Locating Devices (Positioners, Turrets & Locators)
Precision alignment tools engineered for consistent, repeatable, spec‑compliant crimping.
Locating devices—also known as positioners, turrets, or locators—are critical accessories used with military‑grade and commercial crimp tools. Their purpose is to position the contact at the exact depth and orientation required for a proper crimp. This ensures every termination meets electrical, mechanical, and MIL‑SPEC requirements.
These tools are widely used across MIL‑DTL‑38999, AS39029, D‑Sub, Micro‑D, and other high‑reliability connector systems. Whether you’re working in aerospace, defense, industrial manufacturing, or harness assembly, the correct locating device is essential for producing consistent, repeatable results.
What Locating Devices Do
- Hold the contact at the precise insertion depth
- Maintain axial alignment during crimping
- Prevent over‑crimping or under‑crimping
- Ensure repeatable, spec‑compliant results
- Match specific contact sizes, connector families, and tool frames
Types of Locating Devices
Fixed Positioners – Single‑application locators for a specific contact size or connector series
- Turret Heads – Multi‑position rotating heads supporting several contact sizes in one device
- Adjustable Positioners – For applications requiring variable depth settings
Why They Matter
A crimp tool is only as accurate as the locator guiding it. Using the correct locating device ensures:
- Proper electrical performance
- Mechanical reliability
- Compliance with MIL‑SPEC and OEM requirements
- Reduced rework and scrap
- Consistent results across technicians and shifts
❓ Locating Devices – FAQ
What is a locating device?
A locating device—also called a positioner, turret, or locator—is an alignment accessory used with crimp tools to hold the contact at the correct depth and orientation during crimping. It ensures consistent, spec‑compliant terminations.
Do I need a specific locator for each contact size?
Yes. Most locating devices are designed for a specific contact size (such as 12, 16, 20, or 22D) and sometimes for a specific connector family. Using the correct locator ensures proper crimp depth and prevents damage to the contact.
What’s the difference between a positioner and a turret?
A positioner is typically a single‑application locator designed for one contact size or connector series. A turret head is a rotating multi‑position device that supports multiple contact sizes in one unit.
Are locating devices required for MIL‑SPEC crimping?
Yes. For MIL‑DTL‑38999, AS39029, and other high‑reliability connector systems, the correct locating device is required to meet the specification and ensure repeatable, compliant crimps.
How do I know which locator fits my crimp tool?
Each crimp tool frame (such as Daniels, Astro, or generic indent‑style tools) has a list of compatible positioners or turret heads. Match the locator to both the tool frame and the contact size you’re working with.
Can I use one locator for multiple connectors?
Sometimes. Turret heads support multiple contact sizes, but fixed positioners are usually designed for a specific connector family or contact type. Always check compatibility before crimping.
What happens if I crimp without a locator?
Crimping without the correct locator can result in:
- Incorrect crimp depth
- Misalignment
- Poor electrical performance
- Failed pull‑tests
- Out‑of‑spec terminations
Using the proper locator ensures accuracy and repeatability.
Are locating devices universal across brands?
Not always. Many positioners are brand‑specific. Some generic equivalents exist, but compatibility must be verified by tool frame and contact size.
