GL-R63F Keyence Safety Light Curtain | Type 4 63 Beam

GL-R63F Keyence Type 4 Safety Light Curtain with 63 Beam Axes

The GL-R63F is a robust Type 4 safety light curtain from the Keyence GL-R series. It ships as a transmitter and receiver set. This finger protection model uses 63 beam axes with 10 mm spacing. Detection capability is ø14 mm, so it catches small fingers near moving parts. The infrared LED runs at 870 nm and supports optical or wire synchronization. Detection height is 620 mm and total length is 640 mm. Working range spans 0.2 to 10 m. OSSD response time is 11.2 ms maximum. Safety ratings cover Type 4, SIL3, SIL CL3, Category 4, and PLe.

Professional FAQ

Q: How do I set the safety distance for the GL-R63F?

A: Use the 11.2 ms response time in your formula. Add machine stop time and finger approach speed. Then verify with a test rod per local rules.

Q: Should I use optical or wire synchronization?

A: Use wire sync on long runs or bright areas. Optical sync works well on short, clean installs. The wiring decides the mode, so plan it early.

Q: Can two GL-R63F sets run side by side?

A: Yes, up to 2 GL-R systems. Set Channel A and B for optical sync. Wire sync handles this automatically. This prevents crosstalk.

Q: What cable type do I need for PNP or NPN?

A: The cable type sets the OSSD polarity. Order the PNP or NPN version to match your safety relay. Check this before you buy.

Q: How do I choose between GL-R63F and a longer GL-R model?

A: Pick the GL-R63F for 640 mm openings with finger protection. Choose a longer model for taller access zones. Match detection height to the opening first.
