DF51K-24DS-2C(800) Hirose Electric

The Hirose Electric DF51K-24DS-2C(800) is a 24-position, 2-row receptacle connector from the SignalBee™ DF51 series, designed for free-hanging (in-line) wire-to-board applications. This connector utilizes a 2.00mm pitch and features a female socket contact type with a crimp termination method, ensuring a reliable and secure connection. The housing is constructed from glass-filled Polybutylene Terephthalate (PBT) and is black in color, offering robust insulation and durability. It includes a locking ramp fastening type for secure mating and is rated for an operating temperature range of -55°C to 105°C. Please note that contacts are not included with this housing, requiring separate ordering of crimp terminals. This model is ideal for internal wiring in industrial equipment, office automation, and consumer electronics where a compact, high-reliability interconnect solution is required.

Features

• High-Density 2.00mm Pitch: Enables space-saving board-to-wire connections while maintaining reliable signal integrity in compact electronic assemblies.
• Secure Locking Ramp: Provides a positive latching mechanism to prevent accidental disconnection due to vibration or cable strain during operation.
• Wide Operating Temperature Range: Rated from -55°C to 105°C, ensuring stable performance in harsh thermal environments and industrial applications.
• Glass-Filled PBT Insulator: Offers high mechanical strength and excellent insulation resistance, enhancing durability during repeated mating cycles.
• Free-Hanging (In-Line) Mounting: Supports flexible cable assembly designs without requiring a PCB footprint, simplifying wiring harness integration.

Pin Configuration and Functions

• No pin definition: This is a receptacle housing for crimp contacts. Individual pin functions are determined by the user's specific wiring and the mating header pinout.

Typical Applications

• Industrial Control Panels: Internal wiring for PLCs, sensors, and actuator connections requiring secure, vibration-resistant interconnects.
• Office Automation Equipment: Power and signal distribution in printers, copiers, and multifunction devices with limited internal space.
• Consumer Electronics: Cable-to-board interfaces for home appliances, gaming consoles, and audio-visual equipment.
• Medical Diagnostic Devices: Reliable internal cabling for patient monitoring systems and portable diagnostic tools.

Equivalent / Alternative Parts

• DF51K-24DS-2C (Hirose): Base product number; identical specifications and form factor for direct replacement.
• DF51A-24DS-2C (Hirose): Alternative series variant with similar 2.00mm pitch and locking ramp, but verify keying and polarization differences.

Design-in Tips

• Use Specified Crimp Contacts: Always pair this housing with Hirose DF51 series crimp terminals (e.g., DF51-2428SCF) to ensure proper retention force and electrical contact.
• Verify Mating Header: Ensure the mating pin header has a corresponding locking ramp feature and 2.00mm pitch to achieve full mechanical latching.
• Handle with Care During Assembly: Avoid excessive force when inserting contacts; use a dedicated crimp tool to prevent damage to the housing latch or terminal retention tines.
