Overview
The Hammond Manufacturing 166F2 is a low voltage industrial power transformer featuring a laminated core and chassis mount style. It operates at 50 Hz/60 Hz with a single primary winding rated for 115 VAC input. The secondary output provides 2.5 VAC center-tapped configuration, delivering a maximum current of 250 mA. The unit has a power rating of 0.63 VA and utilizes wire leads for termination. Physical dimensions are 52.32 mm in length, 31.75 mm in width, and 30.23 mm in height.
Feature Summary
- Laminated core construction for stable power transformation
- Single primary and single secondary winding design
- Chassis mounting style with wire lead terminations
Applications
- Industrial control circuits requiring low voltage AC power
- Equipment needing 2.5V center-tapped supply
- General purpose power transformation in enclosures
Procurement Notes
Verify the specific part number suffix against official Hammond Manufacturing documentation to ensure correct voltage and current ratings. Confirm that the 115V primary specification matches your system requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure physical dimensions fit the intended chassis space before procurement.
Selection Notes
Select this component when a compact 0.63 VA transformer is needed for 115V to 2.5V CT conversion. Consider the chassis mount style and wire lead termination method for integration. Evaluate the operating temperature range and insulation requirements against application constraints. Compare physical size constraints with alternative models in the 166 series if space is limited.
Part Context
This model belongs to the Hammond 166 series of industrial control transformers. The series offers various power ratings and voltage configurations while maintaining consistent mounting styles. These transformers are designed for reliable performance in industrial environments. The 166F2 represents a lower power option within the lineup suitable for small signal or control applications.
Replacement Considerations
Check Hammond 166F8 or 166C12 for similar form factors with different voltage outputs. Verify electrical compatibility before substituting any other manufacturer's components. Ensure replacement parts meet the same safety and regulatory standards.
