FAQs and Answers
How to Adjust the Sensing Distance?
Adjust the sensing distance based on the size and position of the target object in the actual application. Modify the sensor's response sensitivity and installation position to achieve the best sensing effect. Ensure no metal or other interfering objects are between the sensor and the target. Consider the impact of temperature and humidity on the sensing distance. After adjustment, conduct multiple tests to ensure stability and reliability in practical applications.
How to Ensure Electrical Connection Safety for MM12-70A-N-ZW0?
The sensor uses a 2-wire connection with a 2-meter long 2-core cable. Ensure the cable insulation is intact to prevent short circuits or leakage. Use shielded cables and ground the shielding layer to reduce electromagnetic interference. Conduct electrical tests after installation to check for secure connections and proper current flow.
What is the Protection Rating ?
The sensor has an IP67 protection rating, meaning it is dust-tight and can withstand short-term immersion in water without damage. This rating makes it suitable for harsh industrial environments, such as high humidity and dusty areas. Regularly inspect the housing for damage to maintain its protection rating.
How to Choose the Installation Location?
Select a dust-free, non-corrosive gas, and low electromagnetic interference environment. Avoid high-temperature, high-humidity, or high-vibration areas. Ensure the sensor is oriented correctly with the sensing face pointing towards the target object and within the detection range. Consider heat dissipation needs and avoid installing in enclosed or poorly ventilated spaces.
How to Perform Electrical Testing for MM12-70A-N-ZW0?
Before testing, ensure the sensor is properly installed and connected. Use a multimeter to check the cable continuity and resistance, ensuring it does not exceed 50Ω. Test the switch function by moving a magnet near the sensing face and verifying the output signal meets expectations.
How Does the Short-Circuit Protection Work for MM12-70A-N-ZW0?
The sensor has a short-circuit protection feature that automatically cuts off the output when a short circuit occurs, preventing damage. This protection complies with NAMUR standards, ensuring safety for the sensor and connected circuits. The sensor will resume normal operation once the short circuit is resolved.
How Does Temperature Drift Affect Detection Accuracy for MM12-70A-N-ZW0?
The sensor's temperature drift is ±10%, which means the sensing distance may slightly vary with temperature changes. To minimize this impact, use the sensor in a stable temperature environment. Regular calibration of the sensing distance is recommended when operating in extreme temperatures.
What Are the Shock and Vibration Resistance?
The sensor has a shock resistance of 30g and a vibration resistance of 10 to 55Hz with an amplitude of 1mm. These capabilities allow it to operate stably in high-vibration industrial environments. Minimize external vibration impacts during installation to extend its lifespan.
How Does the Wire-Break Protection Work for MM12-70A-N-ZW0?
The sensor features wire-break protection, which immediately detects and halts operation when a cable connection is interrupted. This prevents misoperations or equipment damage due to broken cables. The sensor resumes normal operation once the connection is restored.
How Does the Reverse Polarity Protection Work?
The sensor has reverse polarity protection, preventing damage even if the power supply is connected backward. This feature ensures safety during installation and maintenance. However, attention to polarity during connection is still necessary to avoid unnecessary issues.
