Headers are completely polarized and shrouded (for the radial type). This connector delivers about 3.0A AC/DC current with 2 through 16 positions, accepting a range of 22 AWG to 28 AWG.

Dupont 2.5 Pitch Connector

Dupont 2.5 mm Pitch connector is a low profile connector delivering 3.0A current for AWG #22 to #28, available in 2 to 16 positions suitable for either power transmission systems or chassis wiring. Scondar offers a crimp style lock and a configuration which prevents users from inverted insertion.

Dupont 2.5 connector is has a flexible terminal strip and board stackers for stacking. It is available as either with a shrouded or unshrouded header, with configurations for through-hole, SMT or mixed technology and press fit. It is also available for either vertical, perpendicular or coplanar mating and offered in a wide variety of standard options such as polarization, locking clips and alignment pins.

JAE IL-G Connector

The 2.5 mm JST IL-G connector series is a compact component delivering dependable service in requirements for high density connection to printed circuit boards. It is specifically designed for harsh environments which are frequently subjected to heat and vibration such as in heavy equipment vehicles and batteries.

Delivering up to a current rating of 3.0 A and 250 V, it is applicable for AWG 22-28. It is enclosed in crimp-style lock and a completely polarized configuration which prevents users from inverted insertion and is available in 2 to 16 positions.

Molex SPOX Connector

Scondar’s Molex SPOX of wire-to-board and wire-to-wire connectors is a reliable, compact and durable connector for power delivery and power distribution requiring a huge amount of flexibility.“SPOX” is a name which originates from the shape of its terminal that is like a spring box, which provides multiple points of contact and protects the mating interface area, preventing fish-hooking and wire mishaps.

The 2.5 mm pitch SPOX is available in 2-16 positions, dissipating 2A for AWG #22 – #30 and has a box-style terminal, polarized design, friction locks, kinked tail options and crimp and IDT housings, meeting a variety of design needs.

Components of 2.5 mm Connectors

Housing

The connector housing provides electrical insulation between the contacts and between the contact and the external circuit. Dielectric Withstand Voltage (DWV) usually verifies the voltage rating of the connector.

A well-designed housing holds the connector contacts providing trouble-free mating and unmating. Spacing between the contacts is also fixed by the housing. Creep (electrical tracking distance over surfaces) and clearance (linear “line‐of‐sight” distance) is also maintained by the housing.

The housing is smartly engineered to allow efficient signal and power transmissions and at the same time, provide some level of environmental protection to the electrical contacts.

Scondar manufactures the housing from Nylon 66, which is a material highly used when high mechanical strength, rigidity, stability is needed under varying temperature changes. That is why all Scondar connectors can withstand a wide temperature range from between -35 deg C to 85 deg C.

Furthermore, the housing is molded in UL94V0 natural ivory and is RoHS compliant, which has passed the flammability test for electronics and as such, the connectors produced by Scondar are ideal in rugged electronic devices, sustaining high environmental stresses. Also, the housing may be available with or without protrusions, depending on customer needs and specifications.

Header

The header contact is made up of copper alloy, tin plated over a phosphor bronze material.

Terminal

Scondar’s connector terminals are made of tin-plated, phosphor bronze. The terminals have a thickness range of 0.12mm-0.15mm depending on the 2.5 mm connector type and standard reels are 20,000 pieces per reel.

Tin-Plating

Tin-plating is less costly and generally for applications carrying more than 0.5A, where high cycling is specified.

Phosphor bronze

Phosphor bronze is stronger than brass and has better spring properties that lends itself useful in smaller contacts that can best leverage its mechanical properties. This material is commonly found in small and medium‐pitch signal and moderate‐power connectors.

Quality Assurance of Components

How Scondar makes 100% Reliable and Compatible Connectors

Quality is at the heart of Scondar’s standards where facilities are UL & ISO 9001:2008 certified. Scondar ensures materials and components always meet their needs with UL file number and ISO certification.

Assemblies are 100% tested guaranteeing reliability and compliance, a variety of appropriate tests are applied depending on cable assembly type. Examples are: Short or open circuit, intermittent circuit, mis–wiring. Hi-Pot, static load for strain relief, bending test, crimp pull off force, contact to housing retention force and plastic hardness.

Individual discrete wires are stripped of insulation, crimped and then inserted into female housing to complete the assembly. The completed assembly mates with a male PCB header, which offers options for locking, latching and polarised connectors.

Wiring Harness/Cable Assembly

In many cases, a wire harness or cable assembly is needed to compress masses of wires stretching over a distance. By binding these wires into cable assemblies, these cables can be better secured against the adverse effects of vibrations, abrasions, and moisture.

Scondar’s wires are produced into a non-flexing bundle, for space optimization and safety purposes, where installation time can be decreased and the process of installing electronic circuits in standardized. Their positive locking latch provides only a slight increase in disengagement force of the terminals.

Blind-mating solutions implemented in the connectors allow engagement of the connector system without visual alignment. Scondar connector series has a heavy-duty, shrouded design providing positive polarization to aid in blind mating applications. Scondar meets close adherence to the connector system specifications for blind-mating solutions for a more efficient connecting system and interference capability.
