S4A104-B-UNIS4A104-B-UNI Unidirectional 24.125Ghz Automatic Door Microwave Sensor
The S4A104-B-UNI is a high-precision unidirectional microwave sensor engineered specifically for automatic door activation systems. Utilizing 24.125GHz Doppler microwave technology housed in a compact IP54 ABS plastic enclosure, it detects approaching traffic while ignoring departing motion, drastically reducing unnecessary door hold-open times and conserving energy. Featuring flexible multi-directional angle adjustments (0°–60° vertical, +15° to -15° horizontal) and universal 12-24V AC/DC power compatibility, it provides highly efficient, reliable door activation for commercial entrances.
