JST GH1.25mm Assorted Connector Kit 2-5 Pin Horizontal Housing 60PCS with Crimp Pins

Specifications 

• Connector Type: JST GH1.25mm pitch, horizontal, crimp-style wire-to-board, disconnectable
• Kit Contents: 60 pieces total (2P/3P/4P/5P male headers, matching female shells, crimp terminals)
• Pitch: 1.25mm
• Voltage Rating: Not specified by manufacturer sources 
• Operating Temperature: -5°C to +45°C 
• Housing Color: White
• Contact Material: Brass
• Locking Mechanism: Locking buckle  requires deliberate force to disconnect, preventing unwanted separation
• Compliance: RoHS compliant
• Packaging: 10-compartment clear plastic storage box

Minimum hardware

• GH1.25-specific crimping tool  a distinct die size from SH1.0, ZH1.5, PH2.0, and XH2.54; none of the other tools in this session's lineup will work correctly here
• Fine-gauge wire (28-30 AWG typical)  matched to Pixhawk-ecosystem wiring conventions
• Magnifying tool or loupe  recommended given the fine pitch, similar to the ZH1.5 and SH1.0 kits

Safety Warnings

• Crimp Tool Warning: Do NOT use a tool sized for SH1.0, ZH1.5, PH2.0, or XH2.54 on these GH1.25 terminals  each JST family in this session's lineup requires its own dedicated die
• Wire Gauge Warning: Wire outside the 28-30 AWG range typically won't seat correctly in the GH1.25 crimp barrel
• Flight-Critical Wiring Note: GPS and telemetry connections are often flight-critical  double-check every crimped connection with a multimeter before final assembly, since a bad connection here can mean lost GPS lock or telemetry mid-flight

Accessories Included in the Box

• 2/3/4/5-Pin Male Headers (white housing, horizontal mount)
• Matching 2/3/4/5-Pin Female Shells with locking buckle
• Loose Crimp Terminals
• 1× 10-Compartment Plastic Storage Box

Frequently Asked Questions

• Are these terminals compatible with standard JST GH connectors from other brands?
  Yes, GH1.25mm is a standard pitch and housing shape, compatible with genuine JST GH connectors and compatible clones.
• Will this work with my Pixhawk 2, PIX4, or Pixracer flight controller?
  Yes, GH1.25mm is the standard connector across most Pixhawk-family boards including Pixhawk 2 (the Cube), PIX4, Pixhack, and Pixracer.
• Is this the same as the SH1.0mm or ZH1.5mm kits sold separately?
  No, GH1.25mm sits between SH1.0 and ZH1.5 in size  all three require their own dedicated crimping tool and are not interchangeable.
• Can I use this for GPS module connections?
  Yes, this is one of the most common uses for GH1.25 connectors on Pixhawk-family boards.
• What's the maximum current these terminals can safely carry?
  Rated at 1A per confirmed component specifications  suitable for low-current peripheral connections like GPS and telemetry, not high-power applications.
• What's the voltage rating for this connector series?
  A specific voltage figure wasn't published by available manufacturer sources  treat this as a low-voltage signal/peripheral connector consistent with its 1A current rating, and avoid using it for anything beyond typical flight-controller peripheral voltages.
• Is this suitable for a Pixhawk power module connection?
  Power modules typically draw more current than this connector's 1A rating supports  verify your specific power module's current draw before using GH1.25 for that connection; it's better suited to GPS, telemetry, and similar low-current peripherals.
• How fine does my wire need to be for these terminals?
  Typically 28-30 AWG  check your wire's actual gauge before attempting a crimp.
• Can I use a SH1.0 or ZH1.5 crimping tool on these GH1.25 terminals?
  No, each JST pitch in this session's lineup requires its own dedicated crimp die  using the wrong tool will damage the terminal.
• Does pin order matter when assembling a connector?
  Yes, always match your pin order to your flight controller's documented pinout  reversing pins on a GPS or telemetry connection can cause the module to malfunction.
• Why won't my crimped terminal stay locked in the housing?
  This usually means the crimp terminal's locking tab is bent or damaged during crimping  inspect carefully before insertion.
• Why is my connection intermittent after crimping?
  A poor crimp is the most common cause  retest with a proper GH1.25 crimping tool and appropriately fine wire gauge.
• The male and female housings don't seem to click together  what's wrong?
  Confirm both housings are genuinely GH1.25-series and the same pin count before assuming a defect  the locking buckle needs full engagement to click.
• Can a bad crimp cause my GPS to lose lock intermittently?
  Yes, a loose or poorly seated crimp on a GPS connection is a real cause of intermittent signal issues recheck and recrimp if you're seeing inconsistent GPS performance.
