Pickering Enhances Power Ratings for Popular Reed Relays, Expanding High-Spec Options
Pickering has increased the power ratings for four of their popular relay series, the 112, 113, 116, and 122 Series, by 50-100%. This expansion provides customers with higher-spec options for reed relays.
Pickering Electronics, a top producer of high-performance reed relays, has raised the power ratings of four of its most popular relay series. This includes Series 112, 113, 116, and the ultra-high density 4mm2 Series 122. This update provides engineers with more choices for higher switching specifications without requiring additional PCB space. This enhancement is a part of the company's commitment to continuous innovation and product improvement. The increased power ratings expand the already wide range of switching options available to customers. With a wide selection of relay versions available, as well as customizable options and bespoke relays for specific application needs, engineers now have more flexibility than ever before.
The Series 112 single-in-line (SIL) reed relays, which have a compact size of 0.15 inches by 0.4 inches, now come with a new general purpose switch option that can handle up to 20 Watts (15 W for the 3 V coil version) at 1 Amp switching current. The relay's small size is achieved by mounting the reed switch diagonally within the package. These relays are suitable for high-density card-based systems like VME, VXI, CompactPCI, and PXI. The high-quality ruthenium switch contacts also make them ideal for automatic test equipment (ATE).
The Series 113 SIL reed relay range has been updated to include new general purpose switch type 1 options. This switch can handle up to 20 Watts (15 W for the 3 V coil version) at 1 Amp switching current, with a carry current of 1 Amp as well. The size of the board area remains small at 0.15 inches (3.8mm) by 0.5 inches (12.7mm). Within this series, there is also the smallest changeover reed relay on the market, rated at 2 Watts (switch type number 3) and suitable for up to 3GHz. Furthermore, the switch type 1 option will now be available in a 2-pole DPST with a 5 V coil, allowing for up to 20 Watts switching at 1 Amp.
The Series 116 relays are designed for applications requiring high-density, such as ATE switching matrices or multiplexers. These relays now come with new general purpose switch type 1 options that can handle up to 20 Watts of power (15 W for the 3 V and 5 V coil versions) at a switching current of 1 Amp, with a carry current of 1 Amp as well. The board area is optimized with 1 Form A (SPST) stacking on a 0.15 inch x 0.27 inch pitch and 2 Form A (DPST) stacking on a 0.15 inch x 0.40 inch pitch. Additionally, the Series 116 will also be available in a 2-pole DPST configuration, with a 5 V coil capable of handling up to 1 Amp and 15 W, or a 12 V coil with up to 20 W switching power.
The Ultra-High Density Series 122 reed relays are designed to be very compact, with a PCB footprint of just 4mm x 4mm. They now come with new general purpose switch type 1 options that can handle up to 15 Watts at 1 Amp switching current, with a 1 Amp carry current. These relays are 12.5mm tall and allow for the highest packing density possible. They use high-quality reed switches and internal mu-metal magnetic screens to reduce magnetic interference when stacked closely together.
Kevin Mallett, a Technical Specialist at Pickering Electronics, mentioned that the power ratings for the new general purpose switch type number 1 options have increased by 50-100% compared to the previous switch type number 2 option. This means that customers can now take advantage of higher switching specification options in four of the company's most popular relay series.
Pickering reed relays are highly reliable because of their superior manufacturing and quality control methods. They use instrumentation-grade sputtered ruthenium contacts instead of the less stable electroplated rhodium found in lower quality reed relays. The formerless coil construction from Pickering increases magnetic efficiency, allowing for the use of less sensitive reed switches which leads to better switching performance and longer lifespan in extreme conditions. Additionally, magnetic mu-metal screening helps prevent issues caused by magnetic interference when relays are placed close together.
Pickering Electronics sets itself apart by thoroughly testing all operating parameters, including dynamic contact wave-shape analysis, to ensure consistency and reliability. They go beyond simple DC testing or batch testing to prevent non-operational devices from being supplied. Pickering Electronics also conducts 100% thermal cycling stress testing during manufacturing, exposing the devices to temperatures ranging from -20°C to +85°C three times. This level of rigorous testing is not commonly seen in other manufacturers, leading to fewer field failures.
