MK20/2 Series Reed Sensor

The MK20/2 Series is an ultraminiature cylindrical reed sensor designed for panel mounting in extremely compact applications. With a 2.7mm diameter housing, it offers precise magnetic sensing for industrial, security, and appliance environments. Its small footprint and flexible cable configurations make it ideal for position, level, and end-limit detection in space-constrained designs.

The MK20/2 Series delivers high-precision sensing in an ultracompact form factor, making it a trusted solution for OEMs and engineers designing in miniature or low-voltage environments.
