German Moduloc sensor Moduloc model Moduloc price

Moduloc sensors are measurement feedback devices that operate based on the optical principle of gratings. Grating scales are frequently used in the closed-loop servo systems of CNC machine tools and can be used to detect linear or angular displacement. The measurement output signal is a digital pulse, characterized by a large detection range, high detection accuracy, and fast response speed. For example, in CNC machine tools, they are often used to detect the coordinates of tools and workpieces to observe and track tool path errors, thereby compensating for tool motion errors. Depending on the manufacturing method and optical principle, grating scales are divided into transmissive gratings and reflective gratings.

Moduloc sensor principle

Optical measurement and control systems are diverse, developed based on different principles of how luminous flux acts on photoelectric elements. According to the nature of the output from the photoelectric element (optical measurement and control system), they can be divided into two categories: analog photoelectric sensors and pulse (switching) photoelectric sensors. Analog photoelectric sensors convert the measured variable into a continuously changing photocurrent, exhibiting a single-valued relationship with the measured variable. Based on the method of measuring the target object, analog photoelectric sensors can be classified into three major types: transmission (absorption) type, diffuse reflection type, and light-blocking (beam interruption) type. The transmission type refers to a configuration where the measured object is placed in the optical path; the light energy emitted by a constant light source passes through the measured object, and after partial absorption, the transmitted light is projected onto the photoelectric element. The diffuse reflection type refers to a configuration where light from a constant source is projected onto the measured object, and after reflecting off the surface of the measured object, it is projected onto the photoelectric element. The light-blocking type refers to a configuration where the luminous flux emitted by the light source is partially blocked by the measured object, causing a change in the luminous flux projected onto the photoelectric element; the degree of change depends on the position of the measured object within the optical path.

Moduloc sensor features

1) Long detection distance: If a detection distance of 10m or more is maintained in a through-beam configuration, 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 light blocking and reflection caused by the object, unlike proximity sensors that limit detection to metals, it can detect almost any object, including glass, plastic, wood, and liquids. 3) Short response time: Light itself is high-speed, and the sensor circuit consists entirely of electronic components, so there is no mechanical operating time, resulting in a very short response time. 4) High resolution: Advanced design techniques allow the emitted light beam to be focused into a small spot, or a special receiving optical system can be constructed to achieve high resolution. This allows for the detection of tiny objects and high-precision position detection. 5) Non-contact detection: 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: The reflectivity and absorptivity of light formed by the detected object vary depending on the wavelength of the emitted light and the color of the object. Utilizing this property, the color of the detected object can be determined. 7) Easy adjustment: In types that emit visible light, the beam is visible to the eye, facilitating adjustment of the detected object's position.

Moduloc 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, used to measure physical quantities such as light intensity, object temperature, light transmission capability, displacement, and surface condition. Examples include lux 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, ovality, 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 to output "on" or "off" electrical signals when exposed to light or in darkness. 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.
