HF Series Reed Relay
The HF Series is a high-frequency, high-power reed relay designed for RF and telecommunications applications requiring reliable switching and elevated current handling. Capable of carrying up to 5 A at 30 MHz, the HF Series combines robust performance with precision signal control. Its specially packaged coil features a PCB pin-out for the coil only, while the switch contacts are configured for direct wiring (sky wiring), allowing flexible integration into RF systems.
Equipped with patented external electrostatic and magnetic shielding, the HF Series supports SPST-NO (Form A), SPST-NC (Form B), and DPST-NO (Form 2A) contact configurations. It is rated for up to 25 W, 500 VDC, and 1.5 A, with coil voltage options of 5 VDC, 12 VDC, and 24 VDC. With breakdown voltage up to 9,000 VDC, the HF Series is ideal for antenna switching, radio transmitters, and high-frequency telecom equipment.
