FU-57TZ Keyence Fiber Optic Sensor Side Beam 1 m Free-Cut Tough-Flex

FU-57TZ Product Overview

The FU-57TZ is a fiber optic sensor unit from Keyence. It belongs to the FU series. The beam exits from the side. The spot size is 0.5 mm. This small spot finds tiny parts and edges.

The fiber cable is 1 m long. You can cut it to fit your machine. The fiber diameter is 1.0 mm. The bend radius is only R2 mm. That Tough-Flex design survives tight routing. It detects objects as small as 0.005 mm.

The unit works from -40 to +50 C. It weighs just 5 g. That low weight suits moving heads and small fixtures. Need a quote? Email sales@powergearx.com or message +86 18030005825 on WhatsApp. We ship in 12 to 24 hours.

Expert Review

The FU-57TZ shines when space is tight. The side beam fits where a straight head cannot. The 0.5 mm spot picks out fine detail. It can sense objects down to 0.005 mm. That suits wafer, wire, and micro-part work. The R2 mm bend radius is the standout spec. You can route it around corners without breaking the fiber. The 1 m free-cut cable lets you trim to size. The 5 g weight adds almost no load to moving parts. The wide -40 to +50 C range handles cold rooms and hot lines. One note: this is a fiber unit only. You must add a separate amplifier. Check your amplifier series before you buy. Pair it with the right one and this unit performs very well.

Manager’s Insight

Keep the FU-57TZ in stock for electronics and semiconductor clients. The tiny spot and side beam solve hard sensing jobs. The Tough-Flex build cuts replacement orders. Buyers with tight machines come back for more. The 1 m cuttable cable fits many setups. That reduces SKU count. Sell it with a matching amplifier and mounting bracket. Bundles lift average order value. Fast FedEx, UPS, and DHL options close urgent deals. A 12-month warranty removes buyer doubt. Hold a few units for same-day needs.

FAQ

Q: Is the FU-57TZ a complete sensor?

A: No. It is a fiber unit only. You need a separate Keyence amplifier to run it. Pick one that matches your FU series setup.

Q: Can I shorten the fiber cable?

A: Yes. The cable is free-cut. Trim it to the length you need. Cut it clean and square for the best light transfer.

Q: How tight can I bend the fiber?

A: Keep the bend at R2 mm or more. The Tough-Flex design allows tight routing. Bends below the limit can break the fiber or cut signal.

Q: What makes the side beam useful?

A: The beam exits at 90 degrees. That lets you sense parts in narrow gaps. It also saves space in crowded fixtures.

Q: How do I clean the fiber tip?

A: Use a soft cloth and mild cleaner. Keep oil and dust off the tip. A dirty tip weakens the signal and causes false trips.

Buying Guide

• Confirm your amplifier works with FU series fiber.
• Check the spot size. The 0.5 mm spot suits tiny targets.
• Plan the cable route. Stay above R2 mm bends.
• Measure your run. The 1 m cable may need trimming.
• Pick PNP or NPN on the amplifier side, not the fiber.
• Add a mounting bracket for stable aiming.
• Order a spare for high-cycle machines.
• Use FedEx, UPS, or DHL for urgent jobs.

Warranty and Delivery

• Every unit carries a 12-month warranty.
• Orders ship in 12 to 24 hours after payment.
• Courier choice: FedEx, UPS, DHL.
• Tracking details go out after dispatch.
