OKI Sensor - Reed Switches and Sensors

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."

Hasco Components - Reed and Electromechanical Relays

Hasco Components has been in the business of Relays, Reed Switches and Reed Relays since 1976.



Hasco Components - Reed and Electromechanical Relays



Product line encompass 500 different types of relays and electromechanical relays, as well as 24 types of reed relays, that range from milliamps to 80 amps. They include both DC and AC coil voltages and can also switch from one pole to 4 pole



RPR Series RPR SeriesSPDT 10 Amp





10A switching capability, Subminiature, standard PCB layout, Plastic sealed and flux proofed types available.



611 Series Mini Reed Relays 0.5 Amp







Encapsulated Body, Small size, PCB Mounting, Available with external shield.



delabs Notes



Reed relays can be used even for switching High Frequency and Low Level Signal. The control circuit should not induce cross talk. It is good for even making precision Attenuators.
