Oiltech Controls’s Insight

• Body protection needs 40 mm spacing, not 20 mm
• Match NPN output to your PLC input card
• Confirm 840 mm detection height fits the opening
• Check 24 VDC supply and load current first
• Use series connection only when two units are needed

FAQ

• Q: What protection type is the GL-VM22LN?
  A: It is body protection, with ø45 mm minimum object size.
• Q: Why is the spacing 40 mm instead of 20 mm?
  A: Body protection allows larger spacing. The 40 mm gap detects body entry, not fingers.
• Q: What output does this model provide?
  A: It provides NPN transistor output x2, also called OSSD.
• Q: How does it differ from the GL-VM24HN?
  A: The GL-VM24HN is hand protection with 20 mm spacing. The GL-VM22LN is body protection with 40 mm spacing.
• Q: How do I pick the right GL-V model?
  A: Choose by protection type first, then by detection height and output. Body protection suits wide openings. Hand protection suits tighter zones.
