Basic Information

Detects water...reliably!

UL,CE,UKCA Approved

UL : Recognition(Excluding 5 m cable length type)

Features

Strong penetrating power

As the penetrating power is strong, its beam can pass through not only translucent containers (PFA tanks, etc.) but also opaque containers of shampoo bottles, etc., and the sensor can reliably detect the liquid inside.

Strong penetrating power

- The graph above is merely a guideline. Penetrating power changes due to container material, thickness and color. We strongly recommend conducting verification tests prior to use.

Not affected by drops, bubbles or froth

It is possible to set its sensitivity adjuster so that water drops, bubbles in the water, or froth on the water surface are not detected.

Not affected by drops, bubbles or froth

Adjacent sensor mounting possible

Several sensors can be mounted adjacently by fitting optional slit masks.
Further, they can detect the liquid level accurately.

Plug-in connector type is available

Plug-in connector type which enables connection / disconnection of the cable by one-touch is available. Anyone can easily replace the sensor in a minute.

Output operation selectable

Light-ON or Dark-ON operation can be selected.
The output operation can be changed easily.

IP67 protection

The sensor can be hosed down because of its IP67 construction and the non-corrosive stainless steel sensor mounting bracket.

Note: Take care that if it is exposed to water splashes during operation, it will detect the splashed water itself.

Applications

Detecting level of aqueous solution in resin tank

Detecting level of aqueous solution in resin tank

It can reliably detect liquid even in an opaque container.

Detecting the boundary between water and oil

Detecting the boundary between water and oil

Since it does not detect oil, it can reliably detect the boundary between water and oil.

Detecting presence of liquid in colored bottle

Detecting presence of liquid in colored bottle

Aqueous liquids in translucent colored bottles can be reliably detected.

NOTE: Mounting bracket is not supplied with the sensor. Please select from the range of optional sensor mounting brackets (five types).

Notes:

1)The sensing range shortens depending on the thickness, material, color, etc., of the container or pipe.

2)Models whose model name on the product nameplate is followed by “P” are emitters, while those whose model name is followed by “D” are receivers.

5 m 16.404 ft cable length type and plug-in connector type

5 m 16.404 ft cable length type (standard: 2 m 6.562 ft) and plug-in connector type (standard: cable type) are also available.
(5 m 16.404 ft cable length type is not available for the EZ-11-PN.)
When ordering this type, suffix "-C5" for 5 m 16.404 ft cable length type, "-J" for plug-in connector type to the model No.
Please order the suitable mating cable separately for plug-in connector type.
(e.g.) Plug-in connector type of EZ-11-PN is "EZ-11-PN-J ".

Cautions For Use

  • Never use this product as a sensing device for personnel protection.
  • In case of using sensing devices for personnel protection, use products which meet laws and standards, such as OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country.

Mounting

  • The tightening torque should be 0.5 N·m or less.

Wiring

  • When connecting the mating cable to the plug-in connector type sensor, the tightening torque should be 0.4 N·m or less.

Stability indicator

  • The stability indicator (green) lights up when the incident light intensity has sufficient margin with respect to the operation level. If the incident light intensity level is such that the stability indicator lights up, stable sensing can be done without the light received operation and the light interrupted operation being affected by a change in ambient temperature or supply voltage.

Others

  • Because these units use special emitter and receiver elements, they are susceptible to the effects of operating ambient temperature and humidity. Sensitivity adjustment should be performed in the environment in which they will actually be used.
  • Do not use during the initial transient time (100 ms) after the power supply is switched on.
