SPECIFICATIONS & CROSS-REFS — SPDT (1 Form C) 5-pin mini ISO; 12V coil; 40A (NO) / 30A (NC) @14V; 75VDC max switching; coil power 1.6W; operating −40~125 °C; terminals 0.250″ quick-connect. Ordering code mapping: 1C=SPDT, C1=plastic bracket, 12S=12V sealed, RN=internal resistor, –X=RoHS. Cross-reference for selection: Omron G8JN-1C7T-MF-R-DC12; American Zettler AZ9731-1C-12DC2E.
INSTALLATION & LOCATION — Plugs into a 5-pin mini ISO socket in the fuse/relay box (engine bay or under-dash). Pinout (bottom view): 30 common, 87 NO, 87a NC, 85/86 coil. RN = resistor (non-polar); DN = diode (observe polarity). Confirm socket layout and suppression type before power-up.
EQUIPMENT COMPATIBILITY (BY OE NUMBER) — Compatible with OE 6679820 (for Bobcat equipment; Omron supplier No. G8JN-1C7T-R-DC12). Common model families using 6679820 include S-Series skid-steers S510, S530, S550, S570, S590, S630, S650, S750, S770, S850 and T-Series compact track loaders T550, T590, T630, T650, T750, T770, T870(verify by serial/parts catalog before purchase).
ADDITIONAL BOBcat MODELS (6679820) — Also listed for earlier families such as 751, 753, 763, 773, 863, 864, 873, 883, 963, S100, S130, S150, S160, S175, S185, S205, S220, S250, S300, T110, T140, T180, T190, T200, T250(applications vary by year/trim; always match the OE and socket form).
DURABILITY FOR ENGINE-BAY USE — Sealed case, high dielectric strength (500 Vrms) and ≥100 MΩ insulation; typical operate 7 ms / release 2–5 ms. Suited for A/C clutch, ECM/main, fan, horn/lock and other SPDT changeover circuits when amperage/specs match.
COMPLEMENTARY PARTS (MATING SOCKETS/HARNESSES) — Works with 5-pin mini-ISO relay connectors such as TE Connectivity 3-1393310-7 (mini-ISO socket), Waytek 75340 / 75610 weather-resistant connectors, or CIT Relay HD-1002 interlockable harness. Adding a matching socket improves serviceability and strain relief.
WHAT YOU GET — 1× 12V SPDT 5-pin mini ISO sealed relay with plastic mounting bracket; non-OEM replacement built to the mini-ISO footprint. Always compare the OE number, pin layout and suppression type before installation.
