Small magnetic switch ・ Sensor High precision Origin Positioning φ3
HS-320 High Precision 0.05μ Non-contact Precision Positioning Magnetic Sensor Makome Research Institute
Non-contact magnetic switch/sensor boasting a repeat accuracy of ±0.05μm and a protective structure of "IP67".
This is a magnetic switch designed to detect the center of the origin position of precision moving tables with high accuracy. It outputs a switching signal at the center of the magnetizing body for detection, achieving a high repeatability accuracy of ±0.05 micrometers. Due to its magnetic detection method, it is unaffected by dirt and dust, and it fully complies with the protective structure "IP67," providing excellent environmental resistance such as waterproofing and dustproofing. The 'HS-320' and 'HS-321' models are widely used for thermal expansion compensation in ultra-precision machining equipment. 【Main Features】 - The detection head is compact at Φ3mm×17mm, allowing for flexible installation positions. - Connected by a 500mm long cable from the detection head to the detector. - The 'HS-320' has an output format of NPN transistor open collector output (normally open). - The 'HS-321' has an output format of PNP transistor open collector output (normally open). *For more details, please contact us.
