Product Details
- 01 Barrier-type screw terminal interface — 4 independent pairs
Each of the 4 pairs consists of two M3 wire-binding screws connected by a copper conductor. Adjacent pairs share a common insulating barrier and are not electrically connected. Accepts solid or stranded copper wire (0.5 – 1.5 mm2 / 22 – 16 AWG) — strip, insert, and tighten to 0.6 – 0.9 Nm. - 02 ABS insulating body with transparent PVC cover
Body molded from ABS. Transparent PVC cover (54.4 x 21.89 x 14.85 mm overall) fits over the terminal area to help reduce accidental contact with live terminals while keeping terminations visible for inspection. - 03 Panel-mount design with 39.2 mm mounting pitch
Two reinforced mounting flanges with 39.2 mm hole spacing allow screw-fastening to a suitable flat surface (panel, chassis, or equipment board). Overall footprint: 54.4 x 21.89 x 14.85 mm. Numbered position markers assist wiring identification.

Typical wiring applications
Point-to-Point Wire Termination
Routed as field-wiring terminations inside control panels, junction boxes, and machinery where each screw pair serves a separate circuit leg without bridging.
Control-Panel Circuit Interconnection
4 independent connection points for organizing relay coil wiring, sensor returns, pilot-light circuits, and auxiliary contact wiring inside industrial enclosures.
Harness-to-Panel Connection
Serve as the transition point between cable harness assemblies and fixed equipment wiring in mobile electrical systems (marine helm, RV battery compartments, off-road vehicle dash panels) and stationary automation racks.
Application examples describe common installation contexts. Verify the rated voltage, current, temperature, and environmental conditions match your specific application.
