GL-VM30LP Keyence GL-V Series 30-Beam PNP Safety Light Curtain

GL-VM30LP Keyence Safety Light Curtain: 1200 mm PNP Body Guarding

The GL-VM30LP is the PNP counterpart to the GL-VM30LN in the Keyence GL-V series. It uses 30 beam axes across a 1160 mm detection height. The 40 mm beam spacing targets body access, not finger contact. A 1200 mm total length covers full walk-in zones. PNP output suits sourcing PLC inputs common in European and American panels.

Output Type Selection: PNP or NPN

• GL-VM30LP sources positive voltage to the PLC input.
• GL-VM30LN sinks current to 0 V for NPN inputs.
• Pick PNP when your safety relay expects a high signal.
• Pick NPN when your input card pulls to ground.
• Check your panel standard before ordering to avoid rewiring.

Machines and Zones That Suit the GL-VM30LP

• Hydraulic and mechanical press bodies
• Robot cell entry doors and gates
• Palletizer and depalletizer openings
• Large packaging and wrapping machines
• Vertical lift and storage openings
• Legacy GL-V replacements with fixed 1200 mm mounting

Oiltech Controls’s Insight: GL-VM30LP in the Field

• The 1200 mm length fits most standard press guards without adapters.
• PNP output speeds retrofits on European and American control panels.
• Low current draw avoids overloading small 24 VDC supplies.
• Optical sync shortens installation time on long runs.
• Always confirm the 1160 mm detection height against the real opening.

FAQ: GL-VM30LP Engineering and Buying Guide

Q: Can I swap this unit with the NPN version directly?

A: No. The output wiring differs. The GL-VM30LN sinks current, while the GL-VM30LP sources it. Match your PLC input type first.

Q: Is 40 mm beam spacing enough for finger protection?

A: No. Use a 20 mm or 25 mm pitch model for hand or finger detection. This model targets body access.

Q: What safety distance should I plan for?

A: Apply ISO 13855 with the 5.1 ms response time plus machine stop time and operator approach speed.

Q: Can I mount two sets on the same machine?

A: Yes. Series connection and switch setting prevent interference for up to 2 units.

Q: When is refurbished better than new?

A: Choose refurbished when the model is discontinued but the mounting fixture stays. Choose new for warranty-critical production lines.
