GL-VM32HN Keyence Safety Light Curtain – Type 4 Hand Protection
The GL-VM32HN from Keyence is a compact Type 4 safety light curtain. Moreover, it belongs to the GL-V series. In addition, this model uses 32 beam axes for hand protection. Furthermore, the metal housing is small and strong. Therefore, it fits tight machine guards and production cells.
Above all, the GL-VM32HN offers a 620 mm detection height and a 640 mm total length. Moreover, it detects objects as small as ø25 mm. As a result, response time is max. 5.1 ms. Consequently, this helps stop dangerous motion fast. Also, the unit uses optical synchronization. Therefore, no extra sync cable is needed between transmitter and receiver.
This light curtain meets Type 4 ESPE / AOPD standards. For example, it supports Category 4, PL e and SIL3 safety levels. Consequently, it is a good choice for presses, robots, and automated assembly lines.

Installation Guide
- First, mount transmitter and receiver facing each other.
- Then, keep the lens surface clean and free of oil.
- Also, use the 0.3 to 15 m detecting distance range.
- Moreover, align units within ±2.5° at 3 m or above.
- Next, connect 24 VDC Class 2 supply.
- In addition, check NPN OSSD wiring before power-on.
- After that, use series connection for up to 2 units.
- Finally, set interference prevention switch if needed.
Setup and Maintenance
- Optical synchronization removes sync cable checks.
- Moreover, indicator LEDs show power and output state.
- Therefore, response time stays max. 5.1 ms for fast stopping.
- In addition, IP65/IP67 housing allows washdown and dusty areas.
- Likewise, the aluminum alloy body resists impact and vibration.
- Furthermore, no moving parts reduce wear and service needs.
