A friction lock housing enables secure connections. This series delivers a current rating of 2A, 250 VAC/VDC for a maximum PCB thickness of 1.6mm and for wire gauge AWG #24 to AWG #30.
Components of 2.0 mm Pitch Connectors
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 -25 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.
The header contact is made up of copper alloy, tin plated over a phosphor bronze material.
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 2.0mm connector type and standard reels are 20,000 pieces per reel.
Tin-plating is less costly and generally for applications carrying more than 0.5A, where high cycling is specified.
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.
For 2.0mm connectors, wire gauges that can be accommodated with the rated current and voltage is between AWG #22-30. The following table represents the specs of these wire gauges.
