Contact-Type Digital Displacement Sensor HG-S

Slim & Robust Sensor Unit
Introducing Contact-Type Digital Displacement Sensor
Featuring optical absolute method in the slim and strong unit body

CE Marking

CE Approved

NEW Sensor head 32 mm 1.260 in type has been added since March, 2017.


Lateral loads often occur in the workplace, so we conduct our own unique lateral load resistance testing. There is a reason why you can use this product with peace of mind for a long time.

Withstands more than 100 million sliding operations under application of lateral load (Typical value) *1

*1Value on the HG-S1010 / HG-S1110.
*2Button-type probe for evaluation purposes was installed on the test sample for the lateral load resistance test.

Shock resistance 200 G approx.

1,960 m/s2 acceleration in X, Y and Z
directions three times each

Vibration 20 G approx. resistance:

10 to 500 Hz frequency (HG-S1032: 10 to 150 Hz frequency), 3 mm 0.118 in double amplitude (Maximum acceleration 196 m/s2) in X, Y and Z
directions for two hours each

Vibration / shock resistance No. 1* in class

Durability to withstand more than 200 million vertical sliding operations (typical value)*1

*1Value on the HG-S1010 / HG-S1110.

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

High-precision sensor head [HG-S1110(R)]
* As of January 2017, according to our survey.

Bending-resistant cable

A bending-resistant cable provides peace of mind even when the sensor is installed on a movable tool.


The sensor head can be replaced without turning OFF the instrument power.

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.

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.

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.
