Expert Review

The EH-108 is a solid sensor head for tight metal detection. The shielded design allows flush mounting. That saves space in crowded fixtures. The oil-resistant body suits machine tools and dirty plants. The 0.005 mm repeatability gives steady results. The 1.5 mm stable range fits small targets. The IP67 shell handles coolant and washdown. The 3 m cable cuts extra wiring work. However, it only detects ferrous metals well. For nonferrous targets, check the derating curve first. The unit needs a separate amplifier too. Overall, it is a reliable pick for precise position sensing.

Manager’s Insight

Pick the EH-108 when you need a small, flush-mount sensor. It works well in machine tools and presses. The oil-resistant build lowers failure rates. The high repeatability reduces scrap. The IP67 rating cuts downtime from coolant. It pairs with Keyence amplifier units. Check your target material before you buy. Ferrous metals give the best range. Plan a spare for critical stations. Ask us for a cross-reference if you need a longer cable or a different range.

FAQ

Q: Can the EH-108 detect nonferrous metals?

A: It detects ferrous metals best. For aluminum or brass, the range drops. Check the characteristics curve before you install it.

Q: Does this sensor head work on its own?

A: No. It needs a Keyence amplifier unit. The head connects to the amp through its cable. Then the amp sends the output signal.

Q: Can I mount it flush in metal?

A: Yes. The shielded design allows flush mounting. This helps in tight fixtures and crowded dies.

Q: How does it handle coolant and oil?

A: The body resists oil. The IP67 rating blocks dust and water spray. That makes it good for machine tools and washdown areas.

Q: What warranty and shipping terms apply?

A: We offer a 12-month warranty. Orders ship in 12-24 hours when stock is ready. We use FedEx, UPS, and DHL.

Q: How do I choose the right sensor for my machine?

A: Check your target metal, sensing distance, and mounting space. Then match them to the EH-108 specs. If unsure, send us a photo of your setup. Email sales@powergearx.com or WhatsApp +86 18030005825.

Buying Guide

• Confirm your target is ferrous metal.
• Check you have 1.5 mm of stable range.
• Pick a Keyence amplifier that fits.
• Measure your mounting space.
• Check cable length needs beyond 3 m.
• Plan a spare for critical stations.
• Ask for a cross-reference if you need a different range.
