2-Position Push-In Spring Terminal Block for Signal Wiring
The 1986720-2 is a 2-position plug with female sockets from TE Connectivity's terminal block line, designed for 3.81 mm pitch headers. Rated at 9 A and 300 V UL, it uses a screwless push-in spring termination that accepts 14-30 AWG wire (0.05-2 mm²). Side stacking allows ganging multiple 2-position plugs into a wider terminal block assembly without extra hardware, simplifying multi-circuit builds. The 180° wire entry means cables exit straight out the back, which helps in shallow enclosures or when routing wires along a cable tray.
Current, Voltage, and Wire Range — What Fits
At 9 A per circuit, the current rating is set by the tin-plated copper alloy contacts and the 3.81 mm pitch. For continuous duty at 110°C ambient, derate per the UL current-temperature curve; in a 50°C cabinet the plug can run at full 9 A without exceeding the 30°C temperature rise limit of the housing material. The 300 V UL rating covers most industrial control voltages up to 277 VAC line-to-neutral. The 11.66 mm insulation height provides adequate creepage distance for pollution degree 2 environments. Wire range 14-30 AWG (0.05-2 mm²) accepts both solid and stranded conductors; the spring cage grips the full conductor cross-section without cold flow.
Side Stacking and Free-Hanging Mounting
Side stacking is a key feature: each 2-position plug can be interlocked with an adjacent plug of the same series to form a multi-position assembly. No additional hardware or tools are needed — the plugs snap together side-by-side, increasing the circuit count while maintaining the 3.81 mm pitch. Free hanging (in-line) mounting means the plug is not board-mounted; it mates with a PCB header or receptacle. The 180° wire entry keeps the cable path straight, which is useful for wire routing in control cabinets or terminal boxes where space is tight.

Peer Comparison — Similar TE Terminal Block Plugs
Peer parts 1-2213934-1, 1-2305909-1, and 1-2213935-1 are also active TE terminal block plugs in bulk packaging. They may differ in position count (e.g., 3 or 4 positions) or pitch; the 1986720-2 is a 2-position, 3.81 mm pitch variant. If your BOM requires more circuits, one of these peers may be a direct fit without changing the termination style or housing material.
