Light source
Infrared semiconductor laser with a wavelength of 780 nm and an output of 3 mW max.,
class 3B (IEC), class IIIb (FDA),
Spot diameter
1 mm dia. max. (at measurement point)
1 x 2 mm max. (at measurement point)
S o d a e e
The spot diameter is defined by 1/e
2
(13.5%) of the Sensor’s laser beam center. There is
light leakage outside the defined spot, and the environment of the object may influence
sensing accuracy. Reduce the influence of the environment as much as possible.

Range indicators
Note:
The range indicators, located on
Sensor and Amplifier, are also
used as laser warning lights
(green).
Outside range, abnormal volume of light: NEAR indicator and FAR indicator blink.
Near: NEAR indicator is lit.
Measurement point: NEAR indicator and FAR indicator are lit.
Far: FAR indicator is lit.
Stability indicator (amplifier)
Stable operating range: Green
Possible operating range: Not lit
Insufficient or excessive light: Red

It is possible to adjust the linear output of the Sensor to between -5 and 5 V with span
adjustment.
Enable output
NPN open collector, 50 mA max. at 40 VDC, residual voltage: 1 V max.
Laser emission ON input
Short-circuited with the 0-V terminal (residual voltage: 2 V max.): Laser emission is
turned off.
Open (current leakage: 0.1 mA max.): Laser emission is turned on.
Linear output, indicators, and enable output holding function incorporated.
