Product details

31-Position FPC Connector with Slide-Lock ZIF

This is a key dimension for enclosures with limited z-height, such as handheld terminals or panel-mounted displays. The solder retention feature adds mechanical hold during reflow and subsequent cable strain — the connector body stays anchored to the board even when the FPC is tugged during routing or maintenance. The FPC thickness is specified at 0.30 mm, which is the standard for most 0.50 mm pitch FPCs. Using a thicker or thinner cable may compromise the ZIF contact beam pressure or the slide lock engagement.

Current and Signal Duty

The 250 V voltage rating is typical for signal interconnects in low-voltage equipment. In a typical LCD or sensor interface, the per-contact current draw is well below 0.5 A, so the connector operates within its thermal margin.

Frequently asked questions

Is 3-1734839-1 RoHS compliant?

Yes, the 3-1734839-1 is RoHS compliant.

Does 3-1734839-1 have a locking feature?

Yes, it has a slide lock that secures the FPC after insertion — the ZIF mechanism requires no insertion force, and the slide lock prevents the cable from backing out under vibration.

What is the pitch and position count of 3-1734839-1?

The pitch is 0.50 mm and the position count is 31.
