Medical equipment ranging from mobility equipment and high voltage generators to portable devices require switching technology that is highly reliable.
Most power and electric mobility equipment have moving parts in which a start and end position must be detected in order to switch the unit on and off.
A reed sensor and permanent magnet is used in these applications. These reed sensors are hermetically sealed in a rugged package making them a durable sensing option in many mobility equipment applications.
Reed Relays are used in many types of medical equipment that require high current and/or high voltage. Equipment such an electrosurgical generator requires a high voltage relay to aid in regulating the right amount of current used to cauterize vessels during surgery. Similar equipment may use RF energy combined with saline to seal off vessels therefore high frequency relays would provide a better solution.

In portable devices it is equally important to utilize a switch that is ultra miniature and one that consumes the least amount of power. Reed switches and sensors consume no power in their normally open state.
