24-Contact USB-C with 10,000-Cycle Durability
The Hirose CX70M-24P1 is a 24-contact USB-C receptacle in the CX70M series, specified for USB 3.2 Gen 1 (5 Gbps) data rates. Rated at 20 VAC and gold-plated on the mating contacts, this is a mid-mount horizontal connector that sits flush in a board cutout — the board edge, cutout, surface-mount, and through-hole right-angle mounting options give layout flexibility for thin-profile enclosures. The 10,000 mating cycles rating is the standout spec here: it's an order of magnitude above a typical consumer USB-C port, pointing to a reinforced shell and contact design meant for industrial equipment, kiosks, or test fixtures where the connector sees frequent connect/disconnect duty.
USB 3.2 Gen 1 — Full 24-Contact Complement
This CX70M-24P1 carries all 24 contacts of the USB-C interface, wired for USB 3.2 Gen 1 (formerly USB 3.0). That means the SuperSpeed differential pairs (SSTX, SSRX) on both sides of the receptacle are populated, along with the CC, SBU, and power/ground pins. Compare this to the CX90M-16P, which uses 24 positions but only 16 active contacts — the remaining 8 are dummy pins for a USB 2.0-only implementation. If your design needs the full SuperSpeed lane, the CX70M-24P1 has the contacts to carry it; the CX90M-16P does not.
The CX70M-24P1 supports a hybrid mounting scheme: it can be surface-mounted, through-hole right-angle, or both — the board edge cutout and mid-mount horizontal feature let the connector body sit partially recessed into the PCB edge. This is useful when the enclosure wall is close to the board edge and a standard right-angle USB-C would protrude too far. The solder termination covers both SMT pads and through-hole anchor legs for mechanical retention.
