Multi-Pin KTK
Rugged multi-pin hermetic connectors built with PEEK insulation for reliable electrical performance under high pressure, high temperature, shock and vibration.
Industry interchangeability with a more rugged insulator.
Rampart Products’ KTK connectors interchange with industry standards while replacing traditional glass-reinforced epoxy insulation with a rugged PEEK body. The result is a durable multi-pin connector designed for demanding HPHT electrical applications.
Built for reliability in severe service.
The KTK platform combines beryllium copper contacts, a copper-alloy support disk and a PEEK connector body in configurations designed for high-pressure, high-temperature environments.
HPHT and MPMT versions provide different pressure and temperature capabilities while retaining the same rugged connector architecture.
More durable by design.
KTK combines industry-standard compatibility with details engineered to simplify assembly and improve performance in demanding mechanical environments.
Designed for seamless integration with established industry-standard interfaces.
Tiered solder-cup geometry provides easier access during wire termination and assembly.
High contact force supports reliable electrical connection under shock and vibration.
PEEK body construction is twice as durable as glass-reinforced epoxy according to the catalog specification.
Standard KTK configurations are maintained in stock for responsive delivery requirements.
