Toolhead Hall-effect sensor hardware for ERCF builds. This kit bundles the core sensing parts used for an Enraged Rabbit Carrot Feeder toolhead filament sensor: AH3364Q-P-B SIP Hall sensor, a ferromagnetic M3 DIN125 washer, 6 × 3 mm neodymium magnet, and JST-XH 3-pin connector hardware.

Why this kit exists

  • The official ERCF project calls for an AH3364Q-P-B Hall-effect sensor in SIP-3 form; the FAQ explicitly warns to use AH3364 rather than substitute Hall sensors.
  • The washer must be magnetic: ERCF documentation specifies steel M3 DIN125, not stainless, so the Hall sensor can trigger reliably.
  • The magnet is the small 6 × 3 mm round neodymium style used for the toolhead sensor mechanism; ERCF notes recommend strong N51/N52-class magnets.

Kit contents

  • 1× AH3364Q-P-B Hall Effect sensor, SIP package
  • 1× M3 DIN125 steel washer
  • 1× 6 × 3 mm round neodymium magnet
  • 1× JST-XH 3-pin male connector
  • 4× JST-XH crimp pins

Fitment

Use this with an Enraged Rabbit Carrot Feeder build when adding the toolhead Hall sensor, especially Galileo/Clockwork-style ERCF toolhead sensor setups. It also pairs with Enraged Rabbit Carrot Patch buffer hardware and JST-XH connector tooling if you are wiring more than one printer harness.

Not included / gotchas

  • This is not a complete ERCF kit, printed-part set, board, or cable harness.
  • Do not swap in a stainless washer; ERCF documentation calls out stainless washers as a failure mode because they are not ferromagnetic enough.
  • Use the SIP through-hole Hall sensor form, not the SMD package, unless your printed/toolhead parts explicitly support it.

Shipping:

US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time. 

International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs. 

I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost. 

If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement. 

Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
