A latching reed sensor is an extremely low power solution. These work very well in battery powered devices and other power critical applications. Latching or bi-stable sensors use magnetic biasing to open and close their contacts. The sensor contains one or more internal reed switches and/or permanent magnets. The internal permanent magnet moves the reed switch contacts closer together. But still the contacts remain in the open state. Because the magnet is only partially magnetized. While an external magnet opens and closes the switch by reversing the magnetic field. Hence the latching function. The contacts remain in their normally open or closed state until the magnetic field is changes yet again. The latching function can get tricky! So you'll need work with our latching sensor experts. They'll design a solution according to your specific application. Learn more...

Our miniature reed sensor series have glass lengths ranging from 7-14mm. Aside from being miniature, SMD sensors draw no power in their normally open state. And with power critical applications on the rise. It's no wonder reed sensors are some of the most sought after in the industry. Furthermore, their miniature size make them ideal in critical areas for miniaturization. Which are the electronic and semiconductor equipment testing market and medical devices. But they are also heavily used in test equipment, telecommunications, security, automotive, appliances, industrial, among other markets. Miniature reed sensors come in a variety of switching characteristics. Such as close differential, high current, mercury, high performance and even SPDT single pole double throw changeover contacts.
The MK33 series reed sensor is a bare glass sensor engineered with a new lead design, providing stability and optimum coplanarity. The unique barrel lead design provides superb solderability and self-alignment to the pads for easy pick and place. Choose from 2 different switch models: the ultraminiature 10mm MK33-87 version or the 14mm automotive-grade MK33-66, capable of switching 200 VDC. Each features an extremely low-profile construction, ideal for applications requiring small footprint in printed circuit board (PCB) assemblies. Their tiny footprint allows the MK33 series to be mounted in a tight reed switch ladder array, for multi-point and continuous liquid level monitoring applications. Supplied in tape and reel according to IEC 60286- 3.
