Digital Linear Gauge Baby sensor

BS-1210 (10µ resolution)

BS-1310 (1µ resolution)




Industrial products are being made smaller and smaller these days. The BS-1210/1310 linear gauge baby sensor is the best solution for measurement of such a small product. With the compact body, many sensors can be installed closely together even in a limited space.


The BS-1210/1310, designed based on our long-selling previous model the BS-102/112 series, measures dimensions, displacements and travels in high durability, stability and high accuracy.


  • Thin and small space-saved design. Easy setup and maintenance.
  • Conforms to the protection class IP66, meeting the dust- and splash-proof test requirements. (previous model:IP64)
  • It achieves 30 million times of sliding. (based on our internal durability test) (previous model: 10 million times of sliding)
  • Expanded in operating temperature range from 0 to 50℃ (previous model: 5 to 40 ℃)

Protection Class IP 66


Measuring and screening for height of small parts such as IC packages
