Overview

The Daniels Manufacturing Corporation (DMC) AF8 (M22520/1-01) is an adjustable hand crimp tool designed for precision crimping of electrical contacts. This datasheet provides comprehensive information regarding its function, technical specifications, usage, and maintenance.

Function Description

The AF8 tool is a basic hand crimp tool without a positioner, meaning a separate positioner attachment is required for specific crimping applications. Its primary function is to securely crimp electrical contacts onto wires within a specified gauge range. The tool features a double-action ratchet mechanism, which ensures that the crimping cycle is completed once initiated, preventing partial crimps and enhancing reliability. This design means the tool cannot be opened until the full cycle is finished.

When a positioner is installed, the tool facilitates precise crimping by allowing the user to select the appropriate setting based on the contact's part number and wire size. The positioner guides the contact and wire into the indenter opening, ensuring consistent and accurate crimps. The tool's operation involves inserting the contact and prepared wire, then squeezing the handles until the ratchet releases, at which point the handles will return to the open position.

Important Technical Specifications

  • Designation: AF8 (M22520/1-01) – refers to the basic tool without a positioner.
  • Wire Crimp Range: 26 to 12 AWG. This broad range allows for versatility across various applications.
  • Ratchet Mechanism: Double-action, ensuring full crimp cycle completion.
  • Positioner Compatibility: Designed to work with specific positioners (e.g., those with color-coded inserts) that align with the tool's retaining ring and alignment pin.
  • Inspection Gage: The tool's performance can be verified using inspection gages. For example, the G125 (M22520/3-1) gage is used on selector setting #4.
    • "GO" Gaging: The "GO" gage end must pass freely between the indenter tips when the tool is fully closed and under firm hand pressure.
    • "NO-GO" Gaging: The "NO-GO" gage end may partially enter but must not pass completely through the indenter opening under the same conditions.
  • Gaging Limits (Ø ±.0001):
    • SEL NO 1: GO .0280, NO-GO .0330
    • SEL NO 2: GO .0320, NO-GO .0370
    • SEL NO 3: GO .0360, NO-GO .0410
    • SEL NO 4: GO .0390, NO-GO .0440
    • SEL NO 5: GO .0450, NO-GO .0500
    • SEL NO 6: GO .0520, NO-GO .0570

Crimping Instructions:

  3. Remove the positioner with a straight lifting motion.
