MADER switch Germany MADER model MADER price

MADER switch is a switch that measures the operating speed of the measured object and converts it into an output signal. Speed measurement switches include linear speed measurement switches and rotational speed measurement switches. With the development of technology, traditional measuring equipment can no longer meet current needs and has gradually been eliminated, while laser speed measurement switches have been widely used. They are of great significance in the product production process. By connecting to a computer, they can perform automated and intelligent measurement control on the measured object. This is the product of the combination of modern measurement technology and computer technology.

MADER switch principle

Optical measurement and control systems manufactured based on different principles of luminous flux acting on photoelectric elements are diverse. According to the nature of the output quantity of the photoelectric element (optical measurement and control system), they can be divided into two categories: analog photoelectric switches and pulse (switching) photoelectric switches. Analog photoelectric switches convert the measured quantity into a continuously changing photocurrent, which has a single-value relationship with the measured quantity. Analog photoelectric switches can be divided into three major categories based on the method of measuring the target object: transmission (absorption) type, diffuse reflection type, and light-blocking (beam obstruction) type. The so-called transmission type refers to placing the measured object in the optical path; the light energy emitted by the constant light source passes through the measured object, and after being partially absorbed, the transmitted light is projected onto the photoelectric element. The so-called diffuse reflection type refers to the light emitted by the constant light source being projected onto the measured object, and then reflected from the surface of the measured object onto the photoelectric element. The so-called light-blocking type refers to when the luminous flux emitted by the light source is partially blocked by the measured object, causing the luminous flux projected onto the photoelectric element to change; the degree of change is related to the position of the measured object in the optical path.

MADER switch features

1) Long detection distance: If a detection distance of more than 10m is maintained in the through-beam type, it can achieve long-distance detection that other detection methods (magnetic, ultrasonic, etc.) cannot. 2) Few restrictions on detected objects: Since the detection principle is based on light blocking and reflection caused by the detected object, unlike proximity switches that limit detected objects 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 switch circuits are composed of electronic components, so there is no mechanical operating time, resulting in a very short response time. 4) High resolution: Advanced design technology can concentrate the emitted light beam into a small spot, or a special receiving optical system can be constructed to achieve high resolution. It can also perform detection of tiny objects and high-precision position detection. 5) Non-contact detection is achievable: Detection can be performed without mechanical contact with the detected object, so there will be no damage to the detected object and the switch. Therefore, the switch can be used for a long time. 6) Color discrimination is achievable: The reflectance and absorptance of light formed by the detected object vary depending on the wavelength of the emitted light and the color combination of the detected object. Utilizing this property, the color of the detected object can be detected. 7) Easy to adjust: In types that emit visible light, the emitted light beam is visible to the eye, making it easy to adjust the position of the detected object.

MADER switch applications

Photoelectric switches using photoelectric elements as sensitive components are diverse and widely used. According to the nature of the output quantity of the photoelectric switch, they can be divided into two categories: (1) Photoelectric measuring instruments that convert the measured quantity into a continuously changing photocurrent, which can be used to measure physical quantities such as light intensity, object temperature, light transmission capability, displacement, and surface condition. For example: 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 processed parts, all of which use photoelectric elements as sensitive components. Semiconductor photoelectric elements are not only widely used in the civil industrial field but also hold an important position in military applications. For example, lead sulfide photoresistors can be made into infrared night vision devices, infrared cameras, and infrared navigation systems; (2) Converting the measured quantity into a continuously changing photocurrent. Various photoelectric automatic devices are made using the characteristic of photoelectric elements to output "yes" or "no" electrical signals when exposed to light or no light. Photoelectric elements are used as switching photoelectric conversion elements. For example, photoelectric input devices for electronic computers, switching temperature regulation devices, and digital photoelectric tachometers for speed measurement.
