KEMET SPST Through Hole Reed Switch 300 mA 110 V AC/DC Contact Resistance 150mΩ OHD3-50B

KEMET OHD3-50B SPST Through Hole Reed Switch 300 mA 110 V AC/DC is a robust switching device designed for precise electrical control within a variety of industrial and commercial applications. This reed switch provides reliable on/off operations with high-speed response and long operational life, thanks to its innovative OHD Thermal Guard series technology.

The OHD Thermal Guard includes a magnet combined with Thermorite®, a temperature-sensitive soft ferromagnetic substance. As temperature increases, Thermorite® transforms to a paramagnetic state at the Curie temperature, reducing magnetic flux density and enabling sophisticated temperature-based switching functions.

This reed switch features a SPST contact configuration with a maximum switching current of 300 mA and power handling capability up to 6 W. It supports voltages up to 110 V AC/DC, making it suitable for low-power circuits. The contact resistance is minimal at 150 mΩ, enhancing electrical efficiency.

Constructed with Nickel Iron Alloy contacts and equipped with tab lead terminals for through hole mounting, this switch is durable and easy to integrate into circuit boards. Its dimensions of 27 mm length, 13.5 mm width, and 12.5 mm depth provide a compact form factor for space-efficient designs.

Operating temperature ranges from -20°C up to 150°C enable use in various environmental conditions. The switch is dust, explosion, and corrosion-proof, ensuring reliability in harsh settings. It complies with UL, CSA, RoHS, and TUV standards, offering assured quality and safety compliance.
