HG-T laser thru-beam sensor for measurements

The laser thru-beam sensor of the HG-T series works with a belt-shaped laser beam with a height of 10mm for measuring an area, e.g. for checking the contours of an edge.

The sensor achieves a repeatability of < 1µm and has a linearity of less than ± 12µm over the whole measurement range.

The thru-beam sensor has a sensing range of 500mm, which means that a larger variety of applications can be realized than with sensors with a shorter sensing range.

The HG-T series comes with two different sensor heads, which only differ in their dimensions. The slim type is 10mm less wide than the standard type and fits well into machines with very limited space.

Standard type:

• Emitter: 8 x 30 x 60mm (W x D x H)
• Receiver: 8 x 30 x 60mm (W x D x H)

Slim type:

• Emitter: 8 x 30 x 60mm (W x D x H)
• Receiver: 8 x 20 x 60mm (W x D x H)

The optional side view mirror makes it possible to deflect the beam by 90°.

To speed up commissioning, the sensor heads are equipped with a beam alignment function. The sensor heads are easy to mount by plugging them into the controller. The controller automatically detects whether the emitter and receiver have been connected correctly.

Thanks to functions like filters, edge detection, light intensity checks and averaging of measurement values (up to 1024), the measurements are very reliable. These functions help you to detect at an early stage when the measuring process does not run smoothly anymore and the system needs to be modified.

• Guiding the sheet edge of battery electrodes
• Checking diameter and position of threads or wires
• Detection of wafers stacked on top of each other
• Guiding of translucent films
• Measuring of drill holes in motor components
• Measuring the thickness of materials such as films or textile webs
• Highly precise measuring and checking of web edges
• Glass substrate positioning
• Measuring of diameters

Sensor head connection cable

The sensor head connection cable has to be ordered separately.

Notes:

1. Where measurement conditions have not been specified precisely, the conditions used were as follows: supply voltage 24V DC, ambient temperature +20°C
2. Current consumption does not include analog current output
3. Linearity F.S. = 16mA, and is linearity with respect to digitally measured values
4. When slave units are connected to the master unit, the maximum sink current / source current of the control output and ambient temperature vary depending on the number of connected slave units.
