A new fiber amplifier unit able to detect the “presence or absence” of workpieces with “solid stability” at an “amazing price” is now available.

Low price is achieved by eliminating extra elements and by using new technologies.
Since fiber sensors are used in large quantities, E3X-ZV makes a huge contribution to reducing your equipment cost.

Equipped with sufficient functions and performance to detect presence or absence,
E3X-ZV can be used as-is in your equipment.

Fiber sensors are used in large quantities in parts feeders, roll presses for secondary batteries, assembly machines for digital products, and so on to detect the presence or absence of workpieces. However, many customers are using fiber amplifier units with excessive functions and performance that may make them accordingly costly.
OMRON narrowed down functions and performance to those required to detect presence or absence, and optimized the materials used as well as the production process in addition to making full use of new technologies to achieve an amazing price. The more you use the more cost savings you gain, making E3X-ZV a fiber amplifier unit with the best cost performance.

Material cost is reduced by mounting the 7-segment display and operation panel on one substrate.
Furthermore, “membrane switches” are used for operation buttons to achieve both cost reduction and improved click feeling.

The L/D (Light on / Dark on) button present on conventional models is eliminated, reflecting customer opinion that the button is rarely used and is a cause of malfunction by accidental pressing.
This helped not only to reduce material cost, but also to enlarge the display and increase visibility.

Adopting the mutual interference prevention by light emission cycle change eliminated the optical communications function between amplifiers required in previous methods, and reduced the material cost.
Furthermore, this method allows the activation of the mutual interference prevention function without needing the fiber amplifier units to be installed in close contact with each other.

The 2-channel model equipped with amplifier functions for two fiber amplifier units enables substantial purchase cost reduction since the required number of units is halved. Furthermore, it greatly contributes to the downsizing of equipment and control panel in addition to allowing substantial reduction in wiring workload and power consumption.

E3X-ZV is equipped with functions and performance for reliable use in a wide range of equipment.

With a detection performance equivalent to that of E3X-HD and a minimum detectable object of 3 μm, E3X-ZV has sufficient margin to detect small parts and the size of metallic parts of electronic components used to determine their front or rear.

With high dynamic range (seven times that of E3X-HD), E3X-ZV stably detects from black to glossy objects.
Light saturation is avoided, even when the background is a glossy surface, by sufficiently lowering the light intensity.

E3X-ZV is equipped with ON/OFF-delay and one-shot timer to enable output control even in an environment without PLC.

With a response time of 50 μs, equivalent to that of E3X-HD, E3X-ZV captures seams on fast moving sheets without fail.
Given a 10-mm wide electrode, it can theoretically detect seams also on sheets moving at 200 m/s.

The mutual interference prevention function based on different frequencies prevents mutual interference among up to four channels.
Wiring the fiber units and cables is also easy since the fiber amplifier units need not be installed in close contact with each other.

Adjustment of light intensity and threshold level to their optimal value is possible by just pressing the button twice. The operation is common regardless of the workpiece or installation conditions, allowing for a unified setting method that eliminates variations owing to operators.

When installing in large quantities, both the necessary installation space and wiring workload increase. However, using the 2-channel model allows you to not only save space, but also substantially reduce the power consumption and wiring workload.

Decrease in incident level due to LED deterioration or dirty fiber unit is detected to compensate and bring it to the level at the time of tuning to save you the trouble of re-tuning. It is particularly useful when working with through-beam or retro-reflective models.

Since buttons are indicated with +, −, □, and ◯, operation can be easily transmitted over the phone, enabling remote support.

Saving the factory default settings or settings at the time of site start-up using the user save function saves all information including the tuning information. If during operation, a fiber amplifier unit needs to be restored to the saved settings as a result of an erroneous operation by a site operator, this can be done easily and on-site by instructing a user reset. Contents saved by the user save function are not cleared by the setting initialization.
