Closed-End Crimp Connector 100-Pack

The 3M S-11-A Scotchlok connector joins copper wires in a closed-end nylon housing. It accepts combinations from two 22 AWG conductors up to 16 AWG. The pack of one hundred suits electricians and maintenance teams who need a consistent supply for panel work or field repairs.

Nylon Insulation and Tool Compatibility

The natural nylon body provides insulation rated from minus 40 to 221 degrees Fahrenheit and up to 600 volts. Copper contacts are crimped using TH-440 or TH-450 installation tools. These specifications mean the connector meets UL and CSA requirements without additional taping or heat-shrink steps.

Wire-Range and Temperature Limits

The connector handles a maximum wire size of 16 AWG and a minimum of 22 AWG, with an overall length of .83 inches. It is not suited for conductors larger than 16 AWG, for voltages above 600 V, or for environments exceeding 221 degrees Fahrenheit. Buyers needing larger gauge terminations or higher temperature ratings must select a different connector style.

Questions about this item

Does the nylon insulation on these S-11-A connectors become brittle and need replacement after years at the 221°F maximum rating?

The nylon is rated for continuous operation up to 221°F and down to -40°F; it does not require scheduled replacement unless physical damage or discoloration appears during inspection.

When crimping the maximum 16 AWG copper wires, does the copper contact or the nylon body reach its limit first?

The copper contact and nylon insulation share the 600 V, 221°F ratings, so neither component has a lower sustained-use limit; both are within specification at the maximum 16 AWG combination.

Will the TH-440 or TH-450 tool heat up noticeably when installing all 100 connectors in one session?

The TH-440 and TH-450 are hand-operated crimp tools; they generate no operational heat and produce only the mechanical click of each crimp during extended use.
