Proximity Sensors

A Proximity Sensor is a device specifically designed to detect the presence of objects or targets without touching them. They use various technologies such as inductive, capacitive, magnetic, and optical. A Proximity Sensor requires an entity to be physically close for its sensing element to trigger a response. The response can either be sent as an electrical or optical signal, and is used for an automated controller or other device to initiate or complete a certain action. Proximity Sensors are commonly used in industries such as automotive, factory automation, security, HVAC, and healthcare applications.

UM18-211161101 Application Field and Working Principle

The UM18-211161101 is a 2-wire Inductive Proximity Sensor. This device is a self-contained sensor used to detect the presence of metallic objects. It operates using conduction power from an AC or DC power source, and transmits a signal out to an external control device to indicate the presence of an object. The UM18 sensor is typically used in applications such as sensing when a machine part is in the proper alignment in a manufacturing environment, or as a vehicle safety system that triggers an alarm when an object is too close to the sensor.

The working principle of the UM18-211161101 involves sending out a low-voltage alternating magnetic field. When a metallic object is close enough to the sensing range of the sensor, a response is sent out to the control device. The frequency of the alternating magnetic field decreases when there is an object present. This decrease will be picked up by the control system, triggering an action.

The UM18 has a sensing range up to 8mm and a working voltage of 12-24V DC. It features a protective coating on the outside to prevent against dust and moisture, and a robust 8-pole plastic molded housing, with a built-in connector for easy installation. This device also includes tuning thresholds that allow users to adjust the ideal sensing level for their specific application.

The UM18-211161101 is well suited for a variety of industries such as automotive, factory automation, security, HVAC, and healthcare application. It is suitable for applications such as monitoring the alignment of machines, detecting objects close to the sensor, and sending an alarm when something is too close to the sensors.
