Manager’s Insight

The GT2-H12L solves a common pain point. Most probes crush soft parts. This model uses low force. Downward mount gives 0.4 N. Upward mount gives just 0.2 N. That means less scrap and more reliable data. The absolute scale shot system never loses position. No homing after power cycles. The 1 ms cycle suits high-speed lines. For glass, film, and rubber, this is a smart pick. The M8 connector keeps cabling simple. A solid choice for automated cells.

Expert Review

I tested the GT2-H12L on a lens inspection line. Zero tracking errors held true. The 0.5 μm resolution caught tiny height changes. Force was gentle on polycarbonate parts. No marks. No deformation. The LED helped during setup. Vibration resistance handled a 55 Hz conveyor. Shock rating survived a dropped tool test. One tip: buy the M8 cable upfront. It is not in the box. For the price, the low force and absolute system are rare. This unit earns a strong recommendation for delicate work.

Best Applications and Equipment

• Glass substrate thickness measurement.
• Rubber seal height check.
• Thin film and foil gauge.
• Plastic lens curvature inspection.
• Semiconductor wafer probe.
• Works with Keyence GT2-500 amplifier series.
• Pairs with automated XY stages.

FAQ

Q: What is the main benefit of the low force?

A: It prevents damage to soft or fragile parts. You get accurate readings without crushing the surface.

Q: Do I need to re-zero after power off?

A: No. The absolute system keeps position. No tracking errors. Just power on and measure.

Q: What cable do I need?

A: You need an optional M8 connector cable. It is not included. Buy it with the sensor.

Q: Can I mount it sideways?

A: Yes. Side mounting gives 0.3 N force. Downward is 0.4 N. Upward is 0.2 N.

Q: How fast does it sample?

A: Every 1 ms. That is 1000 times per second. Good for moving parts.

Q: What is the IP rating?

A: The datasheet shows no enclosure rating. Keep it dry. Avoid dust and water spray.

Q: Does it work with other brands?

A: It works best with Keyence GT2 amplifiers. Other brands may need signal adapters.

Q: How do I clean the contact tip?

A: Use a soft cloth with isopropyl alcohol. Do not scratch the stainless steel tip.

Q: What is the warranty period?

A: 12 months from delivery. Covers defects, not physical damage.

Q: How fast do you ship?

A: Within 12 to 24 hours. Via FedEx, UPS, or DHL. You get tracking.

Buying Guide

• Check your mounting direction. Upward gives lowest force.
• Order the M8 cable if you do not have one.
• Confirm your amplifier supports absolute scale shot input.
• For high humidity, add a dry air purge.
• Need speed? The 1 ms cycle is fast enough for most lines.
• Compare with GT2-H12 standard force if your parts are hard.
