H2EDGRH-2.5 Pcb board terminal blocks

H2EDGRH-2.5 Pcb board terminal blocks

High density connection: The double row structure provides a large number of connection points in a limited space.

Stable connection: After being inserted into the mother seat, it is fixed by buckles or friction, and the connection is firm, able to resist certain vibrations and pulling.

Modular design: facilitates the modular design and production of PCBs, facilitating assembly, testing, and maintenance.

Good guidance: The mother seat usually has a foolproof design to prevent reverse insertion.

Horizontal connection: The bent pin design saves vertical space above the PCB, making it ideal for parallel connections or stacked structures.

Typical application scenarios

This type of terminal is widely used in various electronic devices and industrial control fields due to its reliability and convenience:

Industrial control: PLC (Programmable Logic Controller), servo drives, I/O modules.

Power supply: Input/output interfaces for switch mode power supply and UPS with different power outages.

Communication equipment: board connections inside routers and switches.

Instrumentation: data acquisition cards, testing and measuring equipment.

How to use and match components

Welding: Insert the solder pins of the bent pin terminals into the corresponding through holes on the PCB, and then fix them on the board through wave soldering or manual soldering.

Docking: Select a double row female socket (rubber shell socket) with a spacing of 2.5mm that matches it. Crimp or solder one end of the female socket onto the wire, then directly align it and insert it into the bent pin terminal. If you hear a "click" sound or feel stuck, it means the connection is in place.

Home appliances and consumer electronics: the connection between the control board and display board or sensor of some large home appliances.

The 2.5mm double row socket bent pin terminal block is a compact and reliable PCB board wiring connector. Its 2.5mm spacing and double row curved needle design are its most prominent identification, making it an indispensable role in electronic devices that require horizontal and high-density connections. When selecting, in addition to spacing and number of rows, attention should also be paid to parameters such as number of rows (e.g. 2xN, where N represents the number of pins per row), total number of pins, current rating, and operating temperature.

9.TERMINAL BLOCK FAQ

Q1: What are the practical advantages of 2.54mm dual-row bent pin terminal blocks?

A: Dual-row bent pin terminals greatly increase wiring density on limited PCB space. Compared with single-row models, they double the connection points in the same footprint. The bent pin design fits side installation perfectly. It avoids height interference inside compact control cabinets, which is a common pain point in vertical pin layouts.

Q2: Are 2.54mm dual-row bent pins reliable for long-term industrial operation?

A: Yes, they deliver stable industrial-grade performance. Qualified bent pins adopt knurled and rivet fixing structures. This prevents pin loosening during wave soldering or long-term equipment vibration. In actual cabinet debugging, well-machined dual-row bent pin blocks show consistent soldering quality and low failure rates.

Q3: Does dual-row 2.54mm bent pin layout affect electrical safety and clearance?

A: No, if manufactured with standard 2.54mm pitch spacing. Professional dual-row terminals maintain qualified creepage distance and insulation gaps. The internal barrier structure prevents crosstalk and short circuits. Even with dense wiring, it meets regular low-voltage industrial safety requirements.

Q4: Can 2.54mm dual-row bent pin terminal blocks pass standard wave soldering?

A: Absolutely. Industrial-grade models use high-temperature PA66 housing and tin-plated copper pins. They support conventional wave soldering processes. The unified coplanarity design ensures uniform soldering on dual rows, reducing empty solder or cold solder issues during mass production.

Q5: What scenarios are ideal for 2.54mm dual-row bent pin terminal blocks?

A: They are best for space-limited industrial control boards, IoT devices, and mini PLC modules. The bent pin side-exit design works well for narrow cabinet installations where top vertical pins will clash with the enclosure. Engineers commonly use them to optimize compact panel wiring and save overall PCB layout space.
