Overview
The Hammond Manufacturing 162D120 is a laminated core power transformer designed for PCB mounting. It features a low-profile, split bobbin construction with dual non-concentrically wound secondaries. The unit operates at 50/60 Hz and provides a primary voltage of 115V or 230VAC in parallel configuration. Secondary outputs include 60V (parallel), 120V (series), or 120V center-tapped (parallel). The rated power capacity is 1.1VA with a secondary current rating of 20mA.
Feature Summary
- Low profile design utilizing a split bobbin structure
- Dual winding secondaries configured for non-concentric winding
- Laminated core construction for standard power transformation
Applications
- Low voltage PCB mounting applications
- Industrial control panel power supplies
- Equipment requiring isolated AC power conversion
Procurement Notes
Verify the specific pinout and mounting hole dimensions against your PCB layout before ordering. Confirm that the 1.1VA power rating meets the load requirements of your circuit. Ensure the primary voltage selection matches the available line voltage. Check for any required factory modifications if standard cutouts are needed.
Selection Notes
Select this component when space constraints require a low-profile transformer. Choose this model if dual secondary voltages are necessary for different circuit rails. Ensure the application does not exceed the 20mA secondary current limit. Verify compatibility with 115V or 230V input sources.
Part Context
This part belongs to the Hammond Manufacturing 162 series of power transformers. The series is characterized by open-frame designs suitable for direct board integration. These units are commonly used in industrial electronics where compact size and reliable isolation are prioritized over high power output.
Replacement Considerations
No public confirmed substitute part numbers are identified in the provided documentation. Users should verify electrical equivalence and mechanical fitment carefully when considering alternative components from other manufacturers.
