22 (20 + 2 Power) Position Connector Header, Outer Shroud Contacts Surface Mount Gold The BM24-20DP/2-0.35V(51) is a board-to-board and board-to-FPC header connector manufactured by Hirose Electric. It belongs to the BM24 series, a family of fine-pitch hybrid power and signal connectors designed for applications that require both data signaling and supplementary power delivery within the same compact interconnect, eliminating the need for a separate dedicated power connector alongside the signal interface. The connector functions as the plug (header) half of a mating pair, intended to mate with a corresponding BM24 receptacle to join two printed circuit boards, or a printed circuit board and a flexible printed circuit, in a low-profile board-to-board arrangement. This part number designates a configuration with a defined signal contact count supplemented by additional dedicated power contacts, reflecting the series' hybrid design philosophy in which the majority of positions handle signal or data lines while a smaller subset of positions is reserved for carrying higher current to support onboard power rails. This arrangement is particularly useful in compact consumer devices such as smartphones, wearables, and camera modules, where both data interfaces and local power distribution must be routed across a board-to-board junction without dedicating separate connectors to each function. The series is positioned by Hirose as supporting high-speed signaling standards including USB interfaces, making it suitable for applications that combine high-speed data transmission with power delivery in a single compact connector footprint. The connector's fine contact pitch and low mated height make it well suited to thin, space-constrained form factors where minimizing both footprint area and stack height is a priority. As with other Hirose board-to-board offerings, the connector is non-polarized in its base mechanical design, and it is supplied on embossed carrier tape for automated pick-and-place assembly, with construction compliant to RoHS material restrictions. Mechanically, the header is built to withstand the repeated mating cycles typical of consumer electronics manufacturing, rework, and field service, while maintaining stable, low-resistance contact across both its signal and power contact paths under realistic vibration and thermal conditions. As a header-style connector, it is intended to be soldered directly to a host PCB, with its mating receptacle counterpart soldered to the opposing board or FPC, allowing the assemblies to be joined and separated as needed throughout the product lifecycle.

Ethernet Controller 10/100 Base-T/TX Bus Interface 80-TQFP-EP (12x12) The LAN9254-I/JRX is an EtherCAT SubDevice (slave) controller developed by Microchip Technology, designed to serve as the communication backbone for industrial automation devices participating in an EtherCAT network. The device integrates dual Ethernet physical layer transceivers directly on-chip, eliminating the need for external PHY components and simplifying the design of EtherCAT-enabled equipment such as servo drives, sensors, I/O modules, and other field devices used in real-time industrial control systems. Architecturally, the controller can operate as either a two-port or three-port node, depending on the network topology required. In its standard configuration it functions as a two-port device supporting daisy-chain connections typical of EtherCAT line topologies. When configured as a three-port device, it gains an additional management interface port that can connect to an external PHY or to another LAN9254, enabling star or tree network topologies and allowing the device to act as a branching point within a larger EtherCAT installation. Each integrated Ethernet PHY operates in full-duplex mode and supports automatic crossover detection, so the device can use either straight-through or crossover cabling without requiring manual configuration. Beyond pure protocol handling, the LAN9254 includes a substantial set of general-purpose digital input and output lines, allowing it to be used in simple field devices without requiring a separate microcontroller. For more complex applications, the device communicates with an external host processor through an integrated host bus interface that behaves like simple memory-mapped SRAM, supporting both 8-bit and 16-bit data widths along with multiple byte-ordering conventions, which makes it straightforward to interface with a wide range of microcontroller and microprocessor architectures. Internally, dual process data RAM buffers manage the exchange of real-time process data between the host application and the EtherCAT communication engine, while a dedicated interrupt line notifies the host of relevant internal events. A key feature of the device is its built-in distributed clock mechanism, which provides high-precision timing synchronization across all nodes in an EtherCAT network. This capability is essential for motion control and other applications where multiple devices must act in tight temporal coordination. The controller also provides configurable status indication through standard network activity and link LEDs, along with optional error and run-state indicators that give visibility into the health and operational state of the device at a glance. Power architecture on the LAN9254 is simplified through an integrated linear regulator, allowing the device to be operated from a single primary supply rail while internally generating the lower voltage needed for its core logic. This reduces the external power supply complexity that would otherwise be required to support separate core and I/O voltage domains. The "-I" designation on this particular part number indicates an industrial-grade temperature rating, making it suitable for deployment in factory floor and other demanding industrial environments where extended thermal range and long-term reliability are required. The device is housed in a surface-mount package consistent with dense industrial control board layouts and is compliant with RoHS material restrictions.

100 Position Connector Receptacle, Center Strip Contacts Surface Mount Gold The DF40C-100DS-0.4V(51) is a board-to-board and board-to-FPC receptacle connector manufactured by Hirose Electric. It belongs to the DF40 series, a family of fine-pitch stacking connectors intended for compact, high-density interconnect applications such as mobile devices, cameras, wearables, and other space-constrained electronics. The connector functions as the receptacle (socket) half of a mating pair, designed to stack with a corresponding DF40 plug header to join two printed circuit boards, or a printed circuit board and a flexible printed circuit, in a low-profile vertical arrangement. This particular part number represents the full-position, low-profile variant within the series, configured without a reinforcing metal fitting and without a locating boss or mechanical holddown feature, meaning it relies on the contact array itself rather than additional structural hardware for mechanical retention during reflow and handling. The connector is supplied in straight, surface-mount form and is non-polarized, so it can be inserted in either orientation relative to its mating counterpart. Contacts are arranged in parallel rows along the connector body, with gold plating in the contact mating area to ensure reliable signal continuity and resistance to oxidation over repeated use. The series is positioned by Hirose as a general-purpose, high-speed-capable interconnect, suitable for a range of differential and single-ended signaling standards used in consumer and industrial electronics, with the broader DF40 family supporting interfaces such as USB, MIPI, SATA, and PCIe. Its low stacking height and fine contact pitch make it well suited to applications where board-to-board spacing must be minimized, such as camera modules, display modules, or stacked daughterboard architectures in handheld and wearable products. The connector is packaged on embossed carrier tape for automated pick-and-place assembly, and its construction is compliant with RoHS material restrictions. Mechanically, the connector body is built to support repeated mating cycles typical of consumer electronics assembly and rework, while maintaining stable electrical contact under vibration and thermal cycling across its rated environmental range. As a stacking-style connector rather than a card-edge or cable-mount type, it is intended to be soldered directly to a host PCB pad pattern, with the mating plug soldered to the corresponding board or FPC, allowing the two assemblies to be joined and separated as needed during manufacturing, test, or service operations.
