GL-R39F Keyence Safety Light Curtain | GL-R Series Type 4, Finger Protection, 39 Beams
The GL-R39F is a Type 4 safety light curtain from the GL-R series. It ships as a transmitter and receiver set. The pair forms a Type 4 ESPE/AOPD system. Detection capability is ø14 mm for finger protection. It carries 39 beam axes with 10 mm spacing. Detection height reaches 380 mm. Total length is 400 mm. Detecting distance spans 0.2 to 10 m. OSSD response time is max 8.6 ms. The infrared LED runs at 870 nm. Synchronization works by optical or wire method, set by wiring. Active production confirmed as of 2026-09.
Oiltech Controls’s Insight
- The GL-R39F protects fingers at a 14 mm resolution.
- Because response time is 8.6 ms, safe stop distance stays short.
- Also, IP65/IP67 rating handles washdown and dusty cells.
- As a result, it suits tight guard openings on small machines.
- Furthermore, optical sync cuts wiring between transmitter and receiver.
Oiltech Controls Review
- Strong pick for press, robot, and assembly guarding.
- Because it meets PLe and SIL3, safety relays pair easily.
- Also, two GL-R systems can run side by side with channel switching.
- However, OSSD type depends on cable. Order the right one.
- As a result, it drops into existing GL-R guard designs.
Best Fit Equipment
- Safety relays and safety controllers
- Press brakes and hydraulic presses
- Robot cells and pick-and-place stations
- Palletizers and packaging guards
- Muting and AUX lamp circuits

FAQ
Q: How do I choose between optical and wire synchronization?
A: Use optical sync to save wiring runs. Choose wire sync when beam crosstalk or dirty lenses cause unstable optical sync.
Q: Can two GL-R39F pairs run near each other?
A: Yes. Up to 2 GL-R systems can share a space. Set channel A/B for optical sync, or rely on automatic switching for wire sync.
Q: What cable do I need for PNP or NPN OSSD?
A: The cable type sets PNP or NPN. Therefore, confirm your safety relay input type before ordering the cable.
Q: Is the GL-R39F suitable for outdoor use?
A: It handles 20,000 lux sunlight and IP67. However, add a sun shield if direct light hits the receiver lens.
Q: What should I check before buying a used GL-R39F?
A: Confirm all 39 beams align, OSSD switching works, and lenses are clear. Also, check the cable for cuts. Oiltech verifies each unit before shipment.
