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."

Plain bearings with 2-point support structure

A new structure supports the spindle with upper and lower plain bearings to significantly increase rigidity. Unlike ball bearings, these bearings efficiently disperse lateral loads on the spindle, significantly reducing the risk of breakage.

Metal guide whirl-stop structure

Metal guide whirl-stop structure

Spindle whirl-stop is accomplished by means of a metal guide requiring a several μm level assembly precision. Unlike a plastic guide, the risk of measurement error and glass scale breakage caused by deformation, wear, and other deterioration is significantly reduced.

3) Value on the HG-S1010 / HG-S1110.
4) Button-type probe for evaluation purposes was installed on the test sample for the lateral load resistance test.

No "value skipping" or "unset zero point"

Displacement is measured by reading a glass scale with a different slit pattern at each reading position using a high-resolution sensor. This eliminates "value skipping" even when measuring at high speed, and there is no concern of "unset zero point".

Class-top accuracy

Class-top accuracy
* As of January 2017, according to our survey.

Tip deviation amount of 35 μm 1.378 mil or less

Tip deviation, which impairs measurement accuracy, is minimized. The precision with which the HG-S series is assembled makes this possible.
* Less than 40 μm 1.574 mil on the HG-S1032.

Resistant to upward thrust impact
Spindle stopper installed at the lower section

Even if unexpected upward thrust occurs, the lower part of the spindle blocks the impact. Damage to the internal structure, including the glass scale, is minimized.

* As of January 2017, according to our survey.

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.

Hot-swappable

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)

Versatile and Easy-to-Use Controller Dual display for added indication flexibility (equipped with NAVI function) Equipped with intuitive circle meter Anytime selection of function to copy

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).

Easy-to-understand 2-line digital display

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.

Equipped with intuitive circle meter

Anytime selection of function to copy

The selective copy function significantly reduces the man-hours required for initial setting and maintenance.

Anytime selection of function to copy

Easy tolerance setting
Simple 1-point teaching

Align with master workpiece and press ENTER key for easy tolerance setting.

Easy tolerance setting

No need for trigger input
Equipped with self-trigger hold function

No need for trigger input

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.

Lateral connection of slave units for added operational ease
Connection of up to 15 slaves units

One master unit can be connected with up to 15 slave units in any order. This allows easy multi-point calculations.

Controller variations
?Master unit (1 model)?
?High performance type (analog current + input / output)
?Slave unit (3 models)?
?High performance type (analog current + input / output)
?Standard type (input / output)
?Wire-saving type

Lateral connection of slave units for added operational ease
* End plates (optional) must be mounted on both sides of the controller after the connection of slave units.
