Key issues

Question 1: What is the highest resolution of the ZX-L-N series sensor and which model does it correspond to? What are the differences in resolution among different detection methods?

Answer: The highest resolution is 0.25 μ m, corresponding to the ZX-LD30V/ZX-LD30VL retro reflective probe; Due to the detection distance and spot design of diffuse reflection and reflection, the resolution is between 2~12 μ m, and the high-precision mode of short distance regression reflection can reach 0.25 μ m.

Question 2: What are the output types and judgment functions of the amplifier unit, and how do they meet the requirements for different control system connections?

Answer: The amplifier supports dual-mode output of current (4~20mA) and voltage (± 4V/1~5V), with bottom switch switching; Equipped with HIGH-PASS/LOW 3-channel judgment output, with two optional output types of NPN/PNP, it can be directly connected to different systems such as PLC and industrial computer.

Question 3: How to classify the safety levels of ZX-L-N series lasers and what core safety requirements must be followed when using them?

Answer: The reflective type is EN 1/FDA I (safety level), and the reflective type is EN 2/FDA II (low-power visible light); Core requirements: It is forbidden to directly look at the laser, the optical path should be closed to avoid reflection, the protective shell should not be disassembled, and the probe connector should not be plugged or unplugged when powered on.
