  • The History of the Rotary Solenoid
    it turns can be controlled. When the solenoid is activated, the core is once again pulled into the center and the disk rotates. A spring pushes it back to its starting position as soon as power is removed. As power is generally not provided continuously, this means most rotary solenoid switches
  • How to Choose Between a Relay, Solenoid, and Contactor
    Relays, solenoids, and contactors are all switches-whether electro-mechanical or solid state-but there are critical differences that make each suitable for different applications. In this article, we will explain how each of these devices work and discuss some key selection considerations.
  • Traditional solenoid valves are simple to install but may not be the right solution for long term reliability or high flow applications
    Replacing a solenoid valve with a DynaMatic electric ball valve...Why and how?. Solenoid valves are typically easy to install and are used in applications utilizing pressure, flow, temperature and level switches. They can also be controlled by PLC units that only output a single control signal
  • Troubleshooting Reed Switches Used In Valve Position Indication
    A common method to provide remote position indication in solenoid operated valves (SOV) is to use non-contact reed switches in conjunction with a permanent magnet. This article describes some common issues experienced with non-contact reed switches when used in these systems, and how to diagnose
  • The Top 5 Trends In Medical Device Manufacturing In 2019 And Beyond
    to help you maximize productivity and profit through innovative solutions is essential to maintaining an edge over your competitors. As outlined above, the team at Johnson Electric offers an extensive range of circuits, solenoids, switches, and customized platforms designed to help proposed medical
  • Operational Cost Saving Opportunities for System Designers in Control Power
    Control panels most often have transformers feeding into Switched Mode Power Supplies (SMPS) that provide 24VDC power to PLCs, I/O cards, Solenoids, relay coils, etc. The excess heat generated in the panel and the overall operating cost provides system designers with challenges when selecting
  • Protecting Against Surges: Circuitry for DIN Valve Connectors
    an incredibly vital role: supplying power (and sometimes signal transmission) to end devices such as solenoid valves, transducers, cylinders, and pressure switches. The primary benefit for a DIN valve connector over a traditional hard-wired device is quick installation and ease of maintenance.
  • Relays: Principle of Operation for Engineers
    High current switching technology. Ledex-BLP-200 In the drive towards smart metering and control for domestic power supplies, the solenoid-operated power contactor is a key enabling technology. Utility companies and equipment manufacturers are increasingly looking for added value in this type
