MK31 Series SMD Reed Sensor for Low Power Applications

The MK31 Series performs better than all other surface mount reed sensors in its size class! And with the current push towards smaller electronic designs, both performance and size are paramount. Performance in reed switch technology refers to both physical durability and switching life. Reed switch technology has a reputation for being high quality. In contrast, mechanical switches have a history for early failures due to worn parts and/or environmental contaminants.

First, the MK31 series is ultraminiature measuring only L6.4mm x H1.95mm x W2.2mm. In fact, it’s 20% smaller than the competitor’s part. Also, next to our MK24 series it’s the smallest reed sensor on the market. Though it’s small, this sensor packs a powerful performance. Capable of switching a minimum of 50 million reliable operations.

In addition to its long switching life, this tiny sensor is physically robust! It has no wearing parts and is environmentally rugged inside and out. Inside this sensor is a hermetically sealed reed switch. On the outside, the reed switch is over-molded with an extremely durable thermoset plastic. Furthermore, it’s smooth flat surface and J-lead design make it highly suitable for automatic PCB placement. As well as it’s convenient tape and reel packaging.

Finally and most importantly, the MK31 Series SMD reed sensor uses no external power in its normally open state! This is especially important as power efficiency has become more demanding in today’s electronics.

In summary, the MK31 sensors‘ compact size, physical durability, and low power properties make it the ideal solution in low power and space limited applications. These applications include battery driven and portable devices. Applications in some of these major markets like medical, consumer electronics, metering, and security markets are just a few examples of where the MK31 is a good fit.
