Keyence GL-VM08HN Safety Light Curtain – Hand Protection, 8 Beams, Type 4
The GL-VM08HN from Keyence (GL-V series) is a compact, robust metal Type 4 safety light curtain. Moreover, it provides hand protection with 8 beam axes and a 25 mm minimum object size. In addition, this transmitter/receiver set uses optical synchronization and infrared LED (850 nm). Therefore, it is ideal for industrial automation, packaging, and machine guarding. Furthermore, its metal housing ensures long-term durability in harsh factory environments. Consequently, it suits both new installations and retrofit projects. Besides, it needs no separate sync cable. Likewise, its compact 160 mm body fits tight spaces.

Installation Guide
- First, mount transmitter and receiver facing each other.
- Then keep alignment within ±2.5° angular aperture.
- Also use optical synchronization – no extra wiring needed.
- Next, connect 24 VDC Class 2 power supply.
- After that, wire OSSD outputs to machine safety circuit.
- In addition, set interference prevention switch for up to 2 units.
- Finally, verify IP65/IP67 seal after installation.
- Meanwhile, check all cable glands for tightness.
- Similarly, confirm all brackets are secure.
- Likewise, test beam alignment with a test rod.
Setup and Maintenance
- First, clean front cover with soft cloth and mild cleaner.
- Then check beam alignment after shock or vibration.
- Also monitor OSSD response time (max. 4.1 ms).
- Moreover, replace unit if leakage current exceeds 0.8 mA.
- In addition, no internal communication ports to configure.
- Finally, use Keyence original cables for best performance.
- Consequently, regular checks extend product lifespan.
- Likewise, keep spare units for critical lines.
- Similarly, log any fault codes for trend analysis.
Compatibility Notes
- First, works with standard 24 VDC control systems.
- Also NPN OSSD outputs – check PLC input type.
- Moreover, series connection allows up to 2 units.
- However, no fieldbus or Ethernet protocol support.
- In addition, compatible with Keyence GL-V series brackets.
- Finally, replace obsolete safety curtains with same beam count.
- Therefore, verify existing wiring before swap.
- Similarly, check mounting hole pattern matches.
- Besides, confirm cable connector pinout is identical.
