167M20

Overview

The Hammond Manufacturing 167M20 is a laminated core power transformer designed for industrial control applications. It features an enclosed chassis mount construction with wire lead terminations. The unit operates at 50 Hz/60 Hz with a single primary winding rated at 115 VAC and a single secondary winding providing 20 VAC center-tapped output. The maximum power rating is 60 VA, supporting a secondary current of 3 A. Physical dimensions are 55.6 mm in length, 66.8 mm in width, and 66.8 mm in height, weighing approximately 861.8 g. It functions within a temperature range of 0°C to +130°C.

Feature Summary

• Enclosed chassis mount design for secure installation
• Laminated core construction for efficient power transfer
• Single primary and secondary winding configuration
• Center-tapped secondary voltage output

Applications

• Industrial control panels
• Low voltage filament circuits
• Chassis-mounted equipment power supplies

Procurement Notes

Verify the specific datasheet version for the 167M20 model to confirm insulation class and regulatory compliance status such as RoHS. Ensure the application environment supports the specified operating temperature range up to +130°C. Confirm that the wire lead termination style matches the system wiring requirements. Check for any regional certification differences if importing from non-domestic sources.

Selection Notes

Select this component when a 60 VA capacity is required for 115 VAC input systems. The 20 VAC center-tapped output suits applications needing balanced low voltage distribution. Consider the physical footprint of 55.6 x 66.8 x 66.8 mm for enclosure space constraints. The chassis mount style requires appropriate mounting hardware for vibration resistance.

Part Context

This transformer belongs to the Hammond 167 series of industrial power transformers. The series offers various power ratings and voltage configurations while maintaining consistent chassis mount dimensions and construction quality. It serves as a standard solution for general-purpose isolation and voltage transformation in industrial settings.

Replacement Considerations

Direct substitutes include other Hammond 167 series models with identical electrical specifications. Verify cross-compatibility with equivalent transformers from other manufacturers by matching VA rating, voltage, and physical dimensions.
