German reckmann gmbh sensors, reckmann gmbh models, reckmann gmbh prices

reckmann gmbh sensors, also known as displacement sensors, are a type of sensor used to detect the distance to an object to perform a preset function, and are widely used. Main products include mobile phone proximity sensors and long-distance measurement sensors, applied in smart belts. Proximity sensors can be classified into optical proximity sensors, infrared proximity sensors, ultrasonic proximity sensors, etc., based on their working principles. Most proximity sensors used in mobile phones are infrared proximity sensors, which have an infrared emitting tube and an infrared receiving tube. When the infrared light emitted by the transmitting tube is received by the receiving tube, it indicates that the distance is close, and the screen needs to be turned off to prevent accidental operation. When the receiving tube does not receive the infrared light emitted by the transmitting tube, it indicates that the distance is far, and there is no need to turn off the screen. The working principles of other types of proximity sensors are similar; they also determine the distance by emitting and receiving some kind of substance, such as ultrasonic waves or light pulses.

reckmann gmbh sensor principle

Optical measurement and control systems vary depending on the principle of how luminous flux acts on photoelectric elements. Based on the nature of the output from the photoelectric elements (optical measurement and control systems), they can be divided into two categories: analog photoelectric sensors and pulse (switching) photoelectric sensors. Analog photoelectric sensors convert the measured quantity into a continuously changing photocurrent, maintaining a single-valued relationship with the measured quantity. Analog photoelectric sensors can be classified into three major types based on the method of measuring the target object: transmission (absorption) type, diffuse reflection type, and shading (beam blocking) type. The transmission type refers to placing the measured object in the optical path, where light energy from a constant light source passes through the object, is partially absorbed, and the transmitted light projects onto the photoelectric element. The diffuse reflection type refers to light from a constant source projecting onto the measured object, reflecting off its surface, and then projecting onto the photoelectric element. The shading type refers to when part of the luminous flux from the light source is blocked by the measured object, changing the luminous flux projected onto the photoelectric element; the degree of change depends on the position of the measured object in the optical path.

reckmann gmbh sensor features

1) Long detection distance: If a detection distance of 10m or more is maintained in through-beam configurations, it enables long-distance detection that other methods (magnetic, ultrasonic, etc.) cannot achieve. 2) Few restrictions on detected objects: Since the detection principle relies on shading and reflection caused by the object, unlike proximity sensors that limit detection to metals, it can detect almost all objects such as glass, plastic, wood, and liquids. 3) Short response time: Light itself is high-speed, and the sensor circuits consist of electronic components, so there is no mechanical operating time, resulting in very short response times. 4) High resolution: Advanced design techniques allow the projected light beam to be focused into a small spot, or special light-receiving optical systems can be constructed to achieve high resolution. This allows for the detection of tiny objects and high-precision position detection. 5) Non-contact detection possible: Detection can be performed without mechanical contact with the object, preventing damage to both the object and the sensor. Therefore, the sensor can be used for a long time. 6) Color discrimination possible: The reflectance and absorptance of light formed by the detected object vary depending on the wavelength of the projected light and the color combination of the object. Using this property, the color of the detected object can be determined. 7) Easy adjustment: In types that project visible light, the beam is visible to the eye, facilitating adjustment of the detected object's position.

reckmann gmbh sensor applications

Photoelectric sensors using photoelectric elements as sensitive components are diverse and widely used. Based on the nature of the output, they can be divided into two categories: (1) Photoelectric measuring instruments that convert the measured quantity into a continuously changing photocurrent can be used to measure physical quantities such as light intensity, object temperature, light transmittance, displacement, and surface condition. Examples include illuminance meters for measuring light intensity, photoelectric pyrometers, photoelectric colorimeters and turbidimeters, photoelectric alarms for fire prevention, and automatic inspection devices and instruments for checking the diameter, length, ellipticity, and surface roughness of machined parts, all of which use photoelectric elements as sensitive components. Semiconductor photoelectric elements are not only widely used in civil industrial fields but also hold an important position in military applications. For example, lead sulfide photoresistors can be used to make infrared night vision devices, infrared cameras, and infrared navigation systems; (2) Devices that convert the measured quantity into a continuously changing photocurrent. Various photoelectric automatic devices are made using the characteristic of photoelectric elements outputting "on" or "off" electrical signals when exposed to light or no light. Photoelectric elements serve as switching photoelectric conversion components. Examples include photoelectric input devices for computers, switching temperature control devices, and digital photoelectric tachometers for speed measurement.
