Nano-Fit Wire to Board power connector crimp housings with a 2.5 mm pitch designed to provide full contact isolation. The compact package and tight pitch of these receptacles combined with optimum current density offer increased design flexibility for engineers in a wide range of applications. These Nano-Fit crimp housings are designed to provide full electrical isolation between the crimp terminals and to prevent arcing. Full isolation also prevents damage to the contacts during handling and mating and reduces the risk of shorting due to debris. These Nano-Fit crimp housings feature positive locking latches with an anti-snag design which prevents accidental disengagement and protects against damage caused by wire snags. The positive locking feature of these Nano-Fit power connector housings also prevents accidental mismating caused by shock, vibration or excessive cable strain. An audible click is produced to confirm mating completion. Tactile feedback is also provided when mis-mating is attempted. Polarization and keying aid accurate mating and prevent misalignment therefore reducing the errors that can be caused due to improper installation.
These Nano-Fit crimp housings are designed to be used with TPA (Terminal Position Assurance) retainerswhich are available separately (see stock number 122-4858 typically)
Crimp receptacles must be purchased separately (see stock numbers 122-4835 and 122-4836)

This connector housing offers robust performance for various electrical applications. Made from durable nylon, it provides a solid solution for securely connecting multiple circuits, essential for scenarios where stable connections are important, especially in automation, electronics, and mechanical sectors.

• Compatible with 4-pin female crimp terminals for flexible connections
• Designed for cable mount, facilitating simple installation
• Features a 2.5mm pitch for effective spacing between connectors
• Straight body orientation optimises space in compact assemblies
• TPA retainer compatibility increases connection reliability

• Used in power requiring secure wire-to-board connections
• Suitable for wire-to-wire in automated systems
• Ideal for devices requiring low-hazard levels due to glow-wire capability
• Functions effectively with Nano-Fit receptacles for improved connection integrity

While specifically designed for Nano-Fit terminals, it may be compatible with other products in the series.

Using 20AWG wire is advisable for optimal performance when crimping inside the housing.

An extraction tool for crimp terminals is recommended for proper installation and maintenance.

The TPA retainer secures the terminals, minimising the risk of accidental disconnection.
