STANDEXMEDER MK23 Series Reed Switch SPST-NO 15-20AT SMD

The STANDEXMEDER MK23-66-C-2 is a high-quality, miniature SPST-NO (Single Pole, Single Throw, Normally Open) reed switch in a surface-mount (SMD) format. Designed for reliability and compactness, this bare glass version offers an economic and space-saving alternative to over-moulded reed sensors, making it ideal for modern, densely populated printed circuit board (PCB) designs.

This switch is engineered for a broad spectrum of sensing and switching applications. It features a robust glass length of 14mm and a diameter of 2.2mm, housing the reliable magnetic reed contact mechanism. With a maximum switching voltage of 200VDC and a switching current of 0.5A DC, it is rated for a switching power of 10W, ensuring dependable performance in low-power control circuits.

A key advantage of this reed switch is its close differential and long life expectancy, providing stable and repeatable switching action. It is built to operate reliably across a wide temperature range from -40°C to +130°C, making it suitable for use in demanding environments. The maximum contact resistance is a low 0.15ohm, minimising power loss and signal degradation.

Typical Applications

This versatile component is perfect for ON/OFF control, proximity detection, motion sensing, and position detection in general-purpose electronic systems. Its specific applications span numerous critical industries, including:

• Air conditioning system controls
• Gas metering equipment
• Barcode scanners
• Security panels and alarm systems
• Water flow gauges and meters

Its reliability also makes it a preferred choice for commercial, aerospace, defence, military, automotive, security, test measurement, sensing instrumentation, and general industrial applications. The STANDEXMEDER MK23 Series represents a trusted solution for designers requiring a compact, long-life magnetic switch.
