Even for extremely difficult applications such as measuring variations in HDD surfaces or sensing very shiny objects, the HL-C2 sensor functions stably and consistently. By using our unique new optical system, high density light-receiving cells and a cutting edge sampling technology, a wider variety of objects can now be stably measured with greater precision and speed than ever before.

  • Sampling frequency up to 100kHz
  • Unaffected by color or surface condition of the object
  • Small beam spot type: ø20μm to ø400μm / Linear beam spot type: 20×700μm to 400×6500μm
  • Linearity error, max ±0.02% F.S.
  • Compact design
  • Sensing range from 10mm ± 1mm up to 350 ± 200mm

Options:

  • Extension cable (2 / 5 / 10 / 20 / 30m)
  • Neutral density filter

HL-C2 controller

The compact and multifunctional controller unit HL-C2C again shows how powerful this new sensor series is. A flexible combination of controller and sensor heads allows cost-effective service and maintenance. The controller can use measurements taken by the two sensors to instantaneously calculate critical values. The compact touch panel, which is extremely easy to operate, can in turn display such critical values or be used in combination with the controller to calculate results, e.g. for thickness or difference measurement. Moreover, all adjustments and results can be transmitted via USB 2.0, RS232C or Ethernet to a normal PC.

Characteristics:

  • 32-bit RISC processor
  • Analog current or voltage output selectable
  • Simple configuration via touch terminal
  • Up to two laser heads per controller
  • Zero point and offset adjustable
  • Calculation functions integrated
  • RS232C
  • USB 2.0

Optional:

  • Compact console (touch terminal) HL-C2DP-EX
  • Software HL-C2AiM for setting the sensor and monitoring measurement values

    HG-S Measurement Sensor

    Slim unit body

    1. Slim & robust pencil-type sensor unit
    2. Bending-resistant cable even when used for moving parts
    3. Hot-swappable
    4. Plain bearings with 2-point support structure ensure excellent resistance to lateral loads
    5. Resistance to lateral load
    6. High accuracy: The high-precision sensor head has a resolution of 0.1µm and an indication accuracy of max. 1µm for the full range and max. 0.5µm for the narrow range. The high-resolution CMOS sensors measure the amount of movement by reading the glass scales that have different slit patterns at different read positions. This provides accurate measurements even in high-speed measuring operations. It also eliminates mechanical zero position runs when the system has been switched on.
    7. Resistance to upward thrust impact: Even when a sudden upward thrust impact occurs, the resulting load is applied only to the lower section of the sensor unit. The spindle stopper minimizes the impact on the glass scales.
    8. Tip deviation amount of max. 35µm

    LA Measurement Sensor

    Laser thru-beam sensor with analogue output

    This laser sensor operates with a laser "belt" of 15mm width. Nevertheless, an object of ø 0.1mm will be detected over the 500 mm sensing range with a repeatability of approx. 10µm. Adjusting the emitter and receiver is very easy as a positioning monitor leads to the best position. This laser sensor conforms to class 1, so safety measures are not necessary.
