*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 optical fiber is 2 m long on each side, so the sensing distance is 4,000 mm.
*3. 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.
*4. The sensing distances for Reflective Fiber Units are for white paper.
The sensing distances for the E32-LD11N 2M are for glossy white paper.
Note. Objects with a high reflection factor may cause the Retro-reflective Fiber Sensor to detect reflected light as incident light.
Detection may be unstable depending on the type of transparent object. Check suitability beforehand.
