Overview
The LE-7000 series covers the distance range that a machine frame usually forces on you. Where the LE-6000 expects the head a few centimetres from the part, the LE-7000 starts at 38 mm and goes out to 1144 mm, so the same measurement principle works on a robot wrist and on a gantry over a conveyor.The trade is resolution for stand-off, and the catalogue states it plainly: ±0.6 µm repeat at 38 mm, ±8 µm at 600 mm, ±40 µm at 1144 mm. The profile interval follows the same curve, from 5 µm to 640 µm. Picking a model is therefore an exercise in reading the fixture drawing, not in choosing the most expensive head.Every model shares the 3200-point profile, the 9 µs high-speed mode, native HDR and IP67 sealing. That consistency is the point of the series: a plant can standardise on one interface and one mounting bracket and still cover close-range pin inspection and wide-area panel scanning.
Application scenarios
Rail and profile extrusion
Measures the full cross-section of an aluminium extrusion at line speed.
Robot-guided welding
The head finds the joint and feeds the offset to the robot before the arc starts.
Tyre and rubber profile
Tread depth and sidewall shape on a rotating tyre.
Logistics and volume measurement
The 600–1035 mm models size cartons and pallets on a moving belt.

Dimensions

| LE-7160 | 143.0 × 110.0 × 35.5 mm |

| Laser exit | Bottom face, 35.5 mm behind the front edge |
Every head in the family is 35.5 mm thick, so the same stand-off plate works across the range; what changes is the height of the head and therefore the working distance you have to leave in front of it.

How to specify
- 01
Fix the range first
Triangulation covers a few millimetres to about a metre with µm resolution; beyond that the time-of-flight models take over at millimetre resolution. Do not ask a 10 mm-range sensor to measure at 500 mm — the spot has already walked off the receiver.
- 02
Check what the spot lands on
A shiny machined face sends the beam away from the receiver, a black rubber part absorbs it, and a transparent film lets it through. Blue-laser models are the answer for hot, red-glowing or organic surfaces; a 45° mounting removes most mirror reflections.
- 03
Choose the interface from the controller
Analogue for a fast control loop, RS485 when several sensors share one bus or when the reading has to be logged, switching output for a simple go/no-go.
- 04
Allow for the environment
A 1 µm sensor is only as good as its bracket. Thermal growth of an aluminium bracket over 10 °C is more than the repeatability of the sensor; use cast iron, granite or a short, stiff bracket.
Why this series
One platform from 38 mm to 1.1 m
The mechanical mounting, the interface and the software are the same across all ten heads. You choose the reference distance the machine allows and keep the integration work you already did.
9 µs sampling at 3200 points
High-speed mode shortens the exposure to 9 µs, which freezes motion on a fast transfer instead of smearing the profile across the scan.
Accuracy that tracks the range
Repeat accuracy moves from ±0.6 µm at 38 mm to ±40 µm at 1144 mm — roughly linear with the stand-off. The table above is the honest way to pick a model: start from the distance the fixture gives you.
Questions
How do I choose between LE-7060 and LE-7062, which have the same 62 mm distance?
The 7060 has a wider profile interval (10 µm against 5 µm) and a looser linear accuracy (±0.05 % against ±0.1 % F.S.). The 7062 is the finer of the two; the 7060 is the faster, more tolerant one. If in doubt, the 7062 matches the 7040's interval and keeps the software settings identical.
Can the LE-7000 heads be used outdoors?
IP67 covers dust and temporary immersion, but the quoted ambient range and the laser class assume a machine enclosure. Direct sunlight on the part will swamp the detector; use a shade or a band-pass filter hood.
Do all ten models use the same cable and connector?
Yes. The electrical interface is common across the series, which is why a spare head can be swapped between a 38 mm and a 600 mm station without changing the harness.
