STANDEXMEDER MK23-90-C-2 Surface Mount Reed Switch, SPDT, 15-20AT
Compact STANDEXMEDER surface mount reed switch. SPDT, 500mA, 175V rating for HVAC, automotive, security & medical applications.
The STANDEXMEDER MK23-90-C-2 is a compact, surface-mount reed switch designed for reliable performance in a wide range of sensing applications. Its miniature, bare-glass construction offers an economical and space-saving alternative to traditional over-moulded reed sensors, making it ideal for modern, densely populated printed circuit boards (PCBs).
Featuring gull-wing (flat/bent) SMD leads, this switch facilitates easy automated assembly and provides a secure mechanical connection. The SPDT (Single Pole, Double Throw) contact configuration offers versatile switching capabilities, supporting a maximum contact current of 500mA and a switching voltage of up to 175V. With a long operational life expectancy, it is built for durability in demanding environments.
Key Specifications & Performance
- Electrical Ratings: Maximum switching power of 10W, with a low maximum contact resistance of 0.15Ω (150mΩ).
- Reliability: High insulation resistance of 10⁹Ω at 100V and a minimum breakdown voltage of 0.2kVDC ensure stable and safe operation.
- Sensitivity: The switch operates within a magnetic sensitivity range of 15 to 20 AT (Ampere-Turns), providing precise actuation.
- Compact Design: The switch features a glass body with a length of 14mm and a diameter of 2.54mm, contributing to its minimal footprint on the PCB.
This component is part of the reputable MK23 Series from STANDEXMEDER, a leader in reed switch technology. Its robust design and consistent performance make it a trusted choice for engineers requiring a dependable sensing solution.
