Protech SDI-77XL-MIL-D Lens D Dual Technology Sensor, 100 x 10' (30 x 3m)

Designed for demanding perimeter and critical infrastructure applications, the Protech SDI-77XL-MIL-D Lens D Dual Technology Sensor delivers dependable outdoor motion detection and intrusion monitoring where false alarms are not an option. This PIR motion sensor pairs a dual-element passive infrared detector with Protech’s proprietary Stereo Doppler microwave, using an AND-gated logic to ensure alarms occur only when both technologies detect activity—greatly reducing nuisance alerts from environmental noise or small animals. With a detection pattern of 100 x 10' (30 x 3m), an industrial operating range of -40 to 150 F, and low-voltage compatibility (10-28V DC, 150mA), the SDI-77XL-MIL-D is built to integrate seamlessly into commercial security and surveillance systems. Rugged construction, a protective metal hood, and EMI/RFI resistance mean reliable performance outdoors in harsh weather. LED indicators and self-checking circuitry speed troubleshooting and ongoing monitoring. Ideal for perimeter security, military sites, utilities, and high-value facilities—specify the Protech SDI-77XL-MIL-D for robust, low-false-alarm intrusion detection.
