Unit volume ratio reduced by about 50%^*

* As compared to EX-10 series

The world's thinnest^* sensor dimension of 3 mm 0.118 in has been achieved by utilizing 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.
* Among photoelectric sensors with built-in amplifier, as of April 2017 in-company survey

Capable of sensing an extremely small ø0.3 mm ø0.012 in object without slit [EX-Z11□]
A slit is provided on the front side of the main sensor body. The sensor can detect a ø0.3 mm ø0.012 in object (the smallest-object sensing capability in the industry*) without using an optional slit.
* Among photoelectric sensors with built-in amplifier, as of April 2017 in-company survey

Capability to sense a small ø1.0 mm ø0.039 in 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 ø1.0 mm ø0.039 in object from a long distance of 500 mm 19.685 in. Since the spotlight is clearly visible, the sensing position can be easily confirmed.

ENVIRONMENTAL RESISTANCE

Bending-resistant cable type available for all models
Bending-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 diameter as previous models, but the outside diameter of the cable is 2.0 mm 0.079 in and thinner than the cables of the EX‑10 series. This facilitates cable routing.

Waterproof IP67
The sensors features an IP67 rating 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.

Options

A variety of mounting brackets are available!
A spacer for mounting at the back (1 type) for through-wall sensing and sensor mounting brackets (3 types) are available to meet a diversity of sensor installation needs.
