HF Series MEDER electronic High Frequency and High Power Reed Relays DESCRIPTION High voltage RF Reed Relays use a patented coil encapsulation, external electrostatic shields, and magnetic shields. For this series we use a special copper-plated Form A switch with a breakdown voltage up to 10 kVDC. The contacts are suitable for carrying current up to 3 Amps (5 Amps available) at 30MHz. FEATURES APPLICATIONS * Normally open contacts (Normally closed contacts are available) * 5 Amps available * Radio frequency technology * Antenna tuning units * Transmit / receive requirements DIMENSIONS All dimensions in mm [inch] ORDER INFORMATION Series Nominal Voltage Contact Form Switch Model Pin Out HF XX - XX 54 - X Options 05, 12, 24 A, B 5, 6, 7, 8, 9 www.meder.com 160 Part Number Example HF05 - 1A54 - 6 05 is the nominal voltage 1A is the contact form 54 is the switch model 6 is the breakdown voltage (6 kVDC) MEDER electronic HF Series High Frequency and High Power Reed Relays COIL DATA Contact Form Switch Model All Data at 20 C 1A 54 1B ** Coil Voltage Coil Resistance Pull-in Voltage Drop-out Volage Nominal Coil Power VDC VDC VDC mW Max.
