The modular connectors on the Flat 6 core cables shall be 6 position 6 contact (6P6C) with the pin-out configuration being as follows:

1-1, 2-2, 3-3, 4-4, 5-5, 6-6

The physical dimensions of the male and female connectors shall be as per ANSI/TIA-1096-A and ISO-8877 standards. Typically the contact spacing is always 1.02 mm (centre to centre)

Contacts on 6P6C Modular connector plug and jack contactsImage Added

1️⃣ JST VA Connector: The JST VA Connector is active, neutral and earth. The connector on the transformer is female and it connects into the male connector on the C225 module

2️⃣ Transformer: The transformer provides 24V power to the C225 module and is used to power all the zone dampers, connected modules and touch screens

3️⃣ 240 VAC lead: The 240V lead consists of active, neutral and earth conductors

4️⃣ AU Plug: Standard 3 Pin AU plug

1️⃣ The material content shall be 99% pure gold minimum

2️⃣ The material density shall be 17 grams/cm3 minimum

3️⃣ The minimum gold thickness in the specified interface area shall be 1.2700 μm (50 μin)

4️⃣ The Knoop micro-indention hardness value shall be between 130 and 250 when measured in accordance with ASTM E384-05a using a load force of 0.245 N (25 g)

5️⃣ EMC ferrite

6️⃣ 24V lead: The 24V lead consists of active, neutral and earth conductors

• A nickel barrier layer shall be used between the gold surface layer and the base metal. It shall meet the following requirements:

1️⃣ The material content shall be 99.5% pure nickel minimum, and no other single component shall be more than 0.2%

2️⃣ The minimum nickel thickness shall be 1.2700 μm (50 μin)

3️⃣ The nickel barrier layer shall not crack when a contact sample is bent through a 180° angle, with the plated surface away, around a mandrel whose diameter is equal to the thickness or diameter of the contact sample

1️⃣ The plug/jack contact interface shall be hard gold to hard gold and shall have a minimum gold thickness of 1.2700 μm (50 μin) on each side of the interface. Alternative contact material that is compatible with hard gold and provides equivalent contact performance may be used under certain conditions. The minimum contact force at the interface shall be 0.98 N (100 g). A smooth, burr-free surface shall exist at the interface in the area shown. Contact surface roughness shall be 0.8128 μm (32 μin) maximum. Compliance can be determined by observation with 10X magnification. Compare surface protrusions and burrs on the contact surface with a 32-μin, ground-surface-finish gauge.

2️⃣ The jack contact design is based upon 0.4572 mm (0.018 in) spring temper phosphor bronze round wire in the modular plug blade and jack contact interface. Other contact configurations that provide contact performance equal to or better than the preferred configurations and do not cause damage to the plug or jack are permitted. Contact width should be 0.44958/0.49530 mm (0.0177/0.0195 in). Deviations from the desirable jack contact width are permitted for round contacts as well as noncircular cross sectional shapes but they shall be compatible with existing plug configurations.
