Contactors typically utilize explosion proof gasket or hermetically sealed enclosures. Many current ratings are available in conventional, plug-in or bus bar mounting. Custom designs are commonplace. Vacuum and gas filled enclosures ensure long service life and high performance for specialized switching applications. Typical product benefits include small size and weight, low leakage current, fast operate times, high resistance to shock, vibration and temperature extremes, functionality in RF applications, and bounceless operation in many applications.
Protective relays provide sensing and control functions for engine generators and switchgear.
Solenoids are applied when a defined mechanical motion is required. Most high performance solenoids are designed for a specific application. Typical applications include a number of aerospace applications. Voltage, frequency, and phase sensors perform power line monitoring functions. Solid state relays employ semiconductor chips in lieu of moving contacts, and are used as substitutes for electromechanical relays in high reliability and specialized applications.
