Simplex 4081-9019 — end-of-line resistor harness in the Simplex 4081 Series, a single resistor pre-assembled between two flying leads.
A 4081 harness terminates a Class B circuit at a remote device instead of inside the control unit: the resistor is crimped between two leads and sealed under heat shrink, so the technician lands stripped conductors rather than a bare axial resistor. Simplex publishes no resistance or wattage for 4081-9019, so none is stated here — take the value from the panel field wiring diagram.
- Class B end-of-line resistor harness, UL Listed to Standard 864
- Overall length about 9-1/2" (241 mm); wire length 7" (178 mm)
- 18 AWG, 600 V black insulation; leads stripped 0.5" (13 mm), tinned
- Not listed in Simplex datasheet S4081-0003 Rev. 2, whose table runs 4081-9001 to 4081-9018 plus 4081-9026
Order against the value on your drawings: neighbouring numbers differ only in resistance, and 4081-9020, 4081-9021 and 4081-9022 are four-wire MX harnesses for 4090 Series modules.
