[ Easy to set up and saves space. ]

The air push type is part of the high-accuracy digital sensor GT2 Series.

A mechanism to move the sensor head is not necessary since it is possible to measure with a fi xed sensor head, saving space and reducing labor.

*1 For the 32 mm 1.26" and 50 mm 1.97" type, open a ø14 mm ø0.55" hole.

With the GT2, the spindle moves to the origin when it is not being supplied with air. Even if there is a problem or a condition arises where air is not being supplied, it is safe.

Due to the pressure free construction where air pressure is not directly applied to measurement parts, it is also safe to use with easily damaged workpieces.

The low stress type does not require a dust boot.

What is the low stress type?

The low stress type uses a low repulsion force spring to reduce the pressure on the target. When using a target that can be easily deformed or damaged, select this type.

When mounting additional units, be sure to use the end units (OP-26751). When mounting additional units, depending on the number of units to be added, confi rm the following specifi cation limitations.

<Up to 8 units (including main unit)>

• The power supply voltage is 20 to 30 VDC.

<Up to 9 to 15 units (including main unit)>

• The power supply voltage is 20 to 30 VDC.

• The maximum applicable current for each output is 20 mA.

• The maximum applicable current for each output is 10 mA (including DL-RB1A output current).

• The residual voltage at ON Is 1.5 V or less.

Calculation functions using expansion units

The GT2-70 Series* enables calculations such as the maximum and the minimum values of several detection points when several expansion units

(up to 14 units) are connected to a main unit. Outline of each calculation function is as follows:

Displays the resulting calculation of the average of the main unit and expansion unit(s).

Displays the difference obtained by subtracting the display value of the main unit from each of the expansion unit(s).

Displays the degree of twist calculated from the values of four sensor heads.

C8 Thickness

About “Calculation mode”

When “Calculation mode” is selected for “A1: Calculation mode”, the main unit outputs a calculation result, and output of the expansion unit is OFF.

(Except for a case where “C5: Difference from reference display” is selected)

NOTE - The calculation mode can be selected for the main unit to which one or more expansion units are connected.

About “Calculation dedicated mode”

When “Calculation dedicated mode” is selected for “A1: Calculation mode”, only the main unit outputs a calculation result, and the expansion unit outputs a judgment result based on each setting.

NOTE

- The calculation dedicated mode can be selected for the main unit to which two or more expansion units are connected.

- When the calculation dedicated mode is selected, “C5: Reference

Difference” cannot be selected for calculation method.

- When the calculation dedicated mode is selected, a sensor head cannot be connected to the main unit. Attach the supplied “sensor head connector seal” to the sensor head connector of the main unit.

❙

Bank function

With the Bank function, up to four patterns of HH, HIGH, LOW and LL set values, preset values can be registered in advance.

Since the registered settings (four patterns) can be easily changed, this function is useful for detection of several targets.

❙

About accuracy of the high-accuracy type

When the high-accuracy type measures a distance between two arbitrary points in the measuring range at an ambient temperature (20°C

(68°F)), the deviation from the actual value is 1 µm 0.04 Mil or less. For example, when a measurement result is 11 mm 0.43" , the actual value is in a range of 10.999 to 11.001 mm 0.4330" to 0.4331" . For several measurements, variations in the measured value are 1 µm 0.04 Mil or less.

❙

5-output function

(Except GT2-71MCN/71MCP)

This function enables differentiation of fi ve output statuses (HH,

HIGH, GO, LOW and LL). HH and LL outputs can also be used for jam detection.
