Description

Autonics capacitive sensor M18, NPN NC - CR18-8DN2

8 mm Sensing distance, Normally Closed, Cable type connection

Regarding Capacitive proximity sensor, when the sensor power is on, the oscillation of the current is close to 0V. When the object approaches to the sensor, the capacitance will be increased and the oscillation of the current is increased. This output section will be operated by increasing the oscillation. The CR18-8DN2 is a non-contact detector (sensor) which detects the sensing target when it comes close. The diameter of sensing face is 18mm and the sensing distance is also 8mm which makes the product able to detect objects in this active area.

As a quick report, CR18-8DN2 from Autonics comes with the following features:

  • 18 mm Sensing side diameter.
  • 8 mm Sensing distance.
  • NPN Normally Closed control output.
  • Detect various materials including metal, iron, stone, plastic, water, and grain.
  • Built-in sensitivity adjuster for convenient configuration.
  • Operation indicator (red).
  • Ideal for level detection and position control.
  • IP66 ingress protection structure according to IEC standards
  • Red LED status indicator

Body

This Autonics capacitive sensor's case and nut parts are made of Polyamide 6.

The CR18-8DN2 features IP66 ingress protection.

The red LED on its body acts as the process indicator.

Connection

The CR18-8DN2 features standard cable type connection. This black cable covers the sensor's 3 wires. It is 4 mm in diameter and 2 meters in length, and is made of PVC.

Sensing specifications

This Autonics CR Series sensor's sensing side diameter is 18 mm. The maximum distance that this sensor can detect its standard sensing target, which is a 50x50x1 mm piece of iron, is 8 mm. This so-called sensing distance differs from one sensing target to another, based on their material, size, etc.

Although almost no one talks about the setting distance of an inductive sensor, it is a big deal to know this concept. Every sensor can detect its standard sensing target in a specified range, no matter what changes occur in ambient temperature, voltage fluctuations, etc. This distance, which is called the setting distance, is from 0 to 5.6 mm for this proximity sensor.

Control output 

The output of the CR18-8DN2 is NPN Normally Closed. NPN stands for Negative-Positive-Negative transistors.

Temperature

There are limitations in temperature and humidity in which CR18-8DN2 capacitive sensor is used:

  • Storage temperature: -30 … 80°C
  • Storage humidity: 35 to 95%RH
  • Ambient temperature: -25 … 70°C
  • Ambient humidity: 35 to 95%RH

Environment resistance is rated at no freezing or condensation.
