Non-contact sensors monitor or measure an object’s physical characteristics without coming into contact with the target directly. They are employed in the measurement of physical attributes including thickness, closeness, displacement, or distance.
Contrarily, non-contact sensors work without requiring direct physical contact with the system or object being monitored. This can be seen, for instance, in the use of infrared thermometers by doctors to take a patient’s temperature.
Touch temperature sensors employ conduction to track temperature changes and rely on direct physical contact with an object. Non-contact sensors, on the other hand, do not need to make physical contact in order to detect temperature changes because they use an optical analysis of infrared radiation.
The Global Non-Contact Sensor market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
New non-contact precision CMM sensor from Hexagon is available. The Manufacturing Intelligence division of Hexagon has developed a new high-speed, non-contact sensor for coordinate measurement machines (CMMs) to meet the growing demand from the consumer electronics and medical sectors to quickly inspect delicate parts with a range of surface finishes, including those produced using additive manufacturing, without applying damaging pressure.
Because traditional tactile inspection can be time-consuming and parts are frequently damaged during measurement, manufacturers of components with susceptible surface finishes struggle to operate at maximum efficiency.
When every component needs to be examined, the distortion of delicate surfaces reduces production and, ultimately, the bottom line.
With the new HP-OW chromatic white light sensor, contract manufacturers may use cutting-edge technologies and materials while OEMs benefit from greater measurement speed and flexibility.
It is simple to measure parts made of sensitive materials fast and accurately, including electronics parts like LED vehicle lights and solar panels, thanks to the sensor’s capacity to measure components with transparent, glossy, rough, and matte finishes.
Non-contact capabilities also provide high-throughput inspection of medical equipment, including surgical implants, where each component needs to be checked thoroughly.
According to the business, additive manufacturing technologies present particular difficulties since parts frequently need to be measured throughout production to verify quality, yet the cycle time to perform precision inspection of rough, unfinished parts can be too long.
The inspection of a variety of parts made of various materials is sped up by the capability to automatically switch between tactile and non-contact sensors in response to variations in application.
By automating inspection from beginning to end with a sensor-changing rack, the overall process efficiency can be increased for a part like a windscreen where numerous distinct measuring techniques are required for the inspection.
