* The optical fiber is 2 m long on each side, so the sensing distance is 4,000 mm.

The following mode names and response times apply to the modes given in the Sensing distance column.

[E3X-HD] GIGA: Giga-power mode (16 ms), HS: High-speed mode (250 μs), ST: Standard mode (1 ms), and SHS: Super-high-speed mode (NPN output: 50 μs, PNP output: 55 μs)

[E3NX-FA] GIGA: Giga-power mode (16 ms), HS: High-speed mode (250 μs), ST: Standard mode (1 ms), and SHS: Super-high-speed mode (30 μs)

The values for the minimum sensing object are reference values that indicate values obtained in standard mode with the sensing distance and sensitivity set to the optimum values.

The first value is for the E3X-HD and the second value is for the E3NX-FA.

The sensing distances for Reflective Sensors are for white paper. (The sensing distances for the E32-LD11N 2M are for glossy white paper).

With Retro-reflective Models, objects with a high reflection factor may cause the Fiber Sensor to detect reflected light as incident light. Also, stable detection may not be possible for transparent objects. Check suitability beforehand.

•

You can easily mount these Fiber Units by making a hole in the bracket and

tightening just one nut.

•

The cable follows the wall, so extra space is not required, and the cable will

not get caught on other objects.

A Fiber Unit with Build-in Lens is the new standard in fiber units.

We recommend this new standard Fiber Unit that achieves stable

detection with a high-power beam.

You don’ t have to worry about the lens falling off and getting lost.

Through-beam Flat Fiber Units are also available. (→ 14 page)

Retro-reflective Models are ideal for detection

of transparent objects.

What Is “Flexible” Fiber?

Structure which

has a cladding

around a large

number of ultrafine

cores.

Features of Coaxial Reflective Type

These Fiber Units offer better detection of small objects at close distances

(of 2 mm or less) than Standard Reflective Fiber Units.

They also detect glossy surfaces more reliably than Standard Reflective Fiber Units,

even if the surface is tilted.

The receiver fibers are arranged around

the emitter fiber as shown below.

The flexible fiber has a small bending radius for easy routing without easily breaking.

It is easy to use because the cable can be bent without significantly reducing light intensity.

Note:

There is a white line on the emitter fiber.
