GS-7710A / 7710NA
(GS-7210 series 
)
GS-7000 series are pen-figured type of linear
gauge sensors at φ8mm, which are mostly suitable for multi-point
measurement.
It can save the space at the measurement area and its structure
is conforming to the IP67 protection class which has enough
durability against harsh environment.
Four models are available at GS-7000 series as following.
| GS-7710* / 7710A (* Discontinued) |
Standard type |
|---|---|
GS-7210L*
 |
Low
measuring force (less than 0.3N) type |
| GS-7710N* / 7710NA (* Discontinued) |
Nut-mounted type which protects the stem from the over-tighten force |
| GS-7210LN* |
Nut-mounted and low measuring force type |
High accurate measurement is possible by the
combination of the digital gauge counter, model DG-4140 or
DG-2310. It can be also possible to connect the sequencer
(PLC=Programmable Logic Controller) directly through our
converter model DG-0010/0020.
Features
8-mm diameter slim body
Designed for use in harsh environments which require protection class IP67 (GS-7710A/ 7710NA/7710* / 7710N* only)
Nut-mounted and low measuring force types are provided for your selection.
Structure Conforms to the IP67 Protection Class
It indicates the number code of protection class with respect to the penetration of obstacles, water, and oil. IP6X indicates that the enclosure is completely dust-tight, with no ingress of dust. IPX4 indicates that the enclosure is protected against drops of water and splashing water from any direction. IPX7 indicates that there are no penetration of the water even though it sinks in the water tank at a depth of 1 meter in 30 minutes. Further, IPXXG indicates that the enclosure is protected against oil drop and oil splashes from any direction. |

| *1: | Four compatible digital counters are available. The DG-4140 / 4610 / 4190 can be used at a resolution of 1 µm, and the DG-2310 at a resolution of 0.5 µm. |
| *2: | Use the linear gauge sensor in a vertical orientation, with the
measuring element pointing in the downward direction. The measuring force value is the value when there is no dust-protection rubber in place. |
