JST Connectors

1mm (.0394”) Pitch Connector

What is a 1mm (0.0394”) Pitch Connector

Generally speaking, a 1mm pitch connector is a small connector used in densely-packed or small-spaced PCB board.
Scondar offers the following 1mm pitch connectors with the same specs as the branded connectors such as JST SH.

JST SH Connector

The SH 1.0mm pitch connector is a low profile connector for small-sized devices which are commonly seen in small racing drones. In this connector design, a crimp style lock and a polarized design is incorporated in its configuration, securing the connector and preventing users from inverted insertion.

Engineered to be space efficient providing significant PCB savings, this connector has a minimum top entry height of 6.3mm and depth of 2.9mm and a side entry height of 2.95mm and depth of 6.35mm, delivering 1.0A AC/DC, and is available in 2 through 15 and 20 circuits, accepting a range of 28 AWG to 32 AWG. Furthermore, it is manufactured under high-pressure ensuring positive electrical contact and low contact resistance in the presence of strong vibration and distortion, making it suitable for both power transmission systems and chassis wiring.

JST NSH

This low-profile connector with polarized design and crimp-style is SMT compatible, rated at 1.0 A AC/DC, 50 volts and can accomodate 32-28 AWG. The contacts are tin-plated phosphor bronze providing reliability in signal transmission. Its components such as the housing and header are molded in a 94V- 0 PBT and is also ideal for rugged electronics devices, sustaining environmental stresses, complying with RoHS standards.

The series has an operating temperature range of -25 C to +85 C including temperature rise when applying an electrical current. It is offered in 2-15 circuit sizes. Furthermore, the series is supported with termination tooling.

JAE FI-E Connector

The JAE FI-E Connector is suitable for Low Voltage Differential Signaling (LVDS), operating at low power and at high speeds. This connector is an inexpensively made as it is very common in many data communication applications, industrial cameras and machine vision, notebook and tablet, computers and communications systems as high-speed graphics, video camera data transfers, and general purpose computer buses.

This connector is polarized and available in crimp-style, being compatible with SMT and available in 31,41 and 51 positions, with a current rating of 0.5A AC/DC, a rated voltage of 200V efficiently operating at -40 deg C to 80 deg C.

Hirose DF19 Series Connector

1 mm Contact Pitch, Board to Cable, Board to FPC, Board to Micro-coaxial Cable Connectors

Hirose DF19 series connector is a single-row, low profile connector available in 8, 14, 20, 30 positions, with either a straight or right-angle connector orientation and can accomodate wire sizes from 32 AWG to 28 AWG. The operating temperature ranges from -35C to 85 C, with a rated current of 1 A and rated voltage of 100 V.

This connector is made durable permitting mating alignment, a mechanical lock being available to prevent insufficient mating. Its low profile design has a height of 1.5 mm and depth of 7.2 mm for its horizontal configuration and a height of 1.7 mm and a depth of 7.2 mm for its vertical configuration. A crimp-style and solder-style is available for harnessing.

The same receptacle will accept plugs terminated with discrete wire, FPC or micro-coaxial cable. Wire termination method can be by soldering, crimping or FPC termination. This connector is also durably made, withstanding 30 repeated connection/disconnection while still meeting the specifications for maximum resistance.

Components of 1mm 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 1.0mm 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.

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.

Wire Gauge

For 1.0mm connectors, wire gauges that can be accommodated with the rated current and voltage is between AWG #28-32. The following table represents the specs of these wire gauges
