Magnetic Reed Switches Offer Sensitivities From 3 to 100 ATStandex Electronics provides magnetic reed switches from 3.7 to 50 mm in both standard designs with exposed leads, and molded, surface mount designs. Manufactured to exacting standards, these magnetic reed switches offer unparalleled sensitivities from 3 to 100 AT. Models are available for dry switching or power switching to 70 VA, and for switching from microvolt levels to 15 VA. Value-added services include DV testing with customer specified loads., custom lead cutting and forming, providing custom magnetic sensitivity ranges (for both pull-in and drop-out), and detail application assistance.

The reed switches are ideal for many position sensing, level sensing, and non-contact sensing applications, including use within hearing aids, pill cams, and other medical devices.

The GR150 is the smallest magnetic reed switch in the world, measuring just 3.7 mm in length. In addition to being able to fit in very small spaces, the GR150 also maintains a very narrow sensitivity range. With a magnetic sensitivity of 2-4 ampere turns (AT), typical operating time of 0.2 milliseconds (typical) and a release time of 0.1 milliseconds (typical), this professional grade ultra miniature reed switch is ideal for very demanding applications, such as within hearing aids and pill cams.

Designed for applications where the available magnetic field is extremely low and/or the space limitations are a major design factor, the GR150 functions as a non-contact position sensor. It features PGM alloy contacts and has a power rating of 1 VA maximum. A switching current (Max) of 0.05 Amp DC is standard, as is a carry current rating (max) of 0.5 Amp DC. Boasting an operating range of -40 to 125°C, the GR150 is well suited for use wherever small size and sensitivity are required for non-contact position sensing applications.
