What is non flush mounting?
Non-flush mounting is installation method used with inductive sensors (inductive sensor) whose sensing faces are not surrounded by a metal housing. In this way, the sensing field is not subject to pre-damping, allowing for larger switching distances (switching distance) than with flush mounted sensors.
What does an inductive sensor do?
An inductive sensor is a device that uses the principle of electromagnetic induction to detect or measure objects. An inductor develops a magnetic field when a current flows through it; alternatively, a current will flow through a circuit containing an inductor when the magnetic field through it changes.
What is quasi flush?
A third and newer type of sensor housing available is sometimes called “quasi-shielded” or “quasi-flush”. This term is used when referring to a sensor that has a “shielded” housing design, yet has to be mounted similar to a “non-shielded” model to achieve its full sensing range.
What is flush type sensor?
Flush-style sensors actually have a shield that restricts the magnetic field so that it only radiates out of the face of the sensor. Flush-style, or shielded sensors, can be mounted flush in a metal bracket or even in your machine without the metal causing the sensor to false trigger.
What is flush mountable?
Typically this is the easiest mounting option. Flush mount – the plate of the wired button sits or rests on the surface of the wall but the guts of the button will sit inside the wall. With these types of buttons the electrical components of the button will stick into the wall itself.
What are capacitive sensors used for?
Capacitive sensors are most often used to measure the change in position of a conductive target. But capacitive sensors can be effective in measuring presence, density, thickness, and location of non-conductors as well. Non-conductive materials like plastic have a different dielectric constant than air.
What is the difference between capacitive and inductive sensors?
Inductive sensors detect the proximity of metal targets to an inductive coil sensor, whereas capacitive sensors detect the change in capacitance between a sensor and electrode.
What is IR sensor?
An infrared sensor (IR sensor) is a radiation-sensitive optoelectronic component with a spectral sensitivity in the infrared wavelength range 780 nm … 50 µm. IR sensors are now widely used in motion detectors, which are used in building services to switch on lamps or in alarm systems to detect unwelcome guests.
What is accelerometer sensor?
An accelerometer is a device that measures the vibration, or acceleration of motion of a structure. The force caused by vibration or a change in motion (acceleration) causes the mass to “squeeze” the piezoelectric material which produces an electrical charge that is proportional to the force exerted upon it.
What is shielded proximity sensor?
Answer. As shown in Figure 1, the surface of the detection coil on Shielded Proximity Sensors is covered with metal, so the flux is concentrated at the front of Sensors, which reduces the influence of surrounding metal.
What is NPN vs PNP?
PNP sensors produce a positive output to your industrial controls input, while NPN sensors produce a negative signal during an “on” state. NPN, or “sinking” output sensors, work in the opposite way, sinking ground voltage to an input when it’s on.
