Standex Electronics introduces 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, in pill cams, flip or slide phones, laptop computers, and more.
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°C to +125°C, the GR150 is well suited for use wherever small size and sensitivity are required for non-contact position sensing applications.
Designed primarily to address the needs of medical device manufacturers for use within hearing aids, pill cams and other surgical and medical devices, the GR150 is also applicable for other markets such as consumer electronics, industrial applications, military and aerospace, and more.
