PRESTONICS presents the DK-PS-001 TMR Sensor Assembly manufactured by DK Sensor, a next-generation magnetic proximity switch engineered as a high-durability upgrade to conventional reed switches. Fully optimized for professional “Design-in” engineering and seamless OEM appliance integration, this omnipolar sensor provides the exceptional impact resistance and Project Protection required for high-cycle consumer and industrial hardware.
The sensor is strategically configured with Tunnel Magnetoresistance (TMR) technology to ensure continuous, high-fidelity state tracking:
Next-Gen Reed Format Upgrade: Engineered specifically to replace mechanical reed switches, providing immense impact resistance and eliminating mechanical fatigue over an extended operating life.
Intelligent Omnipolar Operation: Detects magnetic fields smoothly regardless of polarity, ensuring highly stable and flexible mechanical alignment during high-volume production assembly.
Ultra-Low Power & High Speed: Features a microscopic current draw of just 1.5µA matched with a rapid 1000Hz response frequency, ideal for power-sensitive and fast-acting monitoring loops.
Ruggedized Extended Wire Harness: Enclosed in a compact 13mm housing equipped with a 215mm pre-fitted wire harness and premium Yeonho connector for straightforward plug-and-play installation.
Technical Specifications Summary:
