CHERRY’s magnetic proximity sensors, speed sensors, and rotary position sensors are designed to meet the unique needs of OEM customers.
Speed – Proximity – Rotary Sensors – Cherry
The sensor is operated by rotating a magnetic actuator close to the face of the sensor. Output voltage varies with angular position of the magnet relative to the sensor. Optimal performance is achieved with Cherry’s AS500106 magnetic actuator.
Rotary Position Sensors
This sensor is designed for continuous output corresponding to the rotation angle of a magnetic actuator, typically CHERRY’s AS500106. Two electrically independent outputs assure very high reliability.
Features and Benefits
Angular position sensor with high tolerance for misalignment, Dual (redundant) outputs assure very high reliability, Non-contact sensing up to full 360° rotation, No mechanical interface, Nothing to break or wear out.
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.”
“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.”
