What This 3-Position Block Does on the Board
The TE Connectivity 2834078-2 is a 3-position PCB-mount terminal block with a 0.197" (5.00 mm) pitch and a 45° (135°) wire entry angle — the angled exit keeps the wire bundle low against the board, useful in shallow enclosures or where the adjacent component clearance is tight. Each level accepts 14-28 AWG stranded or solid wire into a screwless spring-cage clamp; push the wire in, the tension clamp grabs it, no tool needed for termination. Rated 16 A per position at 300 V, it handles control-circuit power or field-wiring runs inside industrial panel equipment.
Spring-Cage Termination — No Screws, No Torque Spec
The 2834078-2 uses a screwless spring-cage (tension clamp) mechanism. Strip the wire to the recommended length, push it into the clamp opening, and the spring holds it against the current bar. No screwdriver calibration, no risk of over-torque cracking the housing. For solid wire or ferruled stranded, the spring maintains contact force across temperature cycles. The side interlocking feature lets you gang multiple blocks side-by-side on the same pitch without gaps — useful when you need more than three positions on a single rail.
