Product Description
LK-2001 is an LK Series controller that is manufactured by Keyence. This controller is a high-precision model and the reference distance is 30 mm. The measuring range is plus or minus 5 mm. The light source is a visible red semiconductor laser with an output of 0.95 mW and a wavelength of 670 nm. The sampling cycle is 512 μs. This controller is associated with the LK-031 sensor head. The housing is made of polycarbonate and the weight, including the cable, is approximately 515 g. The current consumption is 400 mA (maximum). The enclosure is rated IP67.
The connections available on the LK Series controller include the laser emission stop input (laser emission stops immediately when this terminal is disconnected from the GND terminal), the synchronous (timing) input (the analog output value just prior to the synchronous input is retained when this terminal is connected to the GND terminal, and laser emission is stopped), the auto zero input (the analog output to 0V (12 mA) is reset when this terminal is connected to the GND terminal, the alarm output (when measurement is impossible due to insufficient or excessive light quantity, or due to the target being out of the measuring range, the output contact opens), the near alarm output (when a target is positioned closer than the measuring range, the output contact opens), the far alarm output (when a target is positioned further than the measuring range, the output contact opens), the analog voltage output (a voltage of the full measuring range ± 5V is output. When measuring is impossible, 12V is output), and the analog current output (a current of 4 to 20 mA relative to the full measuring range is output. When measuring is impossible, 31.2 mA is output).
