SEK IDC Connectors

Product catalog summary

Introduction
SEK IDC connectors are designed for flat cables, offering cost-effective and simple configurations for internal device connections. Suitable for both indoor and outdoor applications, including harsh environments, these connectors are assembled in one step for all contacts via flat conductors.

Specifications
The connectors support data and signal applications with a 2.54 mm pitch, available in solder or press-in terminations, and offer 6 to 64 pins. They meet IEC 60 603-13 standards, are UL recognized, and operate at 1 A and 500 V for pollution degree 1, with a test voltage of 1 kV. The temperature range is -55°C to +125°C.

Quality and Economy
HARTING ensures reliable connections through professional assembly and 100% quality checks, reducing the need for additional investments in workstations and test devices.

Technical Characteristics
Available in performance levels 2 and 3, with varying mating cycles and gas test requirements. Contact arrangements are straight and angled, with lengths of 2.9 mm and 4.5 mm. Made from thermoplastic resin (PBT) with plated contact surfaces.

Applications
SEK connectors are ideal for cable-to-PCB applications, providing durable gastight connections. Custom designs are available upon request.
