Crimp Applicator Parts: Shut Height, Stroke and Tooling Fit
Identify crimp applicator parts and separate shut height, press stroke and finished crimp height before reusing tooling or ordering a bench press.

Identify crimp applicator parts by their function and the applicator’s parts drawing, then check the press interface before reusing the tooling. Shut height, press stroke and finished crimp height describe different dimensions. A matching force rating or a similar-looking mounting plate does not prove that an existing applicator will operate correctly on another press.
Separate the press from the applicator
The press supplies the motion and force. The applicator positions the terminal and carries the tooling that forms the connection. A problem visible in the finished crimp can originate in either system, so record both identities when asking for a replacement part or a new press quotation.
Include the terminal part reference, strip sample, conductor construction and insulation diameter. The wire’s nominal cross-section alone does not identify the terminal geometry, carrier pitch or insulation-support requirements. Our terminal crimping machine guide covers selecting the overall processing route.
Use part names to describe the job
The following functional names help identify a component. The actual drawing controls its name, position and replacement number; different applicators do not necessarily contain identical parts.
| Component or group | Typical function | Information to send |
|---|---|---|
| Ram connection and base plate | Locate the applicator in the press and transmit motion | Mounting drawing and reference dimensions |
| Conductor punch and anvil | Form the conductor crimp | Terminal reference and exact tooling part numbers |
| Insulation punch and anvil | Form the terminal’s insulation support | Insulation diameter and required profile |
| Terminal track and feed mechanism | Present the next terminal at the tooling | Strip pitch, feed direction and carrier sample |
| Cut-off tooling | Separate the terminal from its carrier | Carrier geometry and allowable cut-off condition |
| Wire stop | Provide a reference for wire placement where fitted | Strip length and wire-position requirement |
The Molex FA2 manual distinguishes general component identification from the terminal-specific tooling document. Use that same distinction when ordering: a recognizable part name is not yet a replacement specification.
Check three dimensions independently
Shut height is the distance between the specified press mounting references at the closed position. It is an interface requirement, measured using the appropriate procedure and gauge. Use the target stated for the exact press/applicator combination; there is no single value that should be applied to every system.
Stroke describes ram travel. Adequate travel must work with the applicator’s feeding sequence, opening and operator or wire-transfer clearance. Two presses can have equal force and different strokes. Increasing stroke is not a substitute for confirming shut height.
Crimp height is a dimension of the formed terminal at the specified measuring location. It is checked against the connection specification after the press and tooling have been set up correctly. Do not treat a controller field, adjustment scale or shut-height reading as a measurement of the finished connection.
Panduit’s applicator instructions include a system-specific shut-height check. Such procedures belong to their stated equipment and tooling; they are not generic adjustment instructions for another press.
Make a compatibility record before the trial
Keep the three dimensions in separate fields. Include the press and applicator identities and their drawings so that each value refers to the same mounting surfaces and tooling configuration.
| Check | Information to provide | What must be confirmed |
|---|---|---|
| Base and ram connection | Dimensioned mounting drawing, locating features and connection details | The applicator seats and connects correctly to the press |
| Shut height | Required value, reference surfaces and the specified measuring procedure | The closed press-to-tooling interface matches the applicator requirement |
| Ram stroke | Required travel and the applicator’s feed/opening sequence | Travel permits feeding, opening and wire handling; it is not a crimp-height setting |
| Finished crimp | Terminal reference, wire construction, insulation diameter and specified crimp-height target | The actual connection meets its specification after mechanical setup |
| Feed path and installation | Strip pitch and feed direction; reel, scrap and wire-handling space; utilities and guarding | The matched tooling can feed and operate in the intended layout |
Use photographs to show the installation, together with dimensioned drawings. Photographs alone cannot establish shut height or the correct replacement tooling.
Our WM-3102S servo bench press lists 20 kN force and a 30 mm stroke, with 40 mm available by customization. We match the applicator to the terminal strip and production wire. These listed figures do not claim compatibility with every applicator or with the example equipment in the cited manuals.
Before installation or adjustment, follow the press and applicator manuals, including isolation and the approved setup procedure. Compatibility checks should resolve mechanical interference before production operation, not by forcing the tooling through a powered cycle.
Approve the connection after approving the fit
Use first-piece inspection to check wire position, conductor and insulation crimp dimensions, carrier cut-off and the specified appearance. Add pull testing or cross-section inspection where the connection requirements call for them. A mechanically compatible tool can still produce an unacceptable connection with the wrong terminal, wire or setup.
For diagnosis, retain the rejected piece, terminal strip, wire lot and setup record. Follow our crimp defect guide and inspection-method comparison to choose the check that answers the observed problem.
Send the press and applicator drawings, terminal strip and wire samples, together with the required finished-crimp dimensions. We will check the mounting, shut height and stroke separately, confirm a matched press/tooling configuration, and demonstrate the connection against the acceptance requirements agreed for your job.
Questions engineers ask
Are shut height and crimp height the same measurement?
No. Shut height describes the closed press-to-tooling interface at specified reference surfaces. Crimp height is measured on the formed terminal. Both must meet the requirements of the matched press, applicator and connection.
Does a matching press tonnage prove applicator compatibility?
No. Check mounting, ram connection, shut height, stroke, feed arrangement, clearance and the terminal-specific tooling. Force rating alone cannot establish those interfaces.
Can we order a replacement punch from a photograph?
Use the applicator identity and its parts drawing, together with the terminal and wire specification. A photograph helps locate the component but does not establish the correct replacement geometry or part number.
