Advanced infrared technology: The E3Z-R61 uses an advanced infrared-controlled photoelectric switch. It features a reflective design with the transmitter and receiver located in the same unit, utilizing a reflector to bounce the signal back. Detection occurs when an object interrupts the beam. Versatile output and high compatibility: This model provides NPN output that can be switched between normally open and normally closed configurations, making it suitable for various circuit designs. It operates reliably within a DC voltage range of 6 to 36V and supports currents up to 300mA. Adjustable sensing range and durable design: The sensor offers a detection range from 0 to 6.5 feet, adjustable to meet different application requirements. It functions in temperatures ranging from -25C to +75C and features an ABS housing for strong anti-interference performance and high stability, making it suitable for both indoor and outdoor use. Wide range of applications: Ideal for use in security systems, industrial automation, and residential convenience devices. Common applications include garage doors, automatic doors, overhead door safety systems, small object detection on production lines, entrance detection for storefronts, and parking assist or alarm systems. High-performance sensing solution: The E3Z-R61 is engineered to deliver consistent and accurate detection, making it well-suited for automation and safety applications in industrial environments.
