Manager’s Insight
Manager’s Insight: The GT-H22 fills a sweet spot. Its 22 mm range is wider than most compact heads. That means fewer mounting changes on mixed part sizes. The TYPE430 steel body takes hits without bending. The NBR dust boot keeps grit off the contact. For shops that run many part sizes, this head cuts setup time.
Expert Review
Expert Review: This is a workhorse head, not a lab tool. The 8 µm repeatability suits general gauging, not sub-micron work. The 8 Hz response fits moderate speed lines. The IP67 seal handles coolant mist and washdowns. Cable is fixed at 2 m. The PVC jacket stays flexible in cold rooms.
Best Fit Equipment and Scenarios
- Automated assembly and press-fit checks
- Part presence and height gauging
- Thickness measurement on metal sheets
- Robotic gripper feedback
- Packaging and fill-level checks
- CNC tool wear monitoring
- Automotive component inspection
FAQ
Q: Does the cable come attached?
A: Yes. The head ships with a fixed 2 m PVC cable. Plan your routing before you mount it. Longer runs need an extension or a controller nearby.
Q: Can I mount this head sideways?
A: Yes. Side mounting gives 1.4 N of force. Upward gives 1.3 N. Downward gives 1.5 N. Pick the force that suits your part.
Q: Will it survive coolant spray?
A: Yes. The IP67 rating blocks dust and water jets. Do not submerge it. Wipe it dry after washdown.
Q: What controller pairs with this head?
A: It works with Keyence GT series amplifiers. Match the connector type before you buy. Check your amplifier manual for head compatibility.
Q: What is the warranty and delivery time?
A: We give a 12-month warranty. Orders leave in 12–24 hours. We ship by FedEx, UPS, and DHL. You get a tracking number.
Q: How do I choose the right sensor head?
A: First, measure your travel needs. Pick a range with some headroom. Second, check repeatability for your tolerance. Third, match the mounting force to your part strength. Fourth, confirm the connector fits your amplifier. Fifth, buy from a seller with a 12-month warranty and fast dispatch.
