Available in a variety of sizes

proximity switch

Available in Ø 8 mm, Ø 12 mm, Ø 18 mm, Ø 30 mm size models, allowing installation in tight or limited spaces as well as a variety of other user settings.

Long sensing distance

Compared to PR series standard inductive sensors, PRD series sensors have a longer sensing distance (1.5 to 2 times).

Strain Relief Cable

The PRD series utilizes a strain relief cable with improved flexural strength of the cable connection components for greater durability when flexing the cable.

Except PRDT08-□DO-□ model

Oil Resistant (PVC) Cable

Robust oil-resistant cables allow the sensor to be installed in environments with hydraulic or cutting fluids.

IP67 protective structure

IP67 protective construction provides trouble-free operation even in wet or dusty environments

Application

Application example of automation system

Here are examples of elevators, escalators and parking systems using Autonics products.
Manufacturing of electrical components

Inductive proximity sensors are used to detect the presence of carriers on conveyor belts during the manufacture of electrical components.
Beverage Container Packaging Conveyor

Proximity sensors are used to detect and count the number of bottles during beverage packaging.
Parking Tower Entrance/Exit

Inductive proximity sensors are mounted on the parking turntable to detect the plates on the turntable and control the set/fixed position of the turntable.
automatic drilling machine

Proximity sensors are used as limit switches to check the exact position of parts in automatic drilling machines.
shoe glue press

Proximity sensors are used to detect pallets in shoe line rubber presses.

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.
