202K121-3-0 Description

Short technical summary and product information.

The 202K121-3-0 is a heat shrink boot manufactured by TE Connectivity. It is made from semi-rigid polyolefin material and is black in color. The boot features flame retardant properties and an integral lip for enhanced sealing and strain relief. It is designed for shell size 21 applications.

 

The boot has a supplied diameter of 23.9mm on both large and small ends. After recovery, the large diameter reduces to 10.39mm and the small diameter to 5.59mm. The total recovered length is 38.0mm, with a large recovered length of 21.08mm and a small recovered length of 13.0mm. These dimensions make it suitable for protecting cable entries and connector backshells in demanding environments.

 

Typical applications include cable sealing, strain relief, and environmental protection in industrial, automotive, and aerospace systems. The flame retardant feature adds safety in high-temperature or fire-risk scenarios. The lip design helps secure the boot over connectors or cables.
