GDM2009-GY Rectangular Connectors for Electronic Projects

Overview

The GDM2009-GY rectangular connector family provides a space-efficient mating interface used in hobby, education and light-industrial electronics. These connectors are commonly used for board-to-board, cable-to-board and panel installations where a keyed rectangular housing and multiple contacts simplify wiring and servicing. In South African workshops and labs, the GDM2009-GY is useful for small control panels, sensor harnesses and modular prototyping racks.

Typical applications

• Microcontroller I/O breakout connections and detachable sensor modules
• Panel-mounted sockets for quick swap of instrument modules
• Power and signal harnesses in robotics and educational kits

Key mechanical and electrical points

When evaluating the GDM2009-GY, check these attributes: contact count and pitch, rated current per contact, housing material and keying, mating cycles, and termination style (through-hole, surface-mount or crimp). For many maker projects, pitch and contact type drive compatibility with PCB footprints and crimp housings.

Selection checklist

• Confirm contact count and pitch to match your PCB footprint.
• Decide termination style (solder tail vs. crimp) based on assembly method.
• Verify rated current and contact plating for your power/signals.
• Consider keyed housings or latch features for retention and polarity protection.

Compatibility & Installation Guidance

Match the connector pitch and footprint exactly when designing PCBs. If you plan to use crimp contacts, select crimps and crimps tools rated for the conductor gauge (commonly 26-20 AWG for small rectangular connectors). For panel installations, check whether the mating plug includes a hood or latch and allow mechanical clearance in enclosures.

Wiring & basic calculations

Estimate conductor size from max current per contact. A quick reference: at ambient room temperatures, a 1.5 A continuous current is typically safe on 26 AWG, while 3-5 A is commonly supported on 22-20 AWG depending on connector rating. These are estimates - always check the specific connector datasheet for exact ampacity and derating at temperature.

Ohm's law (for voltage drop and power dissipation):
V = I * R
P = I^2 * R
Example: 2 A through a contact with 0.05 ohm resistance -> Vdrop = 0.1 V, P = 0.2 W

Accessory bundles and compatibility tips

• Crimp contact sets that match the housing series (verify series code).
• Latching housings and mating plugs for vibration-prone projects (robots, mobile platforms).
• Heatshrink tubing or cable management clips for strain relief on cable assemblies.
• Matching PCB headers (through-hole or SMT) and right-angle options where space is constrained.

Specification callouts & comparison

Ordering & support (South Africa)

When ordering, specify: housing part number, contact type and plating, pin count, pitch, termination and quantity. Communica can provide VAT invoices and quotes for procurement teams and education projects. If you need assembly-ready harnesses, ask about crimped cable assembly lead times - pricing in ZAR will depend on quantity and custom work. For small runs, stock items and matching crimp kits keep turnaround short; specialised mouldings may have longer lead times (estimates vary).

• Check stock availability on the Samrand branch page before planning urgent builds.
• Request a quote for larger volumes - pricing in ZAR (estimates provided on request).
• Collect at branch or arrange courier delivery nationwide.
