166J8

Overview

The Hammond Manufacturing 166J8 is an industrial power transformer designed for low voltage applications. It features a single primary winding rated at 115 VAC and a single secondary winding providing 8.5 VAC center-tapped output. The unit delivers a power rating of 8.5 VA with a secondary current capacity of 1 A. Designed for chassis mounting, it operates within a temperature range of 0°C to +130°C and supports frequencies of 50 Hz or 60 Hz. Physical dimensions are 71.4 mm in length, 38.1 mm in width, and 35.1 mm in height, with wire lead termination.

Feature Summary

• Single primary and single secondary winding configuration for standard control circuit isolation
• Chassis mount design with wire leads for direct integration into industrial enclosures
• High thermal tolerance supporting operation up to +130°C for demanding environments

Applications

• Industrial control panel power supply
• Low voltage equipment isolation
• Machine tool control circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required insulation classes and regulatory certifications. Confirm that the wire lead length and gauge meet the installation requirements. Cross-reference the part number with the latest Hammond Manufacturing documentation to validate current production status and any potential design updates before finalizing procurement orders.

Selection Notes

Select this component when a compact, chassis-mountable transformer is required for 115V primary systems. Ensure the 8.5 VA load does not exceed the rated capacity to maintain thermal stability. Verify that the 8.5V CT secondary voltage aligns with downstream control device specifications. Consider the physical footprint constraints within the enclosure to ensure proper fitment alongside other components.

Part Context

The 166J8 belongs to the Hammond 166 series of industrial control transformers. This series is characterized by laminated core construction and robust performance for general-purpose industrial applications. The model represents a specific tap configuration within the broader family of low-voltage power transformers offered by Hammond Manufacturing for control circuitry.

Replacement Considerations

Consult Hammond Manufacturing technical literature for verified substitute part numbers within the 166 series that match identical electrical ratings and mechanical dimensions. Direct replacement requires confirmation of equivalent VA rating, voltage taps, and mounting style.
