FAQ
Q: Is the GL-VM22LP a hand or body protection curtain?
A: It is a body protection curtain. Beam spacing is 40 mm. Minimum object size is ø45 mm.
Q: What output does it provide?
A: It provides PNP transistor OSSD x2. Confirm your safety relay accepts PNP signals.
Q: Can it detect a hand?
A: No. It detects objects down to ø45 mm. For hand detection, pick a model with 20 mm spacing.
Q: How do I choose the right length?
A: Match the 880 mm total length to your opening. The 840 mm detection height covers most body access zones.
Q: Is the response time suitable for a fast line?
A: The OSSD reacts in max. 4.8 ms. Check this against your machine stop time before mounting.
