Any material with a dielectric other than air can be detected. Proximity switches can detect conductive and non-conductive materials, including metal, iron, stone, plastic, water, and grain. A built-in sensitivity adjuster makes it easy to configure the detection distance, making it ideal for use in a variety of environmental settings. CR series proximity switches are available in DC 3-wire type and AC 2-wire type.

Autonics product catalog includes photoelectric switches, fiber optic sensors, area sensors, rotary encoders, proximity sensors, pressure sensors, timers, counters, temperature controllers, panel displays. The brand's photoelectric sensors are designed to detect the presence, presence or distance of an object using a light emitter and receiver. These sensors feature NPN, PNP, or relay circuitry and operate over a temperature range of -25 to 65 degrees Fahrenheit. Autonics also offers two-phase and five-phase stepper motors that convert electrical energy into rotational energy

proximity switch(English:proximity sensor) also calledproximity sensor, which is a device that can detect the presence of nearby objects without contactsensor.

Proximity sensors typically emitelectromagnetic fieldorElectromagnetic radiationbundle (e.g.infrared) and observeelectric fieldOr the change of the return signal to realize the function. The object that can be detected is called the target of the proximity switch. Different types of proximity switches have different goals, such asCapacitive Proximity SwitchorPhotoelectric switchpossible detectionplastictarget, andInductive proximityswitchCan only detect metal targets.

Sensors have a "nominal range" defined by their design, the maximum distance they can detect. Some sensors have the ability to adjust within the nominal range and to report the detection distance classification.

Therefore, the proximity switch has no mechanical parts, and there is no physical contact between the sensor and the object being sensed, resulting in high reliability and long service life.

Smartphones or similar mobile devices are often equipped with proximity switches. The device can wake up from sleep mode when a target is present within the nominal range. If the proximity sensor's target persists, the device can also ignore it and go back to sleep. A common design is that when using a smartphone to make a call, the proximity switch will detect the presence of the target and treat it as if it is placed in the ear, at which point the touchscreen will be temporarily turned off to avoid accidental operation.^[1]Proximity sensors are also used for vibration monitoring of some mechanical devices.

Proximity switches tuned to ultra-short distances can also be used as atact switch.
