Push-In Terminal Block for Panel Wiring
It uses a screwless push-in spring termination — strip the wire, push it in, and the leg spring locks it. The white thermoplastic housing includes an integral cover that snaps over the wire entries, providing basic dust protection and touch-safety inside an enclosure. Rated for 320 V and accepting 18-24 AWG wire, this block suits control cabinet wiring for sensors, actuators, and moderate-power distribution where a compact 2-position termination point is needed.
Board Cutout Fit and Pitch
The 0.256" (6.50mm) pitch is the centre-to-centre spacing between the two positions. This is wider than typical 5.08 mm terminal blocks, so the board cutout profile is specific to this series. The mounting type is Board Cutout, Surface Mount — the block drops into a rectangular cutout in the PCB and solders to surface pads on the board. Board layout engineers need the cutout dimensions from the product drawing, not just a drill pattern.
Wire Termination and Field Service
The screwless leg spring termination means no screwdriver is needed for wiring. Strip the conductor to the correct length, push it into the entry, and the spring grips the wire. This is field-repairable — a service tech can re-terminate a wire on site with just a wire stripper. The 18-24 AWG range covers common signal and control wiring: 24 AWG for sensor signals, 18 AWG for 24 VDC actuator power. The mating orientation is horizontal with the board, bottom entry — wires enter from below the PCB, parallel to the board surface.
Voltage and Temperature Rating
Rated 320 V, this block handles line-voltage AC or higher DC bus levels — not just 24 V control signals. It is suited for indoor climate-controlled cabinets; for unheated outdoor enclosures or environments below -25°C, a wider-range block would be needed. The housing material is thermoplastic, and the contacts are copper alloy with tin plating — adequate for connections that are terminated once and left in service.
Comparison with 1-Position Sibling
The closest sibling in the same series is the 1-2834331-1, which is identical in pitch (0.256"/6.50mm), voltage (320 V), wire range (18-24 AWG), termination style, mounting, and colour (white). The only difference is positions per level: 2 positions on the 1-2834331-2 versus 1 position on the 1-2834331-1.
