ITT Cannon DL Series Thermoplastic Right Angle D-Sub Backshell, 156 Way Strain Relief 249-1950-000

The ITT Cannon DL Series Thermoplastic Right Angle D-Sub Backshell, model 249-1950-000, is engineered specifically for high-density multi-pole connector assemblies requiring reliable strain relief and rugged performance in demanding environments. With a 156-way configuration, this backshell is ideal for applications in diagnostic and test equipment, instrumentation, medical devices, computers, audio systems, broadcast equipment, and avionics systems.

This product utilizes a thermoplastic housing, chosen for its cost-effective nature and durability. The fibreglass reinforced thermoplastic plating provides increased mechanical strength and resilience, making it suitable for installations subjected to frequent handling and mechanical stress. The backshell kit is supplied with a cable strain relief clamp, ensuring secure retention of cable assemblies and offering flexibility between straight or right angle cable entry as required by the installation. Strain relief is a key feature that helps protect cable terminations, preventing accidental disconnection and minimizing wear during repeated mating cycles.

The 249-1950-000 model is part of the DL range from ITT Cannon, which is renowned for its zero insertion force (ZIF) technology, ensuring easy coupling and uncoupling of connectors while preserving contact integrity and supporting up to 10,000 mating cycles. Its high pin count enables complex electrical connections within compact spaces, supporting modern instrumentation and communication protocols. Both plug and socket bodies are compatible, offering flexibility in design layouts, while backshell and polarization options allow for tailored setups and orientation-specific installations.

Plastic hoods, such as this thermoplastic variant, are preferred for their cost efficiency in systems where electromagnetic shielding is not critical. For environments where EMI shielding is necessary, nickel plated aluminium die-cast metal backshells are also available in the DL range. This product’s robust construction, high-density contact support, and versatile strain relief make it an excellent choice for industrial, laboratory, and commercial electronic applications.

Common industrial use cases include laboratory electronics, automated test equipment, medical diagnostic instruments, industrial automation controllers, aerospace monitoring devices, high-density computer interface modules, and broadcast signal distribution systems.
