FAQ

Q1: What is the difference between R4M and DS30M models?
A1: R4M series is retro-reflective type, working with TD-08 reflector plate, sensing distance up to 4 meters. DS30M is diffuse reflection, detects objects directly, max 30cm.

Q2: Does it support both DC24V and AC220V?
A2: Separate voltage versions available: DC24V or AC220V, select the variant according to your power supply.

Q3: Is the output relay contact?
A3: Yes, relay contact output, can connect to PLC, indicator light or small load directly.

Q4: Can it work in dusty factory environment?
A4: It has basic dust resistance, avoid heavy oil and thick dust covering the lens for reliable performance.

Q5: Do R4M models need the TD-08 reflector?
A5: Yes, retro-reflective R4M sensors require the TD-08 reflector for normal detection.
