Oiltech Controls Review

• GL-VM26LP is built for body access zones, not finger-level protection.
• The 40 mm beam spacing matches torso and limb detection.
• Because it uses optical sync, alignment takes minutes, not hours.
• Moreover, the 5.0 ms response suits medium-speed machinery.
• As a result, it fits robot cells and palletizing gates.
• In addition, PNP output matches most European PLC inputs.

Oiltech Controls’s Insight

• Do not confuse body protection with hand protection.
• The ø45 mm object size is larger than the GL-VM32HP ø25 mm.
• Therefore, it is not a finger-detection device.
• Because beam spacing is 40 mm, mounting tolerance is wider.
• In addition, IP65/IP67 sealing handles washdown areas.

Suitable Equipment

• Robot cells with full-body access
• Palletizing and depalletizing stations
• Large conveyor entry and exit zones
• Automated storage and retrieval systems
• Packaging lines with wide openings
• Material handling gates

Installation Notes

• First, mount the transmitter and receiver face to face.
• Then, align them until the indicator turns ON.
• Keep the distance between 0.3 m and 15 m.
• For two-unit setups, use the series connection and switch setting.
• Use a 24 VDC Class 2 supply. Moreover, keep ripple under 10%.
• After shock or vibration, recheck alignment. Then, clear any blocked beams.

Maintenance and Diagnostics

• The indicator ON means all 26 beams are received.
• If any beam is blocked, the OSSD turns OFF.
• Short-circuit and surge protection protect each output.
• Supply reverse-connection protection avoids wiring damage.
• Clean the front cover with a soft cloth. However, avoid harsh chemicals.
• Inspect the cover monthly. Similarly, check cable connections often.

FAQ

Q: How do I know if GL-VM26LP is the right protection type?

A: Check what body part can reach the hazard. If only fingers can enter, this is not the right model. GL-VM26LP detects ø45 mm objects. Therefore, it suits body and limb access, not finger-level guarding.

Q: Can I use GL-VM26LP for hand protection on a small press?

A: No. The 40 mm beam spacing is too wide for hand protection. For hand protection, choose the GL-VM32HP with 20 mm spacing. That model detects ø25 mm objects and meets hand protection rules.

Q: What is the main difference between GL-VM26LP and GL-VM104HN?

A: GL-VM26LP has 26 beams and 1000 mm detection height. GL-VM104HN has 104 beams and 2060 mm detection height. Therefore, pick GL-VM26LP for shorter body access zones. Pick GL-VM104HN for long openings.

Q: Does the PNP output work with my safety relay?

A: Yes. The PNP transistor output works with most safety relays rated Category 4, PL e. However, keep the load under 150 mA. Also, check the relay input type before wiring.

Q: What should I check before ordering a replacement unit?

A: First, confirm the model number on the old unit. Then, check the output type (PNP or NPN). Also, measure the opening height. Finally, verify the connector type. These steps avoid wrong orders.
