Ultra-high-density single-pole relays target high-speed systems

By Heather Hamilton, contributing writer

Electronics, a manufacturer of reed relays for use in instrumentation and test
equipment, recently launched what it claims is the smallest through-hole reed
relay in the industry. The new Series 124 offers
ultra-high-density 4-mm2 reed relays that stack on a 4 × 4-mm pitch.
The relays also boast a low profile at 9.5 mm high.

124 relays are available in 1 Form A with 3-V or 5-V coil options. The relays
feature a sputtered ruthenium switch rated at 5 V, 0.5 A like Pickering’s
Series 111, 111P, and 117 relays, but they are placed vertically in the package
to allow for higher density.

The new series features a fast operate time,
typically 80 µs. The fast operate time, along with its high density, makes it
well-suited for high-density applications like automatic test equipment (ATE)
and semiconductor switching matrices or multiplexers.

This is Pickering’s second series of
ultra-high-density single-pole relays. Devices in the Series 120 were released last
year. They were rated up to 1.0 A at 20 W with a higher profile height.
