Advanced infrared technology: The E3Z-R61 uses an infrared photoelectric sensor with a reflective structure, where the transmitter and receiver are co-located and detect reflected light from a reflector. Detection is triggered when an object interrupts the beam. Versatile output and high compatibility: This model provides NPN output, switchable between normally open and normally closed states, suitable for various circuit designs. It operates within a DC 6–36 V voltage range and supports up to 300 mA current. Adjustable sensing range and robust design: The sensor offers an adjustable detection range of 0 to 2 m (approximately 6.5 ft), customizable for different application requirements. It operates reliably in temperatures from –25 °C to +75 °C and features an ABS housing for strong interference resistance and high stability, suitable for indoor and outdoor use. Multi-purpose applications: Suitable for security systems, industrial automation, and residential convenience applications, including garage doors, automatic doors, overhead door safety systems, small-object detection on production lines, storefront entrance detection, and parking assistance or alarm systems. High-performance sensing: The E3Z-R61 is engineered for reliable, consistent detection across diverse industrial, commercial, and residential applications. Color: Black Material: ABS Package Contents: 1 × E3Z-R61 sensor with mounting bracket Note: Actual product color may vary slightly due to lighting conditions and screen settings. Measurement tolerance: ±1–3 cm.
