Frequently Asked Questions
Q: What type of doors is the CNB-204E infrared detector sensor compatible with?
A: The CNB-204E reflective infrared detector sensor is designed for automatic door control systems, including sliding doors, swing doors, and access-controlled commercial entrances. Its wide power range (AC/DC 12–36V) and adjustable detection angle make it compatible with a variety of auto-door setups.
Q: How do I adjust the detection area of this infrared sensor?
A: The detection area can be adjusted by changing the detector angle between 0 and 10 degrees using the built-in DIP switch. Sensitivity fine-tuning is also available to tailor the sensor's response to your specific installation environment.
Q: What do the LED indicator lights mean on the CNB-204E sensor?
A: The sensor features two LED status indicators: a green light means the unit is in standby mode and operating normally, while a red light activates when the sensor receives a signal from a detected moving object, indicating the relay output has been triggered.
Q: Can this infrared detector be used outdoors?
A: Yes. The CNB-204E is rated for operating temperatures from -20°C to 60°C (-4°F to 140°F), making it suitable for both indoor and outdoor automatic door control installations within this temperature range. Check your specific environment to ensure it falls within these operating conditions.
