Pickering Company launches its latest high-power reed relay with a rated power of up to 80W

Pickering Electronics, a leading manufacturer of high-performance reed relays, announced in March 2024 the launch of its latest high-power reed relays with a rated power of up to 80W, which can be tightly arranged at 0.25 inch intervals and are called the 144 series. Single in line package (SIP) reed relay provides a switching current of up to 2A and an output power of up to 60W; Or 1A switch current, power up to 80W, continuous carrying current up to 3A. In addition, it also has high voltage resistance, with a switch voltage of up to 1000VDC and a withstand voltage of up to 3kV at a power level of 10W.

The 144 series is the smallest miniature SIP reed relay in Pickering's products with a rated power of up to 80 watts. It combines the ability to effectively switch between higher power and special low-level performance, making it an ideal choice for high-power and low-level switches. Very suitable for mixed signal semiconductor testing machines, photovoltaic efficiency monitoring systems, testing of new energy vehicles and charging stations, mining gas analysis, medical electronics, online testing equipment, and high-voltage instruments and meters. The 144 series is more environmentally friendly than mercury tongue spring relays and has superior performance compared to electromagnetic relays. Its low-level performance and high isolation performance have significant advantages.

Kevin Mallett, a technical expert at Pickering Electronics in the UK, pointed out that the 144 series has a very high rated power and is more environmentally friendly. Although dry springs may not achieve bounce free operation, their more environmentally friendly structure is very helpful for sustainable development. Compared with small electromagnetic relays (EMR), reed relays perform well in performance and isolation, significantly improving application efficiency and reliability. Reed relays have faster switching speeds and longer mechanical life, further enhancing product competitiveness.

With a maximum switching voltage of 10W, 1000VDC, and 2 or 3kV DC withstand voltage options, Pickering's 144 series relays are suitable for a variety of applications. The 3kV version has increased the gap between the switch and coil pins to accommodate higher voltages. 1 Form A, 2 Form A, and 1 Form B configurations are available, with coil options of 5 V, 12 V, or 24 V and optional internal diode protection. According to the requirements, other construction options can also be selected, including multiple pin configurations. Pickering also provides customized load testing to ensure that components strictly meet technical specifications and user needs.

The characteristic of a reed relay is the use of a vacuum reed switch, with contacts sealed inside glass tubes, which has more advantages compared to electromagnetic relays. This design provides a protective barrier that can prevent the impact of environmental factors such as dust, moisture, and other pollutants. On the contrary, electromagnetic relays are structurally open, with their internal components exposed to the outside. Over time, exposure to high humidity or air pollutants may lead to oxidation issues and severely affect low-level performance. At the same time, reed relays are easy to maintain their performance and reliability over the long term, making them the preferred choice in applications where durability and lifespan are crucial.

With excellent manufacturing processes and strict quality control, Pickering's reed relays have high reliability. These relays use instrument grade sputtered ruthenium contacts instead of electroplated rhodium. Combining Pickering's SoftCenter ™ Technology greatly reduces the internal stress of the reed switch, thereby extending its service life and maintaining contact resistance stability. The boneless coil structure makes such devices smaller than typical relays and eliminates interference caused by magnetic interactions during stacking through magnetic shielding technology.
