RF Contactors


Kintronic Labs manufactures a complete line of single pole, double throw or double pole, double throw RF contactors ranging in current rating from 40A to 200A and in voltage rating from 20kV to 80kV. The RF contactors with current rating between 40A and 100A utilize solenoid drive requiring a short duration 110VAC or 220VAC pulse. Solenoids are available such that AC voltage can be field changed between 110 and 220 VAC. The RF contactors rated for 100A or higher utilize a DC linear actuator that requires a separate drive circuit to convert AC to DC drive.

Kintronic’s Radio Frequency Contactors are the result of years of experience in the manufacture and installation of special RF energy transfer devices and are especially designed for high voltage radio frequency switching. They are also ideally suited to DC voltage switching in high voltage rectifier circuits.

The contactors require no holding power and are designed to operate with a momentary application of control voltage. Each RF Contactor includes four microswitches for interlock and position status purposes. Contactors are available with a current rating ranging from 40 Amps to 200 Amps and a voltage rating between 20 and 55 KV (HIGHER) as shown in the table if you click on the “ONLINE REQUEST FOR QUOTE SYSTEM” button in the upper right hand corner.

Kintronic’s RF Contactors are utilized in Medium Wave/AM directional antenna systems for pattern and transmitter switching and also in wall mountable stand alone enclosures for application as Main/Auxiliary/Dummy Load Transmitter switches. Manually operated switches or electrically operated with a manual backup mode are available on special request. Kintronic Labs maintains a large inventory of replacement parts for all the RF contactor models.
