  • Impacts of Shock and Vibration on a Limit Switch
    Industrial limit switches are very popular in sensing and control applications. Limit. switches are used to detect presence or absence in areas where physical contact. is allowed. Upon sensing an object, the switch actuator operates and the normally. open or closed electrical contacts inside
  • Specifications
    for a minimum of 0.002 to 0.003-in. overtravel of the basic switch to ensure adequate contact pressures and some mechanical stability. For most applications it is sufficient to ensure that the actuator force exceeds the upper limit of the operating force range of the switch. This is the force
  • Switches and the NEC
    system Wall switches and circuit breakers are likely the part of the building electrical system with which technical personnel have the most direct contact. The NEC article that covers switch connections is Article 404. The most basic prescription of 404 is that switches make or break the hot lead
  • MICRO: Spotlight
    when planarization is reached, preventing overpolishing. (S.F., South Hall, Booth 417) The HPS Integrated LoPro (ILP) two-stage valve from is a vacuum poppet valve and a bypass valve in a single unit. The valve's compact size and ultracompact limit-switch option assure that it will fit into tight
  • Traditional solenoid valves are simple to install but may not be the right solution for long term reliability or high flow applications
    applications to provide vastly improved flow characteristics and consistent performance. Electric actuators consist of a motor, a gear train, cams and limit switches. The electric actuator requires two electrical input signals; one to open and another to close the valve. DynaQuip actuators are available
