opening the samples that Pickering sent us is the extremely neat and tidy packing. Each set of relays came in its own tiny plastic box with clear windows, complete with a
protective layer of sponge and a satisfying “click” when opened and closed. Nothing important for the tests, but a nice touch nevertheless. Pickering has also thrown in a really nice set of literature, including an 80-page product catalog, along with a handy relay look-up chart and a brief relay theory overview booklet.

Reed-Relays-On-Desk

Pickering’s new 120 Series relays have an exceptionally small footprint, with 20 watts of switching power and 3, 5 or 12 Volt coils are the smallest relays of such performance on the market. With a 4mm by 4mm base, they
are almost four times smaller than Pickering’s own 110 series.

The 110 Series have already offered an extremely compact relay solution with great performance. We also loved the fact that it is breadboard friendly and operable directly from TTL logic. This means that it can be
directly incorporated in many existing prototypes without much preparation. The 110 Series and the 120 Series relays have very similar specifications in their datasheets, so we took them to the testing bench to see if any hidden differences lurk beneath.

110-Reed-Relay-In-Box

On our test bench, we’ve assembled a bare bones circuit for bench marking these, mostly looking at their bounce times and operating voltages. We’re quite impressed by their overall performance, in both cases conforming to the listed specs completely. Nevertheless, we found that the 120 series relays have a much more noticeable bounce upon making contact. Where the 110 series relays’ bounce is so subtle that it can easily be mistaken for ringing, the 120 series relays offer an almost textbook example of relay bounce, with unmistakable voltage dips lasting a few hundred microseconds. Another curiosity in this series is the tendency to bounce a lot more on certain frequencies, namely around 314Hz, and in the 610-670Hz range, while at certain other frequencies, the bounce almost completely disappears. This trait is much less noticeable on the 110 Series. As with all reed relays, these are almost completely silent, with a high-pitched, quiet hum emanating at frequencies above 50Hz, raising in pitch with the frequency.

Pickering’s 120 Series is quite susceptible to external magnetic interference, starting with slowing down relay operation to completely jamming it open, but have no trouble being tightly packed and operating next to each other. Pickering’s 110 Series is a little less prone to external magnetism, but with a strong magnetic source closer than 5cm from the device, the relay tends to lock up.

We’ve certainly liked these relays, as they offer great speed and miniscule bounce times with an extremely
small footprint, for uses where this precision matters and the carry currents and voltages are low.
