Unit volume ratio reduced by about 50%*

The world's thinnest** sensor dimension of 3mm has been achieved by utilizing a new semiconductor packaging technology that does not use wire bonding.
The small unit size allows installation of sensors in a narrow space where only a conventional fiber sensor head could be installed before. The built-in amplifier also saves on installation space.

*   As compared to EX-10 series
** Among photoelectric sensors with built-in amplifier as of June 2015 (survey by our company)

Capable of sensing an extremely small Ø 0.3mm object without optional slit (EX-Z11□)

 A slit is already provided on the front side of the main sensor body. The sensor can detect a Ø 0.3mm object (the smallest-object sensing capability in the industry* without using an optional slit.

Capability to sense a small Ø 1.0mm object over long distance (EX-Z13□)

The high-brightness 4-element red LED provides strong light emission stably over a long period of time. In spite of the extremely small size, both front sensing and side sensing units can sense a small Ø 1.0mm object over a long distance of 500mm. Since the spotlight is clearly visible, the sensing position can be easily confirmed.

Inflection resistant cable type available for all models

Inflection resistant cable type with improved flex resistance is available for all models. Select the model suitable for your specific application.

The standard type comes with lead wires with the same wire diameter as previous models, but the outside diameter of the cable is 2.0mm and thinner than the cables of the EX-10 series. This facilitates cable routing.

IP67 protective structure

The sensors features an IP67 protective structure to allow their use in process lines where water is used or splashed.
Rust-resistant stainless steel sensor mounting brackets and screws are available.

Note: If water splashes on the sensor during sensing operation, it may sense water as an object.
