*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. 

Combined Fiber Amplifier Units

Series	E3X-HD Series	E3NX-FA Series
Appearance
Output	1 output	1 or 2 outputs (depending on the model)
External input	Not supported	Supported or not supported (depending on the model)
Response time *	50 μs (55 μs)/250 μs/1 ms/16 ms  (Default: 250 μs)	30 μs (32 μs)/250 μs/1 ms/16 ms  (Default: 250 μs)

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.
