PNI Connector

Wire-to-Board and Wire-to-Wire

Many applications require design flexibility in a connector system to incorporate both wire-to-board and wire-to-wire connections without switching to a different connector series allowing the user to use the same application tooling. The PNI series, crimp-style connectors are offered for wire-to-board and wire-to-wire applications on a 2mm (.079”) pitch, molded in a RoHS compliant 94V-0 through-hole headers and housings, and incorporate both polarization and a secure locking feature and is designed to prevent contact stubbing / back-out when mated. Rated 3A  AC/DC (using 22AWG) at 100V.  These robust connectors are available with a secondary retainer to ensure the contacts are fully seated and locked into the housings to prevent accidental release. The positive locking system is designed to fit inside the envelope of the header making it possible to stack the headers close together and still be able to release the positive lock.  The series has an operating temperature range of -25°C to +85°C including temperature rise when applying an electrical current. The series is offered in 2~10 circuit sizes.

The PNI Series is engineering and manufacturing friendly.

Applicators are available for semi-automatic and fully automatic termination equipment normally found in the manufacturing environment as well as standard hand tools and contact extraction tooling (insertion tooling is not required for the VL series contacts. Standard reels (2,000 pieces) for the VL series for semi-automatic and fully automatic assembly equipment are available for manufacturing.

PNI Connector crimp style receptacle & socket housings

Molded in Nylon 66 rated 94V-0 material, the polarized PNI series housings incorporate a secure locking device to prevent accidental disconnection due to routing of wires or vibration.  Available in 2 to10 circuits, the locking mechanism is designed for a secure and stable connection ideal for high vibration applications. An audible click is heard and felt when mating the plug housing assembly with the mating half. With the use of an optional secondary retainer, the contacts are fully seated and locked into the housings making it ideal for a high vibration environment. The wire-to-wire receptacle housings can be used in free-hanging (without panel locks) or panel mounted (with panel locks) applications.


Retainers are available for both the receptacle and plug housings.  While their use is optional, they provide additional contact retention security.  They are most often used in very high vibration applications.  As you can see from the above illustration, the retainer is slide into the contact cavities on the back side of the housing.  The fingers of the retainer rest behind the contacts, eliminating any change of contact backouts.  The retainers lock to protrusions on the sides of the housings.

Crimp Style Contacts

The PNI contacts, which are designed to accommodate a wire range of  wore sizes (28AWG to 22AWG) are tin-plated over a copper alloy base material. The suggested wire strip length for the wire is 2.2mm (0.87”).
