KEMET SPST Through Hole Reed Switch 300 mA 110 V ac/dc OHD1-80B

KEMET OHD1-80B SPST Through Hole Reed Switch is engineered for efficient on/off switching in electronic circuits, rated for 300 mA current and 110 V ac/dc voltage. It supports applications requiring compact, reliable switching components with through-hole mounting.

The reed switch features a nickel iron alloy contact material that ensures durability and low contact resistance of 150 milliohms, suitable for signals from extremely low power levels up to 6 W. Its SPST configuration delivers single pole single throw operation, ideal for switching control circuits.

Designed with wire terminals, the switch provides secure connections and stable mechanical mounting. The dimensions of 5.5 mm width, 18 mm length, and 5.6 mm depth make it compact for use in various industrial and electronic assemblies.

This product is part of the OHD Thermal Guard series, incorporating a unique temperature-sensing ferromagnetic material (Thermorite®) that adjusts its magnetic flux density according to temperature, enabling thermal protection functionality. Its robust construction offers excellent environmental durability, long operational life, and high-speed response.

Typical industrial uses include temperature detection and overheating monitoring in devices such as power transistors, power modules, room heaters, amplifiers, motors, hard drives (HDDs), floppy disk drives (FDDs), and other general appliances requiring precise switching control under thermal stress.

The switch features a SPST contact configuration for single-pole, single-throw applications. Maximum switching current is 300 mA, supporting low power operations up to 6 W. Contact resistance is low at 150 milliohms ensuring efficient conductivity.

Constructed with nickel iron alloy contacts for long operational life and durability. Terminals are wire type with through-hole mounting for stable installation. Operating temperature range spans from minus 20°C to 150°C, suitable for diverse environments.

Compact dimensions measure 5.5 mm width, 18 mm length, and 5.6 mm depth. Compliance with TUV, UL, RoHS, and CSA standards assures high quality and safety. Manufactured in Japan, the OHD Thermal Guard series offers high reliability with thermal sensing magnet technology.
