JST GH Connectors 1.25 mm Pitch

GH 1.25 mm Pitch Connectors

  • The GH 1.25 mm Pitch connector is a low profile connector designed for Plasma Display Panels (PDP’s), Liquid Crystal Displays (LCD’s) or other small sized equipment.
  • Like the SH series, the GH 1.0 mm pitch connectors are also heavily used in small racing drones.
  • Scondar offers a crimp style lock and a configuration which prevents users from inverted insertion.
  • Delivers up to a current rating of 1.0 A per contact for American Wire Gauge (AWG) #26, #27, #28, #29, #30
  • Suitable for either power transmission systems or chassis wiring.

Offers Design Flexibility in a Variety of Configurations to Choose From

Engineered to be space efficient which provides significant PCB savings, Scondar manufactures different models, in different dimensions, with top or side entry configurations.

Top entry configuration only consumes a height of 7.3 mm and depth of 4.25 mm. Whereas, Side entry configuration consumes a height of 7.15 mm and a depth of 4.35 mm.

Variation in Number of Circuits

In addition to the above flexibility in configurations of the JST GH 1.25 mm pitch connector, Scondar also offers this connector with different number of circuits ranging from 2 to 20 circuits which would suit your specific need.

Durable Product Design and Secure Locking Structure

No alloy was used in fastening the wires to the board, but through the use a crimping method, which makes it more flexible and mechanically stronger. The crimps are well engineered to be air-tight, preventing oxygen and moisture from reaching the metals, causing corrosion. Thus, the connector can be easily removed from the head without holding the wires. Furthermore, it prevents the cables from being easily disconnected due to entangled routing or heavy loads.

Compatibility with SHL Connectors

The JST GH 1.25 mm connector has compatible features with SHL connector, so in the absence of an SHL connector, the GH 1.25mm can be utilized as a replacement.

Optimized Safety Feature for Electrical Shock Hazard

With its improved product enhancement, the connector has the capability of withstanding voltage of 500V AC per minute, which means to say that the insulation is sufficient to protect the user from electrical shock, overheating and fire.

Material and Finish

The header contact is made up of copper alloy, tin plated over a phosphor bronze material. The housing is made of PA UL94V-O natural ivory. These housings are available with or without protrusions.

The solder tab is made up of brass, copper undercoated or tin-plated.

Temperature range, insulation and contact resistance

The temperature range for the 1.0 mm connector is -25 degrees centigrade to +85 degrees centigrade. This range is based on the rise of temperature with increasing current.

Insulation resistance and contact resistance are of 100 Megaohms per minute minimum and 50 mega ohms maximum, respectively.

Applicable in Chassis Wiring and Power Transmission Wiring

The 1.0mm Pitch Connector can be used for AC and DC operations with a rated current of 1.0 amperes and 50 Volts. It is applicable in both chassis wiring and power transmission wiring with a maximum amperage of 1.0Amp and 0.2 Amp, respectively.

Fine wires are usable

The connector can be used with the wires of AWG within the range of #26 to #30. This applies to wire diameters 0.2mm to 0.4mm.

Shrouded Header

The pin header of the connector is wrapped with a thin plastic guide box around it good for preventing cable connection mishaps and it also provides good guidance for the mating connector.

Twin U-slot section

Twin U-slot section or twinaxial cable has a pair of insulated conductors where the conductors are run parallel with one another. This is commonly used in high-speed balanced-mode multiplexed transmission in large computer systems, in which the signals are carried by both conductors in a U-shaped configuration. This ensures reliable connection and provides greater noise immunity.

Item Packaging

The housing and wafer package are available as 1000 Pcs per bag.

For terminal purpose the available package offers 20,000 Pcs per bag.

For wire harness, you can ask for custom materials with 1000 Pcs/bag.

Fits Microelectronics Systems

1.0 mm pitch serves as the best choice for densely crowded electronics systems for its small, square-edged configuration, ruggedized and shock resistant feature.

Caters Power, Signal and Grounding Contact Needs

The 1.0 mm Pitch connector can either stand as power contacts, signal contacts or both as power and signal contacts or a signal and grounding contact. The wiring harness interconnects the PCB to various components that sends signals and power to other electronic devices.

Safe and Reliable

SH 1.0mm pitch connectors ensures safety, system protection and performance with its bonded metallic conduits and multiple grounding points preventing fire hazards, component damage, overheating and possible electrocution.

The product does not contain restricted chemicals in concentrations not complying with ROHS standards. Thus, for its components, the products can be worked upon at high temperatures required by lead-free soldering.

Widely used in Electronic Equipment

It can be used in all types of PCB assemblies, projector, and high power applications, computers, inkjet, notebook PC, ATM machines, LCD, security systems, digital camera, cell phones, scanner, medical equipment, fingerprint machines, taximeter, automobile, power source for communication devices and many more.

Testing Equipment

Testing equipment are often used for quality control of products, experimentation and R&D. Scondar provides GH 1.25 mm pitch connectors for the following testing equipment:

  • -multimeters
  • -ohmmeter
  • -voltmeter
  • -laboratory testing equipment

Automotive Industry

Driving requires not only the physical coordination of your hands and thought, but also high-quality automotive parts which are fine-tuned and in good condition. The combination switch is one thing because it allows you to turn the headlights on and off, maneuver the headlight beam function and turn signal lights on.

Scondar offers JST GH 1.25mm pitch wire to board connector used in the combination switch and other automotive components such as the following:

  • -shifters
  • -steering
  • -instrument panels
