FAQ
Q: What object size does the GL-VM32LN detect?
A: It detects a ø45 mm object. This suits body protection, not finger detection.
Q: How many beams does this model use?
A: It uses 32 beam axes with 40 mm spacing. Detection height is 1240 mm.
Q: Is NPN output hard to wire?
A: No. NPN output matches many PLC and safety relay inputs. Check your input type first.
Q: Can I use it on an old machine?
A: Yes. Oiltech Controls supports obsolete control systems. We verify each unit before shipment.
Q: How do I choose between hand and body protection?
A: Use hand protection for finger or hand access. Use body protection for larger openings. The GL-VM32LN fits long openings.
