Explosion-proof Type

IGY4 Series.
Intrinsic safety structure
IGY4 Series.

◆Explosion-proof symbol : Ex iaⅡ CT4, AT4
◆Possible to use it in Class 0 hazardous area.
◆Class A grounding (first class grounding) isn't necessary.

It's the displacement sensor of intrinsic safety type which can be used
at zone 0 (Class 0 hazardous area) and is also possible to use for
high accuracy level sensor.
Similar to the IGY3 series, Class A grounding (Class 1 grounding) is not required.
A minimum resolution of 1 μm is achieved in combination with a digital output controller.

This is the new product of fourth generation.
The Class A grounding (first-class grounding) is unnecessary like the
4th generation.
You can select "ExiaⅡAT4" which can be used for long stroke (max.3m)
in addition to the explosion protection symbol "ExiaⅡCT4".

[ Features ]

① Ex・・・Intrinsic safety structure based upon international standards

② Class A grounding (first class grounding) isn't necessary adopting a power transformer
  and photo coupler isolation system.

③ The probe can be used at Class 0 hazardous zone.

④ Possible to use max. stroke 2000mm(*1)

⑤ The cable between probe and separator can be extended max. 200m by using the dedicated cable.
  (*1)Possible to use max. stroke 3000mm using ExiaⅡAT4

[ Construction ]

● IGY4 series consist of a probe, a separator, a controller, a magnet (or a float), cable between
probe and separator, and 1m cable between separator and controller.
(*Plastic magnet or float can't be used by law.)

● Probe has 1.5m cable with it.In case of extending cable, it is possible to extend max.
  200m by using the dedicated cable (2 core with shield).
  Please connect extend cable with 1.5m cable of probe in terminal box.

● Probe and magnet (or float) should be installed in dangerous zone, and separator and controller
  should be installed in non dangerous zone.
