Reed Switch, SMD, SPST-NO, 200V, 1A, 15-20AT

The MK23-35-C-2 is a highly reliable miniature surface-mount reed switch, perfect for applications where space is at a premium and dependable performance is critical. Featuring gull-wing SMD leads, this switch is designed for efficient pick-and-place manufacturing, ensuring a strong mechanical connection to printed circuit boards. The compact, bare glass construction offers a more economical and space-saving solution compared to over-moulded reed sensors, without compromising on functionality or longevity.

Engineered for a long life expectancy, this SPST-NO (Single Pole, Single Throw, Normally Open) switch provides exceptional electrical characteristics. It boasts an impressively low maximum contact resistance of just 150mΩ at 0.5V/10mA, minimising power loss and heat generation. Its high insulation resistance of 10¹⁰Ω at 100V ensures reliable isolation, while a minimum breakdown voltage of 0.22kVDC provides robust protection against voltage spikes.

A key feature is its precise magnetic sensitivity, with an operate point between 15 and 20 AT (Ampere-Turns), allowing for consistent and predictable switching behaviour in the presence of a magnetic field. With a maximum switching capacity of 200V and 1A (20W), it is capable of handling a wide range of low-power control and sensing circuits. Its typical capacitance is a low 0.3pF at 10kHz, making it suitable for high-frequency applications.
