Mounting and Alignment Guide

• Face transmitter and receiver directly across the opening.
• Plan the guard around 1240 mm detection height.
• Keep distance between 0.3 m and 15 m.
• Use 24 VDC Class 2 supply with low ripple.
• Wire PNP OSSD outputs to a safety relay or safety PLC.
• Use series connection for up to 2 units to avoid crosstalk.
• Keep load wiring resistance at or below 2.5 Ω.
• Recheck alignment after machine service or impact.

Commissioning and Service

• Optical synchronization removes one sync cable from the panel.
• Fast 5.1 ms response helps keep safety distance short.
• Reverse supply, short-circuit, and surge protection cut wiring risk.
• IP65/IP67 housing handles dust and washdown.
• Aluminum and PPS body resists vibration and shock.

Oiltech Controls Review

• The GL-VM32LP is a long, 32-beam curtain. It is built for body protection, not finger or hand detection.
• The ø45 mm object size tells engineers this is a coarse-detection model.
• The 1280 mm length suits tall openings where a short curtain will not cover the hazard.
• PNP output matches many European and American safety relay inputs. Check the input type before ordering.
• The 5.1 ms response is fast for a 32-beam unit. This helps keep safety distance short.
• If the machine uses NPN input, consider an NPN model in the same GL-V series.

FAQ

Q: What is the Keyence GL-VM32LP used for?

A: It guards body access on large machines. It uses 32 beams and a ø45 mm object size. It is not a finger detection model.

Q: How do I choose between the GL-VM32LP and a shorter GL-V model?

A: Check the opening height. The GL-VM32LP covers 1240 mm. A shorter model may leave gaps. Match the curtain to the risk assessment.

Q: My safety relay uses NPN inputs. Can I still use this PNP model?

A: No. The GL-VM32LP has PNP OSSD outputs. Use an NPN model in the GL-V series instead. Always check the safety relay input type first.

Q: What should I verify before ordering a replacement?

A: Check beam count, object size, output type, total length, and detecting distance. Also check the connector and cable length. These items affect fit and wiring.

Q: How fast can Oiltech Controls ship this model?

A: We ship in 24–28 hours after order confirmation. We use FedEx, UPS, and DHL. Tracking is provided after dispatch.
