The LX1D2V5 is a replacement coil for the TeSys D contactor range, specifically the 400 V AC 50 Hz variant intended for 9 to 18 A frame contactors. It is an AC-operated coil with no built-in suppressor module, so an external RC snubber or varistor is your call depending on the PLC output driving it.
Coil draws 60 VA inrush at 50 Hz (cos φ 0.75) and holds at 7 VA (cos φ 0.3) — the inrush-to-hold ratio is about 8.5:1, which matters if your control transformer is sized tight or shares a circuit with other inductive loads. Operational voltage range is 0.8 to 1.1 times Uc at 50 Hz (320 to 440 V AC) up to 55 °C ambient; outside that band the coil may not pull in reliably or could overheat on sustained overvoltage. Average DC resistance is 2069 Ω at 20 °C — a quick bench check if you suspect a winding short.
