2mm Pitch Crimp Type Wire-to-Board Connector: DF51/DF51K Series
In today's industrial equipment market, there's a growing emphasis on manpower-saving and self-actuation technologies, leading to diverse applications like Cooperative Robots, AGVs, AMRs, and Drones. With various internal wiring methods such as PCB mounting, in-line, and branch types, connectors need to offer high reliability to withstand vibration, shock, and environmental factors.
The DF51/DF51K Series provides a solution with its 2mm pitch Crimp type Wire-to-Board connectors, catering to a range of connection needs. These UL/C-UL certified products feature a center lock and side lock for easy handling and a secure connection. They come in various configurations including straight, right angle, DIP, SMT, in-line, branch, single-row, and double-row, with options for gold plating, tin plating, and potting (resin-filled) to safeguard against water, dust, and other contaminants. Additionally, their high contact lance strength ensures that cables remain secure even during wrenching.

Features
Ensuring High Reliability with Specialized Safety Structures
Our connectors feature a specialized structure designed to prevent issues such as incorrect mating and disconnection during assembly, as well as problems caused by fretting corrosion during use.
Applicable to Various Secure Designs for a Wide Range of Equipment
◆Incorrect Mating Prevention Key
Includes a mating mark for visual insertion direction confirmation.
◆Positive Lock Design
Prevents unintended disconnections.
◆Resin Sealing Compatibility (Straight Type Only)
Protects against water or dust intrusion in mounting areas. Supports potting resin up to 3mm.
◆105°C Heat Resistance
◆Fretting Corrosion Measurement
Gold plating type prevents fretting corrosion, making it suitable for applications involving vibration or delivering micro current flow.
Side Lock and Center Lock Types Available (no edits, perfect as-is!)
Choose between side lock or center lock types based on your board layout pattern, especially when using multiple mounting connectors in depth or lateral directions.
Locking Types Available to Meet PCB Layout Requirements
DF51 Series Side Lock
Effective when mounting in the width direction
DF51K Series Center Lock
Effective when mounting side-by-side
Low Profile Design for Space-saving
The DF51 Series features a side lock design, eliminating the need for additional unlocking space on top of the connector. This contributes to reducing the overall system size.
Side Lock Saves the Unlocking Space on the Top of the Connector
Cable Routing does not Interfere with Unlocking as
the Locks are Located at Two Sides of the Connector
Use of Branch Adapter to Simplify Wiring
The DF51 Series offers a branch adapter variation that allows for current branching, simplifying internal wiring and reducing cable clutter in messy applications.
The Use of the Adapter Allows the Current to Branch
*The shunting balance in actual use varies with the resistance ratio of the branch destination.
Ex. Robot Arm
Crimping Tool Compatibility
The crimping tool used for the DF51 Series is compatible with the DF11 Series. If you already have DF11 Series crimp tools, there's no need to obtain new ones; you can continue using your existing crimp tools.
