E32-T11NF[]

The results of a thorough analysis of the ingress paths of cutting oil show that the deterioration of cable sheaths is a large factor.
The cable sheaths of OMRON’s Oil-resistant Components are made from fluororesin materials to provide maximum protection against the deterioration with a unique new concept. The result is an oil resistance impregnable to even highly aggressive cutting oils.

Fluororesin, which provides superior resistance to corrosion, is used for the outer cable sheath to suppress cable swelling and deterioration and prevent the ingress of cutting oil into the PCB inside the Sensor.

*The Strongest Material: Based on June 2016 OMRON investigation.

In addition to cable sheaths, joints, and moving sections, cutting oil enters most easily in gaps between different materials. OMRON’ s Oil-resistant Components completely block the ingress of cutting oil with a unique structure that does not allow the creation of gaps.

An aluminum ring bushing is compressed and deformed by a set screw to seal the structure by pressing against the fluororesin part of the fiber core. This prevents the ingress of cutting oil from the joined surfaces.

*1. The IP68G is the degree of protection which is defined according to the JIS (Japanese Industrial Standards).
The IP68 indicates the same level of protection as defined by the IEC, and the G indicates that a device has resistance to oil.
Passed OMRON's Oil-resistant Component Evaluation Standards (OMRON's own durability evaluation standards)
(Cutting oil type: specified in JIS K 2241:2000; Temperature: 35 °C max.)
*2. The optical fiber is 2 m long on each side, so the sensing distance is 4,000 mm.
Note:
1. 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)
2. 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.

Note: The Fiber Amplifier Units are not oil resistant.
* These are the response times for super-high-speed mode (SHS), high-speed mode (HS), standard mode (ST), and GIGA-power mode (GIGA).
The value in parentheses for the super-high-speed mode is for a model with a PNP output.
