Keyence GL-VM40HP Type 4 Safety Light Curtain
The GL-VM40HP is a compact Type 4 safety light curtain from the Keyence GL-V series. It uses 40 beam axes for hand protection. The PNP output suits many safety circuits. The metal body is small and strong. Therefore, it fits tight machine guards. The transmitter and receiver work as an ESPE / AOPD set. Optical synchronization removes the sync cable. The infrared LED runs at 850 nm. The unit turns ON only when all beams are received. As a result, it protects operators near moving parts.

FAQ
Q: What is the main difference between GL-VM40HP and GL-VM48HN?
A: The GL-VM40HP has 40 beams and PNP output. The GL-VM48HN has 48 beams and NPN output. The GL-VM40HP is 800 mm long. The GL-VM48HN is 960 mm long. Choose based on guard height and controller input type.
Q: How do I know if PNP output fits my machine?
A: Check your safety relay or PLC input card. If it needs a positive switching signal, PNP fits. If it needs a negative switching signal, choose an NPN model. Our team can check this before shipment.
Q: Can I replace an old curtain with the GL-VM40HP?
A: Often yes. First check beam count, height, range, and output type. Then check bracket space and cable length. Send us the old model number. We will cross-check it for you.
Q: Why does the unit not turn ON after wiring?
A: Check supply polarity first. Then check that all 40 beams are aligned. Also check load current and cable resistance. If one beam is blocked, the OSSD stays OFF.
Q: What should I check before buying a surplus unit?
A: Confirm the model number and output type. Ask for test records. Check the housing and front cover. Also confirm cable and bracket supply. Oiltech Controls verifies these points before shipment.
