Auto-Polarization Switches
Diamond Engineering is now offering auto-polarization switches. Our AUTOPOL-40-4T-M is a programmable SP4T mechanical switch operating from DC – 40 GHz and features 2.92 mm K-connectors. The unit features both front panel and remote control options – via Serial, 5V TTL, or from control pendant with position indicator. A proprietary mechanical design cleans the contacts after each switch, which provides up to 5-million cycles at 0.01dB repeatability with an overall 10-million cycle-rated lifespan.
Educational discounts are available for students, teachers or staff of universities or technical schools.
