This sensor finds the exact spot of metal items. It does this without touching them. It uses induction to sense how far away a target is. Then it sends a steady signal. You can choose a 0-10V voltage or a 4-20mA current output for your system.
Features and Benefits
- Inductive sensing: It finds metal objects without touching. This means no moving parts to wear out.
- Analog output options: Pick 0-10V voltage for simple setups. Or use 4-20mA current for a better signal over long runs.
- Linear position data: The signal changes directly with the target's distance. This gives you exact, live position data for small changes.
- Standard M12, M18, and M30 sizes: These common threaded bodies let you mount the sensor easily. It fits into existing fixtures or machines.
Applications
- Factory automation: Use this sensor to watch how far machine slides, robot arms, or actuator shafts move.
- Making things and checking them: Check metal sheet thickness. Measure how much a part wobbles on a lathe. Confirm part placement during assembly.
- Process control: Use this sensor to follow the position of control valves or gates. This gives you feedback for closed-loop systems.
What It Is
This is an M18 linear displacement capacitive sensor, designed for industrial use as a proximity sensor. It provides an analog output signal, selectable between 0-10V voltage or 4-20mA current. As a capacitive sensor, it detects the presence of objects by sensing changes in an electrical field, making it suitable for a range of non-contact detection tasks. Unlike optical sensors, capacitive proximity sensors can detect both metallic and non-metallic materials.
Key Uses & Applications
This capacitive sensor is ideal for applications requiring precise linear displacement measurement or proximity detection. Its M18 barrel sensor design allows for straightforward integration into various industrial setups. Common uses include level sensing of liquids or granular materials, position sensing for machinery, and detecting objects on conveyor belts. The analog voltage or current output provides continuous data, enabling fine control and monitoring in automation systems.
How to Choose
When selecting a capacitive sensor, consider the required output signal, either 0-10V voltage or 4-20mA current, to ensure compatibility with your control system. The M18 diameter is a key specification for mounting. For testing a proximity sensor, you would typically apply the correct power supply and then introduce a target object within its detection range, observing the change in the output signal. For optimal performance, ensure the sensor is mounted securely and protected from excessive vibration or extreme temperatures.

Sensor Type: Inductive Proximity Sensor. Theory: Current Sensor. Q: What kind of output signals can I get from this sensor, and what's its accuracy? A: This analog sensor provides a continuous signal that changes with the target's distance. You can order it with either a 0-10V voltage output or a 4-20mA current output, depending on your PLC or controller's needs. The linearity error is kept under 1%, giving you a consistent and repeatable measurement.. Q: How well does the sensor's body hold up against dust and liquids? A: The housing is made from nickel-plated brass, which protects it against corrosion in typical industrial environments. It has an IP67 rating, so it's fully sealed against dust ingress and can withstand being submerged in water up to one meter deep.. Q: Can this sensor detect non-metallic materials like plastic or wood? A: This is an inductive sensor, which means it's specifically for detecting the presence and distance of metal objects. For sensing non-metallic targets or liquid levels through a container wall, you would need to use a capacitive sensor instead.. Q: What happens if the sensor I receive is faulty or stops working? A: It comes with a 12-month warranty that covers any defects in materials or how it was made. If you have any problems with it during that time, just contact our support team and we'll help you with a replacement or troubleshooting.. Q: How does the detection range change between the M12, M18, and M30 models? A: The sensing distance is directly tied to the diameter of the sensor head. The M12 model provides a 0-4mm linear range, the M18 gives you 0-8mm, and the largest M30 version has a 0-15mm range. You'd pick the size based on the specific travel distance you need to measure..
