Advanced infrared technology: The E3Z-R61 uses an advanced infrared-controlled photoelectric switch. It adopts a reflective structure, where the transmitter and receiver are co-located and the beam is reflected back through a reflector. Any object blocking the beam will trigger the sensor. Versatile output and high compatibility: This model provides NPN output, which can be switched between normally open and normally closed states, suitable for a variety of circuit designs. It works effectively in the voltage range of DC6-36V and supports currents up to 300mA. Adjustable sensing range and durable design: The sensor provides a flexible detection range of 0 to 6.5 feet, which can be adjusted according to different operational needs. It can withstand temperatures from -25℃ to +75℃ and adopts ABS housing, strong anti-interference and high stability, suitable for indoor and outdoor applications. Multi-purpose applications: It is suitable for a wide range of uses such as security systems, industrial automation and residential convenience facilities. It can be effectively applied to garage doors, automatic doors, overhead door security systems, small object detection on production lines, storefront entrance detection, and parking assist or alarm sensors. High-Performance Sensing Solutions: The E3Z-R61 sensor is designed to provide reliable detection for a variety of applications. The sensor is ideal for automation and safety in industrial environments.
