This week’s product roundup highlights FFC and FPC connector solutions from top suppliers.
I-PEX Connectors’ DW5 two-way FPC and discrete wire connectors can accommodate 0.2mm-thick (±0.3mm) FPC cables or 34AWG discrete wire using the same PCB and receptacle combination, making them ideal for use in a variety of space-constrained portable electronics, including laptop screens. These versatile, hybrid connectors have a 0.5mm-pitch, an ultralow, 1.1mm maximum mated height, a robust mechanical back-lock that ensures high FPC retention force, and an anti-reversing mating structure that prevents the accidental unmating of discrete wires. They are currently available with six or 10 copper alloy contacts and heat-resistant, UL94 V-0 housings and actuators. Receptacles are packaged on embossed tape and plugs are packaged in trays.
Hirose’s new FH63 Series FPC/FFC connector delivers high-speed data transfer in a rugged, high-reliability design that’s resistant to high temperatures (up to 105°C), shock, vibration, humidity, corrosion, and hydrogen and sulfur gasses. Ideal for harsh-environment applications in the automotive market and beyond — including navigation, laser and millimeter wave radar, in-vehicle camera systems, gaming consoles, industrial control units, medical devices, notebook PCs, and TVs — the series is currently available in 30- and 40-position versions with a 0.5mm pitch and 2.8mm height profile. Its two-point contact design has two independent springs with wiping action that prevents failures resulting from dust, dirt, and other contaminants, its wide tapers enable smooth FPC insertion, and its single-action lock simplifies assembly and emits a clear, tactile click to confirm proper insertion. It supports USB 3.0, Embedded DisplayPort v1.3, and HDMI 1.4a standards and up to 5.4Gb/s transmission, accepts shielded FFC for EMI protection, is RoHS compliant, and meets halogen-free requirements.
Amphenol ICC’s AutoLock FPC connectors have a 0.5mm pitch, a 2.5mm height profile, an auto-locking mechanism that establishes reliable, high-retention-force connections with FPC cables, and a mistake-proof poka-yoke insertion mechanism that ensures full FPC engagement, provides robust resistance to shock and vibration, and requires a secondary action for FPC removal.

The Zero-Insertion-Force (ZIF) FFC assemblies offer 0.5mm, 1mm, and 1.25mm pitches and either traditional tape-back ZIF or ZIFLOC overmold for enhanced reliability.
TE Connectivity’s flexible printed circuit (FPC) connectors are ideal for applications that demand lightweight, low-profile solutions with small centerline or pitch spacing, including: tablets, personal computers, mobile and smartphones, wearables, cameras, GPS, set-top boxes, game consoles, LCDs, disk drives, printers, copiers, and medical devices. Currently available in five centerline spacing options: 0.25mm, 0.3mm, 0.5mm, 1mm, and 1.25mm, these cost-effective interconnects use a robust actuator to secure FPC and FFC cable terminations, enabling reliable, tool-less, field-terminable connections. The FPC product family also offers options including: ZIF and non-ZIF styles, tin/lead or lead-free plating, SMT and through-hole PCB terminations, right-angle and vertical mounting orientations, slanted insertion capabilities, solder pads and kinked legs for PCB retention, and various flip-locks, contact points, and actuator types.
Newark element14 stocks Easy-On™ zero-insertion-force (ZIF) FFC/FPC connectors from Molex.
