Product Overview
GL-VM32HP is a compact Type 4 safety light curtain from Keyence, part of the GL-V series. It uses 32 infrared beams for hand protection. Therefore, the metal housing stays small and strong. Moreover, it works well in harsh factory settings. In addition, the unit is easy to install.
This set includes a transmitter and a receiver. Because it uses optical synchronization, wiring stays simple. The detection height is 620 mm. As a result, it senses objects as small as ø25 mm. Response time is fast at max. 5.1 ms. Furthermore, the unit meets IEC61496-1/-2 Type 4, ISO13849-1 PL e, and IEC61508 SIL3. Consequently, it suits high-risk machinery.

Installation Guide
- First, mount the transmitter and receiver facing each other. Then, keep them aligned.
- Use the optical synchronization. As a result, no extra sync wire is needed.
- Check the effective angular aperture. It is up to ±2.5° at 3 m or above.
- Keep the detecting distance between 0.3 m and 15 m.
- For interference prevention, connect up to 2 units in series. Also, use the switch setting.
- Use a 24 VDC Class 2 power supply. Moreover, keep ripple at 10% or less.
- After mounting, verify alignment with the indicator. Consequently, you avoid false trips.
- If alignment is off, adjust the brackets. Then, recheck the indicator.
Setup and Maintenance
- The OSSD turns ON when all 32 beam axes are received.
- Response time is fast. Specifically, it is max. 5.1 ms from ON to OFF.
- The metal housing is IP65/IP67 rated. Therefore, it resists dust and water.
- Clean the front cover with a soft cloth. However, do not use harsh chemicals.
- Check the alignment after shock or vibration. In fact, the unit resists 15 G shocks.
- For best results, inspect the front cover monthly. Similarly, check cable connections often.
- If the indicator blinks, check for blocked beams. Then, clear the obstruction.
Compatibility Notes
- It works as a standalone Type 4 safety light curtain.
- There are no built-in communication ports or protocols.
- The PNP transistor output connects to standard safety relays.
- Series connection supports up to 2 units. Consequently, this helps with interference prevention.
- It is compatible with 24 VDC control systems.
- Because it uses optical sync, no dedicated sync cable is required.
- If you replace an older GL-V unit, check the connector type first. Then, verify pinout.
