Protech SDI-77XL2-EX-IND Motion Sensor

Protect critical industrial sites with the Protech SDI-77XL2-EX Motion Sensor, engineered for reliable security and surveillance in hazardous locations. This stereo Doppler motion sensor is built to be mounted in an explosion-proof enclosure, enabling safe monitoring where flammable gases, vapors or combustible dusts are present. Dual receiving channels and proprietary circuitry minimize false alarms caused by vibration or periodic movement, while 10-position digital switches let you fine-tune detection area and required motion to suit complex environments. With wired DC power, user-selectable Form C relay output and up to 100' maximum sensing distance, the SDI-77XL2-EX integrates seamlessly into industrial alarm and monitoring systems. Tamper protection and a lock-in alarm on component or power failure ensure continuous alerting and faster incident response. Ideal for refineries, chemical plants, grain handling and other high-risk facilities, this Protech PIR motion sensor alternative delivers dependable motion detection where safety and regulatory compliance matter.
