The CE100F28-04-D_E is a female connector end for the Series 100 MAS-CON modular connector system with 2.54 mm pitch spacing. It accommodates 28 AWG wire with a contact cross-section of 0.2 mm and is color-coded green for identification. The connector is rated for a current of 3.0 A at 300 V AC, with a maximum contact resistance of 10 mO and a withstand voltage of 750 V AC/DC per minute. The insulation resistance is specified at 1000 MO minimum, and the connector operates reliably across a temperature range of -55 °C to +105 °C. The contacts are made from copper alloy with tin-nickel plating (gold plating available upon request), and the insulator material is PA66 UL94 V-2 flame-retardant plastic. This connector is commonly used in industrial control systems, telecommunications equipment, and low-voltage power distribution applications where reliable, compact connections are required.
