  • How to Use Relays to Control Linear Actuators
    In this post we will be going over how to use relay boards to control the motion of linear actuators. We have 2-channel, 4-channel and 8-channel relay boards available and each one does the same thing, the only difference being how many channels are usable. We will be combining the relay boards
  • Operating Principles for Inductive Proximity Sensors
    Inductive proximity sensors are used for non-contact detection of metallic objects. Their operating principle is based on a coil and oscillator that creates an electromagnetic field in the close surroundings of the sensing surface. The presence of a metallic object (actuator) in the operating area
  • Measurement and Control Basics, Fourth Edition
    , microwave, and. radar. The chapter on temperature measurement has been improved by. adding new illustrations and a section on radiation pyrometers. Coverage. of analytical measurement and control in Chapter 8 was increased by the. addition of a section on the principles of electromagnetic radiation and its
  • A Push Towards Efficiency
    are designed for demanding applications, handling up to 600 volts and 55 amps enough power for a 30-hp DC motor or a 55-hp three-phase AC motor. Optionally, the cordsets can be shielded by connecting a braided shield directly to the coupling nut. This protects against electromagnetic and radio frequency
  • Transportation Industry In A "Buzz" Over Haptics
    for driver sensory awareness and incorporation into aftermarket add-on safety solutions. Vibrotactile Haptic technologies. There are three principal types of vibration-inducing technologies: 1. Eccentric Rotating Mass (ERC). 2. Piezoelectric Actuators. 3. Linear Resonant Actuator (LRA). ERC's are motors
  • Relays: Principle of Operation for Engineers
    causes an electromagnetic repulsion (the Lorenz force). The higher the current, the greater the repulsive force. Under extreme overloads such as short circuit conditions, there is a risk that the contacts will be forced apart, and the resultant sparking and local heating could destroy the switch
  • The History of the Rotary Solenoid
    to rotary motion. When power is applied, it rotates a ratcheting mechanism using an electromagnetic coil. When the solenoid is activated, the core is pulled into the center and the disk rotates. A spring pushes it back to its starting position. The distance the ratcheting mechanism moves and the amount
  • The 5 Best Industry Applications For Linear And Rotary Solenoids
    , which is then translated into linear or rotary motion. When the ferromagnetic actuator, or "plunger," slides "IN" and "OUT," this robotic motion is harnessed to either continuously hold a position or to operate as an ON-OFF pulse (latching). Through Johnson Electric's innovative engineering and design
