About the LK-2111
LK-2111 is a Standard Controller that is manufactured by Keyence for the LK Series. The sensor head that is associated with this controller model is LK-86. This controller weighs 515 grams with the cable and is made out of polycarbonate. 80 mm is the reference distance. ± 15 mm is the measuring range. A visible red semiconductor laser is the light source. Under the light source umbrella, 0.95 mW is the output, 670 nm is the wavelength, and Class II/2 is the laser class. The spot diameter for the associated sensor head is approximately 70 x 1100 μm. 3 μm is the repeatability and ± 0.1% of F.S. is the linearity. 40 mA (maximum) is the current consumption. 1024 μs is the sampling cycle.
The controller includes a SHIFT adjustment key, an AUTO ZERO/RESET key, a SPAN adjustment, indicators (TIMING, STABILITY, DARK, BRIGHT, LASER ON), a sensitivity setting switch, a sensor head connector, and DIP switches (set alarm-hold function, key-lock function, averaging function). Functions on the controller include the response speed selection function, the LFTC circuit, the AUTO GAIN function, the ANALOG OUTPUT HOLD function in the alarm condition, the AUTO ZERO key, and the FAR/NEAR output function. The connections on the controller include the analog current output, the analog voltage output, the FAR alarm output, the NEAR alarm output, the alarm output, the AUTO ZERO input, the synchronous input, the laser emission stop input, the F.G., and the 24 VDC input and output.
