What Is the Electric Carrier Signal Panel Twist-Plate?

The Electric carrier signal panel 14/15T F4-1/U 6140 twist-plate is a mechanical mounting and alignment component used in electric carrier signal panel assemblies. It features an inner hole diameter of either 16mm or 20mm (selectable by variant) with an outer circle dimension of 50mm to 58mm, depending on the chosen configuration. This twist-plate serves as a rotational alignment element — it allows a signal panel component to be rotated into position and then locked, providing both mechanical retention and precise angular positioning.

In short: This is a mounting twist-plate for electric carrier signal panel assemblies, available in three bore/outer-diameter combinations. If you are replacing a worn or damaged plate on a signal panel fixture, match your existing dimensions to one of the three variants before ordering.

How to Select the Correct Variant

This product is available in three configurations. The critical dimensions are the inner hole (bore) diameter and the outer circle (overall) diameter. These are not interchangeable — the inner hole must match the diameter of the shaft or spindle that passes through the plate, and the outer circle must fit within the recess or mounting pocket on your signal panel housing.

Important: Before ordering, measure both your existing plate's inner hole diameter and outer circle diameter with a caliper. Select the variant whose dimensions match. If you are unsure which variant you need, send us a photo of your existing plate alongside a ruler or caliper reading, and our team will help identify the correct option.

Typical Use Cases

• Signal panel assembly and repair: Replacement of worn or damaged twist-plates in electric carrier signal panel systems where rotational alignment is critical for proper signal transmission.
• Industrial machinery positioning: Any application requiring a locking twist-plate with a 16mm or 20mm bore for shaft or spindle retention at a specific angular position.
• Fixture and jig construction: Used as a rotational locking element in custom tooling, welding fixtures, and assembly jigs where a component must be rotated into position and then secured.
• Retrofit and maintenance: Direct replacement for damaged plates in existing carrier signal panel installations — no modification required when the correct variant is selected.

Frequently Asked Questions

I see three variants — which one fits my panel?

The three variants differ in inner hole and outer circle dimensions. Use a digital caliper to measure the bore of your existing plate (the hole through the center) and the overall outer diameter. Match these measurements to the variant listing. The "Inner hole 16mm, outer circle 50mm" variant has a 16mm bore and 50mm outer diameter. The "Inner hole 16mm, outer circle 58mm" variant has the same bore but a larger outer diameter for panels with a wider mounting pocket. The "Inner hole 20mm, outer diameter 58mm" variant is for larger shaft diameters.

What material is this twist-plate made from?

Verify the material from the product label or by inspecting the plate itself. Industrial twist-plates of this type are commonly manufactured from zinc-plated steel, stainless steel, or aluminum alloy depending on the application environment. If you require a specific material grade for corrosion resistance or electrical conductivity reasons, please contact us with your requirement before placing the order so we can confirm compatibility.

Can this plate be used in an outdoor signal panel?

This depends on the specific material and finish of the plate. If your signal panel is exposed to weather, you will want to confirm that the plate material has appropriate corrosion resistance. For outdoor installations, stainless steel or properly coated steel is preferred. Check the product label for material information, or contact our support team with your environmental conditions for a recommendation.

Do you sell the mating shaft or panel housing as well?

This listing is for the twist-plate only. The mating shaft, housing, and fasteners are separate components. If you need a complete signal panel assembly or additional related parts, send your equipment model number or a photo of the complete assembly to Moritta@KOEED.COM and we will check availability for the full set of components.
