The slim unit body contains plain bearings with 2-point support structure disperses load and achieves superb durability. The sensor head offers long life and reduces maintenance costs dramatically.
Superb craftsmanship!
The accuracy and robustness of the HG-S series are backed by master craftsmanship.
The plain bearings are accurately aligned with the center of the spindle during their installation to the top and bottom sections of the body to ensure smooth sliding.
This process involves careful adjustment of each bearing by a skilled worker. Even though the plain bearing has a certain width, the clearance is managed to the accuracy of several μm.
Those with experience in mechanisms design will know that this value signifies amazingly high control precision.
The high-precision, robust sensor is made possible by master craftsmanship.
Maximize the high accuracy of our sensors in your pursuit of "ever higher levels of quality."
Resistance to lateral load
Withstands more than 100 million sliding operations under application of lateral load (reference value)
Optical absolute method eliminates "value skipping." (equipped with highresolution CMOS)
The high-resolution CMOS sensors read the glass scales that have different slit patterns at different read positions to measure the amount of movement. This provides accurate measurements without "value skipping" even in highspeed measuring operations. It also eliminates "unset zero point."
Class-top accuracy

Resistant to upward thrust impact
Spindle stopper installed at the lower section
Even when a sudden upward thrust impact occurs, the resulting load is applied only to the lower section of the sensor unit. This structure minimizes adverse effect of impact on the glass scales.

Hot-swappable
Change of sensor head without turning off the power supply
The sensor head can be changed safely without turning off the controller. This reduces the man-hours required for the change of line setup for processing of different workpieces, thus achieving a significant reduction of setup change time.
Versatile and Easy-to-Use Controller
The controller features the industry's first* dual display and offers versatile
functions and excellent ease of use.
It allows simple and reliable operation of the advanced measurement function in a diversity of applications.
* As a sensor product using optical absolute method, as of September 2015 (according to our company's investigation)
High-speed response of 3 ms in combination with any sensor head
Provided with maintenance mode useful on production floor
The following data are stored and can be used for analysis on the spot.
• Abnormal sensor head upward thrust value
• Number of sensor head upward thrusts
• Cumulative total number of sliding operations
Alarm setting for notification of upward thrust
Alarm can be set to notify an upward thrust (stroke) that exceeds the set level. This allows you to conduct a preventive maintenance before the sensor head generates a malfunction.
Easy-to-understand 2-line digital display
The 2-line digital display simultaneously shows sensor head measurement and judgment value.
The 2-line digital display simultaneously shows head measurement (measured value) and judgment value (calculated value).
Equipped with intuitive circle meter
Values between allowable maximum and minimum values are indicated in green. Values outside of the allowable range are indicated in orange. This provides at-a-glance understanding of the margin to the tolerance limits.
Anytime selection of function to copy
The selective copy function significantly reduces the man-hours required for initial setting and maintenance.
Easy tolerance setting
Simple 1-point teaching
Align with master workpiece and press ENTER key for easy tolerance setting.
No need for trigger input
Equipped with self-trigger hold function

Easy setting of time length from measurement start to measurement stabilization.
Minimizes measurement fluctuation due to the vibration caused by stopping of spindle rotation.
(1)Static width setting
Stability range above the ST level can be set as desired.
Set the range where measurements are considered to be stable.
(2)Delay timer setting
Desired delay time after measurement exceeding the ST level can be set.
Set the time required for stabilization of measurement.
