Plug (Self-Locking) • TC09
Self-locking plug for high reliability
This plug features a self-locking coupling ring designed for applications subjected to high vibration, or when an extra level of protection is required. The self-locking clutch provides tactile and audible confirmation of coupling. Covers are recommended to protect contacts and coupling threads.
Wall Mount Receptacle • TC00
Flanged receptacle for easy panel mounting
The wall mount receptacle features a four hole flange for easy installation. This receptacle may be front and rear mounted for application flexibility. A gasket and mounting bracket with sealing screws are recommended for environmental installs.
Box Mount Receptacle • TC02
Low-profile receptacle for confined spaces
The box mount receptacle has a standard four hole flange for front or rear panel mounting. The low-profile rear design does not permit the use of backshells. Protective covers and a gasket are recommended to protect contacts and seal the mounting location.
Jam Nut Receptacle • TC07
Jam nut receptacle with integrated O-ring
A jam nut receptacle offers increased environmental protection due to a single hole mounting design. An integrated silicone O-ring seals the mounting location to maintain environmental integrity. Covers are recommended to protect contacts.
Cable Mount Receptacle • TC01
Receptacles for extension cord applications
This receptacle features a reduced flange to protect coupling threads from impact when dropped or dragged. A strain relief backshell is required to protect terminations from cable tension. Covers are recommended to protect the contacts and coupling threads when the receptacle is not in use.
Thru-Bulkhead Receptacle • TC22
Dual receptacle ends for bulkhead feed-thru
This special connector has receptacles on both sides of the shell in order to connect cable plugs from both sides. One side of the shell features socket contacts, the other side pin contacts. A mounting bracket and gasket are recommended.
Straight Strain Relief Backshell • TCB2
Protect connectors from cable strain
Provides strain relief protection required by all cable plugs or cable connecting receptacles. Use self-locking design for high-vibration environments. Upgrade to an environmental backshells for outdoor or harsh environment applications.
90° Strain Relief Backshell • TCB4
Strain relief and cable management
Angled strain relief is useful in environments where space is limited and cable management is required. The self-locking design is recommended for high-vibration environments where added protection is required.
Straight Environmental Backshell • TCE2
Strain relief & Environmental protection
Environmental backshells feature glands that seal both entry points, providing IP67 environmental protection from water, moisture, dirt, and dust. A cable clamp on the back of the shell provides necessary strain relief. Upgrade to EMI/RFI environmental backshells for shielded applications.
45° Environmental Backshell • TCE3
Provide accessibility with angled backshells
Angled environmental backshells are perfect for applications that require cable management and IP67 protection. Glands seal against the cable jacket and keep out dirt, dust, water, and moisture, ensuring complete reliability. Upgrade to an EMI/RFI environmental backshell for shielded applications.
90° Environmental Backshell • TCE4
Cable management and IP67 protection
This backshell features a 90° angle that provides excellent cable management in confined spaces. IP67 environmental protection is provided by glands that seal against the cable jacket and keep out dirt, dust, water, and moisture. A strain relief clamp protects contacts from cable tension.
Straight EMI/RFI Environmental Backshell • TCR2
Ultimate environmental & EMI/RFI protection
These backshells provide strain relief from cable tension, environmental sealing rated to IP67, and feature 360° shield termination hardware. They provide complete EMI/RFI and environmental protection for all mission-critical designs.
45° EMI/RFI Environmental Backshell • TCR3
Simple cable management, full protection
These backshells provide strain relief from cable tension, environmental sealing rated to IP67, and feature 360° shield termination hardware. The 45° angled design provides cable management in confined spaces or high-density panels.
90° EMI/RFI Environmental Backshell • TCR4
Full protection and easy cable management
This 90° backshell provides cable management in tight spaces. Glands seal against the cable jacket, providing IP67 environmental protection, while a cable clamp offers relief from cable strain, and internal hardware offers complete 360° shield termination for EMI/RFI protection.
Straight Shrink Boot • TCK2
Environmental protection, low-profile design
A shrink boot provides complete IP67 environmental protection and strain relief. Must be used with a boot adapter.
90° Shrink Boot • TCK4
Angled boot for simple cable management
90° shrink boot provides complete IP67 environmental protection and strain relief in a low-profile backshell design. A boot adapter must be used for proper installation.
Boot Adapter • TCAB
Adapter for shrink boot installation
This adapter is specifically designed to provide shrink boots with a groved platform for superior grip and environmental sealing. The design allows for unscrewing of the connector for field inspection without removing the shrink boot.
EMI/RFI Banding Boot Adapter • TCD2
EMI/RFI shield termination with shrink boots
The EMI/RFI banding boot adapter provides effective shield termination for applications using a shrink boot. Shielding is achieved with a band applied by a simple hand tool over a specially designed platform. The overlaying boot ensures strain relief and complete IP67 environmental protection. Each adapter is supplied with a shield termination band.
Protective Covers • TCCP/TCCR
Protect uncoupled connectors from harm
Connectors should always be paired with protective covers to environmentally seal and protect the connector from damage. In addition to protecting contacts, covers also protect the coupling threads from impact and debris, ensuring reliable coupling.
Stowage Receptacle • TCCD
Store and safely isolate unmated cables
Prevent operator injury and connector damage by providing a safe place to safely stow and organize unused cables. Solid flange (TCCC) stowage receptacles are available when full environmental sealing is required. Covers are also recommended to keep unused stowage receptacles clean and dry.
Mounting Gasket • TCGE
Seal out environmental hazards
Mounting gaskets will seal the mounting space between the receptacles and the panel to maintain the environmental integrity of your enclosure. They may be used in either rear or front mount receptacle installations.
Mounting Bracket & Screws • TCMB
Ensure reliable mounting
Mounting brackets with captive stainless steel locking nuts prevent loose fasteners from falling into susceptible areas, which may cause equipment failure. Optional sealing screws with O-rings will effectively seal the mounting holes on your enclosure from water ingress.
TC Series Contacts & Sealing Plugs
High-performance crimp contacts
TC Series contacts are machined from copper alloy and are gold plated for the highest electrical continuity and corrosion resistance. The series offers contacts in sizes #0, #4, #8, #12, and #16, which are suitable for 0-20 AWG wire and are rated for up to 150 amps. In addition, thermocouples are available in sizes #16 and #20. Sealing plugs are required for any open positions in a connector to maintain reliable environmental protection.
TC Series Crimp Tool • TK101
Hand crimper for all #12 and #16 TC Series contacts
The TK101A precision crimp tool enables termination of contacts from #12 to #20. The tool features an eight impression crimp, which ensures maximum tensile strength between wire and contact. The cycle controlled ratchet is consistent and accurate and does not permit half crimps, ensuring complete and precise crimping every time. For larger TC Series contacts (#0, #4, #8), the TU103A pneumatic crimper must be used.
TC Series Contact Insertion & Removal Tools
Reliable contact insertion and removal tools
We ship plastic contact insertion and removal tools with every crimp connector. And while they offer a convenient solution for connector repair in the field, some applications demand more durable and precise tooling. Our stainless steel contact insertion and removal tools are the best option for production environments where higher tool reliability is required.
