Overview
The Hammond Manufacturing 166G12 is a low voltage industrial power transformer designed for chassis mounting. It features a single primary winding rated at 115 VAC and a single secondary winding providing 12.6 VAC center-tapped output. The unit has a power rating of 6.3 VA with a maximum secondary current of 0.5 A. Operating at 60 Hz, it utilizes wire leads for termination. The physical dimensions are 71.37 mm in length, 38.1 mm in width, and 42.93 mm in height.
Feature Summary
- Chassis mount design with wire lead terminations
- Single primary to single secondary winding configuration
- Low voltage center-tapped secondary output
- Industrial control transformer classification
Applications
- Industrial control panels
- Low voltage rectifier circuits
- Equipment requiring isolated AC power supply
- Chassis-mounted electronic assemblies
Procurement Notes
Verify the specific suffix against official documentation, as bulk packaging variants may exist. Confirm that the required voltage frequency matches the 60 Hz specification. Ensure chassis mounting space accommodates the specified dimensional envelope. Check for regional shipping restrictions related to product weight or size before ordering.
Selection Notes
Select this component when a 6.3 VA capacity is sufficient for the load requirements. The 12.6 VAC center-tapped output is suitable for full-wave rectification applications. Verify that the 115 VAC primary input aligns with the available power source. Consider the chassis mounting style and wire lead termination method for integration into the target enclosure design.
Part Context
This part belongs to the Hammond 166 series of industrial power transformers. The series offers various power ratings and voltage configurations while maintaining consistent chassis mounting characteristics. The 166G12 represents a lower power option within the lineup, distinguished by its specific 6.3 VA rating and 12.6 VAC center-tapped secondary output.
Replacement Considerations
Consult official Hammond Manufacturing cross-reference documents for verified substitute part numbers. Do not assume functional equivalence based on similar voltage ratings alone. Verify that any alternative component meets the same mechanical mounting and electrical isolation requirements.
