The ALLIED AIR 19X70 is a RAST 6-pin terminal block connector used in low-voltage wiring harness applications within residential HVAC systems. This connector provides a secure, insulation-displacement-style termination point for control wiring, allowing technicians to make reliable, repeatable connections between control boards and wiring harnesses. At 2 inches in length and 1 inch in both height and width, the 19X70 is a compact component weighing 0.3 pounds. It is typically installed by HVAC technicians during control board replacement, wiring harness repair, or unit commissioning work.
This terminal block connector is suited for residential HVAC control circuit applications where RAST-style connectors are specified. It is commonly encountered during service calls involving furnace or air handler control boards that use plug-in wiring harness connections. The compact footprint makes it appropriate for tight wiring compartments typical of modern residential equipment.
Designed as an OEM-style replacement RAST 6-pin terminal block connector for compatible ALLIED AIR residential HVAC equipment using LB-107734D wiring harness connections.
Installation should be performed by a qualified HVAC technician. Disconnect and lock out all power to the unit before handling any control wiring or connector components. Verify connector orientation and pin alignment before seating the connector to avoid damaging the control board header. Follow all applicable NEC and equipment manufacturer wiring guidelines during service.
