Enraged Rabbit Carrot Feeder Toolhead Sensor Kit

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.
