High-Performance C-Frame solenoid. Jewell Instruments delivers proven levels of performance and high reliability with its new MAGNETEC family of open-frame solenoids. Their coil systems are terminated with .025 inch square pins to accommodate commercially available mating terminals and connectors. The use of terminals inserted in a coil bobbin flange is far more cost effective than electrically terminating an open-frame solenoid with long leads. The materials used in the coil system are capable of withstanding a total temperature of 130°C (ambient plus heat rise)!
