301A512-125-0 Description

Short technical summary and product information.

This TE Connectivity 301A512-125-0 is a heat shrink boot designed as a transition-breakout with a 2:1 (T) ratio. It is molded from black fluoropolymer material, offering excellent chemical and thermal resistance. The boot has a shell size of 12 and is intended for use in cable management applications where a transition from a larger diameter to a smaller diameter is required, along with a breakout feature.

 

The supplied large diameter is 1.350" (34.29mm) and the small diameter is 0.900" (22.86mm). After heat shrinking, both the large and small ends recover to 0.450" (11.43mm). The total recovered length is 4.740" (120.40mm), with the large and small recovered lengths each being 2.370" (60.20mm).

 

This boot is listed as RoHS3 Compliant, REACH Unaffected, and MSL Level 1 Unlimited, though these compliance claims are unverified. The product belongs to the NBC molded parts family and is commonly used in conjunction with connectors and cables requiring environmental sealing and strain relief.
