The proximity switch is a switch with mechanical moving parts that do not directly contact, and can operate on the position. When an object is close to the surface of the sensor switch for a certain distance, it does not require mechanical contact or any pressure to make the switch act, thereby driving DC power or giving it to the computer. (PLC) The device provides control instructions. Proximity switch is a kind of switch sensor (namely non-contact switch), it has the characteristics of travel switch, but also has the performance of the sensor, stable and reliable performance, fast frequency response, long service life, strong anti-interference ability, etc., and has Waterproof, anti-corrosion and anti-vibration features. The proximity switch is the inductive switch referred to in ordinary life. It is a very advanced switch. This switch does not require mechanical transmission of power. It is a very safe switch. There are many types of switches, including inductive switches. , Capacitive type, Hall type, AC and DC type.
The gtek proximity switch is a kind of switch that has no direct contact with mechanical moving parts and can operate on the position. When an object is close to the surface of the sensor switch for a certain distance, it does not require mechanical contact or any pressure to make the switch act, thereby driving a direct current Or provide control instructions to a computer (PLC) device. Proximity switch is a kind of switch sensor (namely non-contact switch), it has the characteristics of travel switch, but also has the performance of the sensor, stable and reliable performance, fast frequency response, long service life, strong anti-interference ability, etc., and has Waterproof, anti-corrosion and anti-vibration features.
gtek photoelectric switch principle After the modulated pulse generated by the oscillation circuit passes through the reflection circuit, the light pulse is radiated from the luminous tube GL. When the measured object enters the range of the light receiver, the reflected light pulse enters the photosensitive transistor DU. And in the receiving circuit, the optical pulse is demodulated into an electrical pulse signal, and then amplified by an amplifier and synchronized gating and shaping, and then the interference is eliminated by digital integration or RC integration, and finally after a delay (or no delay), the driver is triggered to output the photoelectric Switch control signal. Photoelectric switches generally have good hysteresis characteristics, so even if the detected object shakes in a small range, it will not affect the output state of the driver, so that it can be kept in a stable working area. At the same time, the self-diagnostic system can also display the light receiving status and stable working area to monitor the work of the photoelectric switch at any time.
