Key questions and answers

Question 1: What is the core difference between Z4M-W40 and Z4M-W100?

Answer: The two models have different measurement center distances, ranges, resolutions, response speeds, and spot sizes; Z4M-W40 has a center distance of 40mm, a range of * * ± 10mm * *, and a maximum resolution of 1.5 μ m; Z4M-W100 has a center distance of 100mm, a range of * * ± 40mm * *, and a maximum resolution of 8 μ m, suitable for different measurement distances and accuracy scenarios.

Question 2: What are the situations where the linear output of Z4M sensor is locked at 6~8V?

Answer: There are three situations: ① a delay period of 3-10 seconds after power on; ② The measured object exceeds the measurement range; ③ Enable the output to be turned off.

Question 3: What are the requirements and protective measures for the safe use of Z4M laser?

Answer: Belonging to FDA IIIb/IEC 3B laser products, direct viewing of the beam is prohibited; The safe distance is about 1m for W40 and 2m for W100. The Z49-SF2 safety kit needs to be installed, and the laser can be controlled using a key switch and interlock terminal. The equipment must be labeled with FDA warning labels to prevent mirror reflection from entering the human eye.
