Oki Sensor Device is a specialty manufacturer of reed switches and related products developed specifically to respond to these user needs.

OKI Sensor – Reed Switches and Sensors

Products include Reed Switches, Proximity Switches, Shock Sensors.

“The reed switch was invented by Dr. W. B. Ellwood at Bell Telephone Laboratories in 1936. The first application was made during 1938 when the reed switch was used as a selector switch in coaxial carrier equipment. Later, improvements of the reed switches were made in parallel with the development of the telecommunications technology.”

OKI Sensor - Reed Switches and Sensors

“Structure and Operating Principles As shown in Figure 3.1, the reed switches comprise two ferromagnetic reeds placed with a gap in between and hermetically sealed in a glass tube. The glass tube is filled with inert gas to prevent the activation of the contacts. The surfaces of the reed contacts are plated with rhodium.”
