1. Introduction
This manual provides essential information for the proper installation, operation, and maintenance of the TURCK NI3-EG08K-AP6X-V1131 Proximity Sensor. This inductive sensor is designed for non-contact detection of metallic objects.
Please read this manual thoroughly before using the product to ensure safe and efficient operation.
2. Safety Information
WARNING: Failure to follow these safety instructions may result in personal injury or equipment damage.
- Ensure power is disconnected before installation, wiring, or maintenance.
- Only qualified personnel should install and service this device.
- Do not exceed the specified voltage and current ratings.
- Protect the sensor from mechanical impact and excessive vibration.
- Do not modify the sensor. Unauthorized modifications may void the warranty and compromise safety.
3. Product Overview
The TURCK NI3-EG08K-AP6X-V1131 is an inductive proximity sensor with the following key features:
- Model: NI3-EG08K-AP6X-V1131
- Sensing Range: 3mm
- Housing: M8x1 Barrel, 8mm stainless steel full threading short barrel
- Output Type: Normally Open (NO) PNP
- Operating Voltage: 10-30 VDC
- Connection: M8 Male Connector (Picofast 3-Pin QD Connector)
- Indicator: 1 LED for operational status
This sensor is designed for reliable detection of metallic targets in industrial environments.
4. Setup and Installation
4.1 Mounting
- Select a mounting location where the sensor is protected from physical damage and excessive heat.
- Mount the M8x1 barrel sensor using appropriate mounting hardware, ensuring it is securely fastened.
- Maintain adequate clearance around the sensor head to prevent interference from surrounding metallic objects, especially for flush-mountable sensors. Refer to the sensor's datasheet for specific mounting distances.
4.2 Wiring
The sensor features a 3-pin M8 male connector. Follow the standard wiring color code for PNP sensors:
- Pin 1 (Brown): +VDC (10-30VDC)
- Pin 3 (Blue): 0VDC (Ground)
- Pin 4 (Black): Output (PNP, Normally Open)
Connect the sensor to the control system according to the wiring diagram provided by the system manufacturer. Ensure all connections are secure and properly insulated.
5. Operation
Once properly installed and wired, apply power to the sensor. The integrated LED indicator will provide status feedback:
- LED ON: Indicates that a metallic object is within the sensing range and the output is active (PNP output is high).
- LED OFF: Indicates no metallic object is detected within the sensing range and the output is inactive (PNP output is low).
The sensor operates by generating an electromagnetic field. When a metallic object enters this field, it causes a change in oscillation, triggering the output. The 3mm sensing range ensures reliable detection for small to medium-sized metallic targets.
6. Maintenance
The TURCK NI3-EG08K-AP6X-V1131 sensor is designed for minimal maintenance. However, regular inspection can prolong its lifespan and ensure reliable operation.
- Cleaning: Periodically clean the sensor face to remove dust, dirt, or debris that may accumulate and affect sensing performance. Use a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Inspection: Check wiring and connections for any signs of damage, corrosion, or loose contacts. Ensure the sensor is securely mounted and not subjected to excessive vibration.
- Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges.
