Output Response Time Discrete Output:
Fast: 3.6 milliseconds ON and OFF
Medium: 10 milliseconds ON and OFF
Slow:
40 milliseconds ON and OFF
Analog Output (-3 dB):
Fast: 250 Hz (1.6 milliseconds average with 1.6 millisecond update rate)
Medium: 40 Hz (10 milliseconds average with 1.6 millisecond update rate)
Slow:
10 Hz (40 milliseconds average with 2.1 millisecond update rate)
Analog Resolution and
Repeatability of Discrete
Trip Point* Fast: 0.06% of sensing distance (<30 microns @50 mm)
Medium: 0.03% of sensing distance (<15 microns @50 mm)
Slow:
0.02% of sensing distance (<10 microns @50 mm)
Analog Linearity* ± 60 microns (±0.002")
Hysteresis (Discrete Output) <0.35% of sensing distance
Laser Control Connect green wire to +5 to 30V dc to enable laser beam; connect to 0 to +1.8V dc (or open connection)
to disable; 250 millisecond delay upon enable.
45.0 to 60.0 mm (1.77" to 2.36")
Adjustments Response speed: push button toggles between 1.6, 10, and 40 milliseconds
Window limits (analog or discrete): TEACH-mode programming of near and far window limits (see
programming procedure). Limits may also be taught remotely via TEACH input (see page 7).
Analog output slope: the first limit taught is assigned to minimum output current (4mA).
Output Protection Outputs are protected against continuous overload and short circuit
Color Sensitivity* <75 microns (0.003") (typical) for white to dark gray ceramic target
Temperature Drift ±7 microns/°C
*Using white ceramic test surface (see Application Notes).
Resolution and linearity specified at 24V dc, 22°C.
