KEMET SPST Through Hole Reed Switch 300 mA 110 V AC/DC OHD3-40B

KEMET OHD3-40B SPST Through Hole Reed Switch is designed for reliable electrical switching in industrial and commercial environments. Rated for 300 mA maximum switching current and 110 V AC/DC voltage, it offers excellent performance and durability. The switch features nickel iron alloy contacts ensuring low contact resistance of 150 mΩ, contributing to low power loss and long service life.

Its compact dimensions of 27 mm length, 13.5 mm width, and 12.5 mm depth enable easy installation in varied equipment. The through hole mount with tab leads allows secure placement on circuit boards. This reed switch operates over a wide temperature range from -20°C to +150°C, making it suitable for harsh operating conditions.

The OHD Thermal Guard series incorporates a unique design with Thermorite®, a temperature-sensitive soft ferromagnetic material, providing high reliability for on/off operations and thermal problem countermeasures. Its magnetic flux density decreases as temperature increases, enhancing thermal safety and control.

It delivers a high-speed response and supports switching signals with power levels from extremely low (0.1 mW or lower) up to 6 W. This versatility allows integration into various applications such as atmospheric temperature detection, overheating monitoring of power transistors, power modules, room heaters, motors, hard disk drives (HDDs), floppy disk drives (FDDs), and other general appliances.

Designed for superior environmental durability, the reed switch is dust, explosion, and corrosion-proof, suitable for industrial, laboratory, HVAC, manufacturing, and commercial uses. RoHS compliance ensures it meets environmental safety standards.
