Description
The MK20/1-B-100W Reed Sensor is a high-performance, magnetically operated proximity switch housed in a compact, cylindrical module. Designed for versatility and ease of integration, this sensor is ideal for applications requiring reliable position sensing without physical contact. The module features an interconnect cable for simple wiring and is designed to be mounted on a fixed surface, with the actuating magnet placed on the moving component (such as a door or window).
This SPST-NO (Single-Pole, Single-Throw, Normally Open) switch is built to withstand varied environments with an operating temperature range of -20°C to 70°C. Whether you are implementing security contact systems, liquid level detection using magnetic floats, or precision position sensing, the MK20 series provides a durable and responsive solution for your automation and monitoring projects.
