The LX4D6DD is a replacement contactor coil from the Schneider TeSys range, designed to fit LX1D6 contactors. It operates on a 96 V DC control circuit, drawing current determined by its 51.9 Ohm resistance at 20 °C and 4.18 H inductance when the contactor is closed. Rated for 10 Mcycles mechanical durability and a maximum operating rate of 3600 cycles per hour at 60 °C, this coil suits high-cycling applications like conveyor sorting stations or packaging machinery where the contactor opens and closes repeatedly across a shift.
Coil suppression — what the listing tells you
This coil ships without a built-in suppressor module. That means the installer must add an external flyback diode or RC snubber across the coil terminals to suppress the inductive kickback when the DC circuit opens. Without it, the voltage spike can damage PLC output cards or relay contacts driving the coil. The 4.18 H inductance of the closed circuit gives a stored energy of roughly 0.5 J at 96 V — enough to arc across a relay contact if unsuppressed. A standard 1N4007 diode reverse-biased across the coil handles this, but verify polarity: cathode to positive rail.
