Protech SDI-77XL2-ABC XL2 Series Piramid Dual Technology Sensor, Wide Angle, Includes Lens A, B, and Lens

Secure outdoor perimeters with a sensor engineered to reduce false alarms and deliver reliable intrusion detection. The Protech SDI-77XL2-ABC XL2 Series PIR motion sensor combines Stereo Doppler microwave and Passive Infrared technologies so both sensors must trigger to create an alarm—improving detection accuracy for security, surveillance, and remote monitoring applications. The unit ships with interchangeable Lenses A, B and C to customize wide-angle coverage for fences, parking areas or loading bays. Designed for challenging environments, the sensor operates from 10–28V DC and performs across -40°F to 150°F, ensuring continuous operation in extreme climates. Low current consumption (150 mA at 12V with LEDs off) and a compact wall-mount housing simplify integration into existing alarm panels and perimeter systems. Choose the Protech SDI-77XL2-ABC for dependable, false-alarm-resistant outdoor detection that protects assets and reduces nuisance alerts.
