Robust and slim body contributes to a longer service life
The optical absolute method eliminates “value skipping” and “unset zero point”!

Sensor that diagnoses its own state. Featuring a self-monitoring function!

Self-monitoring function released by using the digital displacement sensor communication unit SC-HG1 in combination with digital displacement sensor HG-S series and HG-T series.

Slim & light body

Box type with an ultra-slim 11 mm 0.433 in width. Furthermore, the unit weighs only approx. 80 g. (Note 1)
Note 1: Values on the 10 mm 0.394 in type (HG-S1010□ / HG-S1110□)

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.

Bending-resistant cable

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

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.

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.

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”.

Tip deviation amount of 35 μm 1.378 mil or less (typical value) 

Value calculated from the clearance of the upper and lower plain bearings.

[40 μm 1.574 mil or less (typical value) on the HG-S1032 / HG-S1050 ^{(Note 2)}]
Tip deviation that reduces measurement precision is also minimized. Deviation of the measurement point is held to a minimum.
