You can also use type PMV20XNER or AO3400A or AOSS32334C which have a higher peak current rating and are fitted as standard in recent production Duets. The original part number on most Duets is PMV40UN2 or PMV40UN2R which is available from the usual electronic component distributors such as Farnell/Newark/element14, Digikey, Mouser and RS.

If you short out a PWM fan, the fan driver mosfet will burn out. Here are the compatible part numbers: Part In general you should use crimp pins and shells from the same manufacturer to ensure compatibility.

In particular, they will not lock into Molex 22-01-20x5 shells. The crimp pins made by Würth should only be used with shells made by Würth. Please note that the shells and crimp pins that supplied with Duets are usually made by Würth Elektronik. The commonly available KF2510 connector kits also fit quite well and include extra pieces for future expansion. There are compatible connectors available from Würth Elektronik and JYK. Molex KK connectors are widely available from the usual electronic component distributors, and on eBay. However, for maximum reliability we recommend using the correct Molex female connectors or compatible connectors, because they lock in place and will only fit one way round. The Dupont-style connectors typically used with RAMPS and other electronics will also fit them. The connectors for the stepper motor, endstop switch, thermistors and fans on the Duet 2 are Molex KK type. (many alternatives are available, for example from suppliers on eBay). The fork connectors for the power supply are a generic "blue" max 2.5mm^2 like this version from RS. Crimps for the above: BVH-21T-P1.1B (JST) or VH396T-L (Valcon)Ħ-pin SWD connector (JST ZH) : ZHR-6 note it is normally easier to buy a pre crimped tail and JST ZH are quite fiddly to crimp).4 way shell VHR-4N (JST) or VH396-04H (Valcon).2 way shell VHR-2N (JST) or VH396-02H (Valcon).
#MOLEX CONNECTOR PURPOSE SERIES#
Stepper motor (4-pin) and medium-current (2-pin) outputs: JST VH series or compatible: Please note, the Molex KK compatible shells and crimp pins that we supply with Duets are usually made by Würth Elektronik. These are widely available from the usual electronic component distributors, and on eBay. Connectors used on 6HC Mainboard and 3HC ExpansionĢ.54mm Molex compatible connectors are used for everything except stepper motor and medium-current outputs.
