Using only the highest quality materials, Pickering Electronics manufactures reed relays for instrumentation and ATE, high voltage switching, low thermal EMF, direct drive from CMOS, RF switching and other specialist applications. The company will be demonstrating its portfolio in booth #529 at Designcon USA 2015 Santa Clara Convention Center, 28th to 29th January.

Pickering Electronics’ 117 series reed relays suit very high density applications such as ATE switching matrices or multiplexers. They are available in 3 and 5V, 1 Form A and 2 Form A variants.

The 113 series changeover single-in-line reed relay is Pickering Electronics’ smallest changeover. They require a board area of only 3.x12.7mm (0.15x.025”). The magnetically screened devices have a 3W rating.

Pickering Electronics will also highlight reed relays for high voltage applications.

All reed relays are constructed using Pickering’s SoftCenter technology, which uses a soft inner material to reduce stresses on the reed switch. Former-less coil winding enables a longer contact life and more reliable contact resistance. The former-less coils are manufactured using a fully automated process that provides consistent output quality and repeatability.

Former-less coil winding

Former-less winding greatly increases the winding ‘window’, providing a much higher magnetic drive level and better magnetic coupling as the smaller diameter of the inner turns are more efficient (more turns per Ohm). The number of Ampere Turns (AT) is also increased. Because the 30AT switch needs more magnetic drive there is much more ‘restoring force’, which is the ability to open when the coil drive is turned off. This extends the working life of the reed switch.
