Product Reviews

Pickering Electronics introduces its reed relay. The switching high voltages, low thermal voltages, triggering directly by CMOS ICs and switching high frequency signals are among the characteristics and application fields of the relay. They are

Available in SMD package, the single-in-line (SIL) and dual in-line package (DIP) as well as other common housing forms. Based at the soft center technology on all relays, a soft inner material is used to minimize the mechanical stress of the reed switch. In addition, the coil bobbin for higher without contact life and reliable contact resistance provides. Pickering Electronics manufactures its winding disembodied coils in a fully automated process that ensures consistent quality and repeatability.

The coil bobbin without increasing the winding window. This has the following advantages: a higher magnetic drive and a better magnetic coupling due to the higher efficiency of the internal windings with smaller diameter (more turns per ohm). The number of ampere-turns (AW) is greater – the sensitivity of the reed relay is often provided in ampere-turns (AW). A review with 15 AW is a double sensitivity to a 30 AW.

As the 30-AW-switch requires a higher magnetic drive, it also has a higher restoring force, which describes the ability to contact to open, when the coil is turned off. This could Pickering Electronics the life of the reed switch often increase.

The reed relay series 117 are particularly suitable for applications that require high density mounting such as ATE switching matrices or multiplexers. They are available in versions for 3 V and 5 V and as a one or two-pole NO (1 Form A / 2 Form A) available. Like all single-line series are built in soft-center technology.

The change-over contact-type of Series 113 is a small SIL version with changeover contacts (1 Form C). The magnetically shielded relays require a board area of ​​3.8 x 12.7 mm (0,15 x 0.5 inches). The switching power is specified at 3 W and like all single inline constructed series of Pickering Electronics in soft-center technology.

The Guide Reed Relay Mate Pickering Electronics provides detailed insights into the reed relay technique. He describes how reed relays are constructed, what types there are, how they work and what parameters influence their function. He assisted in the selection of the correct relay type and compares reed relay with another relay technologies. Finally, it provides information on the correct control and placement of reed relays. The reed relay Mate Guide is available for free on the website of Pickering Electronics as a PDF or can be ordered as gedrucke version.
