Cylindrical splash-resistant inductive proximity switch with long sensing distance (cable connector type) Model PRDAW Series | Autonics brand
Autonics brand PRDAW series inductive proximity switches are PTFE coated for high heat resistance and protection against failures caused by welding spatter. These proximity switches also feature long sensing ranges and excellent noise immunity. Cable connector type proximity switches offer simpler maintenance and wiring. These sensors are ideal for welding applications and can be used as a replacement for spatter-proof limit switches. Sensors feature NPN, PNP or relay circuits
PRDAW Series Inductive Proximity Switches
Coated with PTFE for high heat resistance and protection against failures caused by weld spatter. These proximity switches also feature long sensing distances and excellent noise immunity, using dedicated sensor ICs developed by Autonics. Cable connector type proximity switches provide easier maintenance and wiring work. These sensors are ideal for welding applications and can be used as a replacement for spatter-proof limit switches.
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

spot welding
All-metal inductive proximity switches are used to set the position of the car door during the spot welding process.
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.
