These miniature SMD reed sensors are designed for low power, high speed switching applications, and have a cost advantage over the standard size SMD reed sensor. As they are molded with pre-flattened leads, no shock is transferred into the device when SMD formation takes place. Various activating distances are available depending on the magnet and the AT band used. The sensors are tested 100% for Operate AT, Release AT, Static Contact Resistance and Variable Contact Resistance before packing. Our products are completely Lead-free and conform to the RoHS directive. Click to download this product data sheet as a PDF.
This reed sensor is suitable for use in the following applications and in many others: cellular phones and PDAs, weather proof electronics, electric tooth brushes, automobiles with electronic keys, digital pressure gauges, wind vanes, survival rafts and ELTs, pedometers, model gliders…

A few examples of magnet actuation are shown above. Being an omnipolar device, this sensor can be actuated with either a north pole or a south pole or both. Choosing the right AT band, magnet strength, and operating axis, will restrict the number of operates and releases to one.
