Motor-driven Coax Phase Shifters
Available from Advanced Technical Materials (ATM) Inc
ATM's motor driven phase shifters utilize DC motors with integrated, long life gear reductions ideal for High Reliability applications. The unit will operate with a set DC voltage between 18-30VDC, commonly found in most systems or by a separate DC power supply. Motor speed will vary based on Voltage used. Maximum running current is 250mA & 600mA max starting.
To prevent motor damage, Micro switches are used to stop the motor at the minimum and maximum travel positions
Units are provided with a 9 pin D Sub Male connector allowing for control voltage, end point indication if desired, and follower potentiometer.
See connector pin-out details.
These devices are best controlled by an external Double-Pole/Double-Throw (DPDT) switch or the optional ATM External control module.
Any one of ATM's Phase Shifters can be mounted to a motor drive.
