Cut-to-fit connector, 10037494, FISCHER EL

The KK 40 Z is a high-quality printed circuit connector designed with a 2.54 mm pitch and a design DIL format, featuring 40 poles arranged in two rows. Its robust construction includes a CuSn-alloy contact material with a Ni + 5...10 µm Sn-plated contact surface, ensuring reliable electrical connections. The connector supports THT soldering and accommodates ribbon cables with an excess length to the case of at least 1 mm. It meets stringent safety and performance standards, including a nominal voltage rating of 250 V AC (insulation group A, VDE 0110), a test voltage of 500 V AC, and a creepage distance ≥ 0.7 mm and clearance distance ≥ 0.5 mm, complying with VDE 0110 requirements. The insulating body, colored RAL 7032, withstands temperatures from -55°C to +125°C and meets the UL 94 V-0 flammability class, with a specific insulation resistance exceeding 10¹² Ω·m.

This connector is ideal for applications requiring secure and durable connections in industrial and electronic manufacturing environments. Its compatibility with AWG 28 to 30 conductors (0.09 to 0.05 mm² cross-section) and support for both solid and stranded ribbon cables make it versatile for various wiring needs. The IDC pattern of 1.27 mm further enhances its adaptability in complex circuit designs, ensuring efficient signal transmission and mechanical stability in printed circuit board assemblies and related electronic systems.
