NI4-M12-AZ31X AC 2-Wire Proximity Sensor Introduction
The NI4-M12-AZ31X is a non-contact inductive proximity sensor designed for AC two-wire operation, providing reliable object detection in industrial automation systems. Featuring a non-flush installation design with M12 threaded housing, this sensor offers practical detection distance while maintaining mechanical durability. The brass-nickel plated body combined with PBT sensing face ensures reliable performance in typical workshop environments.
This normally open sensor operates within 20-250V AC range, delivering stable switching characteristics through built-in protection circuitry. When metallic targets enter the effective sensing range, the output contact changes state within milliseconds, meeting general industrial response requirements. The cylindrical housing allows flexible mounting orientation, and compact dimensions facilitate integration into space-constrained applications.
Ideal for position verification on production lines, conveyor systems, and automated machinery, the sensor demonstrates consistent performance in detecting ferrous metal components. The IP67-rated sensing face provides basic protection against dust and moisture ingress. Pre-calibrated sensitivity settings ensure out-of-the-box functionality for common metal detection tasks.
Technical highlights:
- Operating frequency: 25Hz standard
- Sensing distance: 2mm ±10% (iron)
- Ambient temperature: -25℃ to +70℃
- Housing material: Nickel-plated brass
- Connection: 2m PVC cable with M12 plug
Installation tips:
- Maintain recommended clearance from metal backgrounds
- Avoid direct exposure to high-pressure water jets
- Verify electrical load compatibility before connection
- Allow sufficient warm-up time in low-temperature conditions
This product provides cost-effective solution for basic proximity detection requirements, balancing performance and durability for general industrial applications.
