Frequently asked questions

Answers to the most common questions about our products and services

It is a laser reference sensor for rotational speed and an angular reference on a rotating component. It detects a reflective mark on that component.

The manual specifies direct connection through AC-1388. Match wiring and sensor power to the instrument; the documented typical supply is 5 VDC at 30 mA.

The documented optical working range is 100–2000 mm. Stabilize and align the sensor so its indicator responds when the reference mark passes.

The manual permits stable manual positioning or a magnetic stand such as AC-525. The stand provides mounting and does not change signal type or measuring range.

The specification lists IP67 and an operating range of −10 to +40 °C. It is a Class 2 laser; do not look into the beam.
