What is the TE Connectivity 281783-4?
It uses a 0.100" (2.54 mm) pitch, single-row layout, and terminates discrete 24-26 AWG wire via insulation displacement — no crimp tool or loose contacts needed. The tin-plated female sockets mate with standard 0.025" square header pins. A detent lock holds the plug in place once mated, giving a positive tactile click on engagement. The blue housing makes it easy to spot on a harness or in a panel.
What wire gauge does 281783-4 support?
It accepts 24-26 AWG discrete wire. No wire prep beyond stripping is needed.
Where is this connector used?
This is a wire-to-board plug for internal harnesses in consumer electronics, industrial controls, and appliance applications. The 0.100" pitch and 4-position count suit low-signal-count connections — sensor inputs, control lines, or low-current power distribution. The detent lock gives vibration resistance for equipment that sees occasional movement or transport.
