Overview
The Raychem TXR41AB00-1812AI is a circular connector backshell engineered for reliable cable entry and strain relief in demanding industrial and military environments. As a TINEL-LOCK termination adapter, it delivers repeatable, secure overbraid connections using heat-activated ring termination technology.
Key Features
- TINEL-LOCK ring termination—braid is terminated using a resistance heater for consistent, reliable connections
- Size 18 adapter rated for cable diameter range 12.7–20.3 mm
- Aluminum construction with bright anodize finish for corrosion resistance
- MIL-DTL-38999 Series III compliance ensures compatibility with standard circular connectors
- Operating temperature range –65 to 175°C supports extreme environment applications
- 500-hour salt spray resistance verifies durability in corrosive conditions
