Proximity sensors are widely used in many industries, including industrial automation, automotive applications, mobile devices, robotics, and much more. The UM18-218127111 is an inductive proximity sensor. It uses inductive technology and is used to detect the presence of metal objects without contact. This type of sensor detects objects made from ferromagnetic materials, such as iron, steel, and nickel. It is also capable of detecting non-metallic objects, such as paper, plastics, and wood.

The UM18-218127111 has a 110mm tubular housing that can accommodate a range of detection objects from 5mm to 15mm. This tubular brass housing provides a robust and corrosion-resistant detection area. The sensor comes in a variety of voltage ratings, including 12 - 24V DC. It is also available with PNP (positive-negative-positive) or NPN (negative-positive-negative) outputs. The sensor operates at a frequency of 2.4 kHz, and has a maximum switching current of 200mA. It is capable of detecting objects at a distance of up to 18mm and has an operating temperature range of -25°C to 70°C.

The principle of operation for the UM18-218127111 is based on the electromagnetic induction (EMI). The sensor is composed of three main components, which are the primary winding coil (PWC), the secondary electromagnetic coil (SEC) and the signal amplifier board (SAB). When a metal object is positioned in front of the sensor, the PWC generates a Magnetic field. This magnetic field is received by the SEC, which in turn induces a current in it.

The induced current is then amplified and sent to the SAB, which magnifies the signal and passes it to the output. If the output signal exceeds a certain threshold, the output is activated and the sensor is said to be \'ON\' or \'detected\'. If the signal falls below the threshold, the output is de-activated and the sensor is \'off\'.

The UM18-218127111 inductive proximity sensor can be used in a wide range of applications, such as in industrial automation systems, security systems, and in robotics. It is a highly reliable and accurate proximity sensor that is suitable for use in environments where high accuracy and reliability are essential. Furthermore, this sensor is capable of detecting objects through non-metallic materials, making it a versatile and cost-effective solution for detecting metals, plastics, wood, and other materials.
