The 24 V DC coil is the control voltage you need to match against your PLC or relay output — at that rated value, the auxiliary contacts handle 6 A, enough for signaling back to a controller or driving a small pilot light. The contactor is rated for up to 1 000 switching cycles per hour under AC-3 duty (motor starting), which is standard for conveyor and pump applications; drop to 300 cycles per hour under AC-4 (plugging/reversing) if you are doing frequent inching or reversing.
Depth is 151 mm, height 85 mm — check your enclosure depth before committing. The screw-type terminals on the magnet coil accept solid or stranded wire from 1 to 10 mm², and the auxiliary/main contact terminals take 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²).
