Honeywell 15PA107 Locking Ring for EN Series Sealed Switch Assemblies
The Honeywell 15PA107 locking ring is a targeted accessory for EN Series sealed switch maintenance and replacement work. It is not a complete switch and should not be treated like a standard switch body in product selection. Instead, the Honeywell 15PA107 sealed switch accessory is intended for a defined mechanical role within compatible switch assemblies, especially where exact fit and thread compatibility matter.
What Is the Honeywell 15PA107?
Honeywell’s EN replacement parts order guide lists the 15PA107 as a locking ring only for 622EN and 624EN series products with a 15/32 in bushing. DigiKey likewise categorizes it as an active accessory and identifies its accessory type as a locking ring for the same series. That makes the 15PA107 a highly specific maintenance component rather than a general-purpose industrial hardware item.
Why a Locking Ring Matters in Sealed Switch Systems
In sealed switch assemblies, the locking ring helps secure the switch in place and supports correct mechanical installation. Even though it is a relatively small component, it can affect positional stability, mounting consistency, and long-term reliability in the field. A missing or damaged locking ring may lead to poor retention, misalignment, or service interruptions, especially in equipment exposed to movement, vibration, or repeated operation.
That is why many buyers search phrases such as Honeywell 15PA107 industrial switch accessory or Honeywell 15PA107 locking ring for sealed switch. They are usually trying to restore the original installation standard of a 622EN or 624EN assembly rather than change the switch design itself.
System Context and Compatibility
The broader EN Series is associated in Honeywell literature with environmentally sealed limit switch construction and demanding-duty applications. The platform includes standard temperature coverage from -54°C to +85°C, with certain high-temperature variants extending to +125°C. The Honeywell 15PA107 must therefore be selected in direct relation to the compatible host switch family, not only by appearance.
Best Use Cases
The Honeywell 15PA107 locking ring is most relevant for MRO activity, aviation-related or specialty sealed-switch maintenance programs, legacy equipment support, and precise parts replacement in installed EN systems. It is especially useful when technicians need the original locking function without replacing the full switch assembly.

FAQ
Is Honeywell 15PA107 a complete switch?
No. It is a locking ring accessory only.
Which switch series use Honeywell 15PA107?
It is listed for 622EN and 624EN series applications with a 15/32 inch bushing.
Why would someone replace a 15PA107 locking ring?
Replacement is typically needed when the original part is worn, damaged, missing, or no longer securing the switch correctly.
Can Honeywell 15PA107 be treated as a universal locking ring?
No. It should be matched to the specified Honeywell switch series and bushing configuration for proper fit.
What is the main benefit of using the correct Honeywell 15PA107 accessory?
The main benefit is preserving correct mechanical retention and avoiding fitment issues in sealed switch assemblies that require exact hardware compatibility.
