Measure the velocity and length without contacting moving target to prevent staining and damaging with high-speed up to 100 G of acceleration and features a depth detection range of ±15 mm.
Find out how it has nearly tripled the lifespan of our customer Daikure’s steel processing machine blades, while significantly reducing time and labour costs.
Perform precious measurement of moving target without staining/damaging objects.
Tracking fast acceleration (up to 100 G) by Canon Original Profile machining technology.
No need for safety precautions to protect against laser radiation.
It covers a wide range of products, including steel, paper, wire rods, housing materials, textiles, food products (chocolate, cheese, etc.), concrete, asphalt, and pedestrian crossings.
However, the measurement accuracy varies depending on the surface condition of the object. We recommend that you conduct a demonstration in advance.
These include glossy paper, slippery surfaces, fine threads, and cables, transmitting films, glass, and surfaces where the edges of the fluorescent light are clearly visible on the measuring surface.
It's possible. However, if the object is too thin, you may not be able to see the surface well.
Stable measurement is possible for diameters of about 40 mm or more. However, the measurement accuracy varies depending on the surface condition of the object. In some cases, diameters of Φ40 mm or less can be measured, but this will affect the measurement accuracy.
It has no impact in general use.
Yes, you can. The standard is IP65 compliant. Please attach a special cable and a special cap that is dustproof and waterproof.
It can be measured without any problems. In addition, if there is a possibility of oil adhering to the PD series, we recommend using the optional protective cover unit.
There is no problem with some vibration. However, the less vibration there is, the better the accuracy of the measurement.
It is recommended to devise the mounting position and jig of the PD series to measure.
There is a possibility that it can be measured well by changing the measurement mode. For details, please refer to "Mode Function".
If warning still occurs, it may be possible to measure by reducing the amount of reflected light using the ND filter provided by the customer.
Connect the I/O cable from the PD series to the external Programmable Logic Controller (PLC) or sequencer to count the pulse signals from PD series.
Counting the pulses detected by the external PLC or sequencer, and then send a trigger signal to the cutting equipment.
Line driver output. In addition, there are GND, error signal, warning signal, reset signal, and trigger input signal.
Counting the pulse signal. Please note that the PD series does not provide an analog output.
Please select a device that can capture line driver signals. The PD series outputs a pulse signal according to the amount of movement.
As the speed increases, the pulse frequency becomes high, so a high-speed counter is required.
Mitsubishi Electric’s CC-Link high-speed counter unit AJ65BT-D62D does support line driver input.
If the pulse width setting is at the default of 10 um, it will be 4 m/s → 400 kHz, which matches the maximum speed of this counter. But, if the pulse width setting is reduced, it will exceed the maximum range, so caution is advised.
The AJ65BT-D62 does not support line driver input, so it cannot be used for PD series.
Use a PLC to capture the pulse signal of the PD series and convert it to speed.
The PD series has only a line driver output, but the laser doppler speedometer has a BNC pulse output, a BNC analog output, a line driver output from the D-SUB connector, and an open collector output.
There are step shapes and pulse shapes. The voltage is 5~24 V, and the pulse width is more than 0.1 s.
No. Please understand that it is a basic software intended for evaluation purposes.
It is possible to support from application software V1.2 and main unit firmware V1.1 onwards. Please check [Help] → [Version] in the menu bar of the app software.
There are two measurement methods.
We recommend once a year.
Please contact your dealer.
There are no replacement parts other than the LEDs. It is recommended to install a replaceable protective cover unit to prevent dirt and scratches from getting on the lens surface. If the lens surface gets dirty, clean it with a soft cloth to prevent scratches.
Depending on the usage environment, it will be about 10 years.
The actual measurement area is 4.8 x 0.2 mm within the Φ30 mm illumination light. If alignment is difficult, use a measuring distance adjustment tool (optional).
No. The PD series is a measuring device that calculates the distance and speed of an object. Measured values can be output by A/B phase pulses, so please connect them to your PLC and use them in the production line system.
When measured at 40 Hz, it can be measured continuously for 600 seconds. If it is measured at 4 KHz, it can be measured continuously for 200 seconds.
Install within a range of 70 mm ± 15 mm from the object.The closer it is to 70 mm, the more accurate the measurement can be. It is recommended to use a measuring distance adjustment tool (optional) to accurately adjust the alignment.
Accuracy depends on the surface condition of the object and the measurement environment.
If you press the measurement ‘start’ and ‘end’ buttons while the measurement target is moving, you will not be able to measure correctly. It is recommended that you start the measurement with the object stationery.
