TB25-301/5.0 and TB25-301R/5.0 provide screw connections in a single row with 2–24 poles. The 301 has side wire entry and screws accessed from above; the 301R has top wire entry and screws accessed from the side. Both use through-hole solder pins, with different pin projections and PCB edge references.
