roller-feeder application page for connector pins
A roller feeder fits connector pins when fixed pitch, roll traction, mechanical synchronization, release geometry and contact-zone protection can be proven on the actual carrier strip.
Application-Specific Process Route
The route below shows the four checks for roller feeding in connector-pin stamping. For model limits by strip width, feed pitch and thickness, see our RFS roller feeder for power presses.
Inputs to Freeze Before Selection
- Connector-pin carrier drawing and plating/contact restrictions
- Fixed pitch, tolerance, roll diameter and drive/gear relationship
- Press cam/shaft interface and mechanical release geometry
- Strip thickness/width, strength and required traction
- Pilot holes, die correction and cumulative-pitch inspection
- Roll cleaning, backlash, lubrication and changeover plan

Engineering Decision and Verification Table
| Decision gate | How to verify | Required record |
|---|---|---|
| Contact map | Mark proposed roll paths on the carrier drawing | Approved contact-zone sheet |
| Pitch ratio | Calculate and measure one-cycle roll travel | Setup/pitch record |
| Release | Observe full strip freedom at pilot engagement | Timing evidence |
| Part sample | Inspect pin/carrier features and plating marks | First-off report |
Step-by-Step Verification
Work through the four gates below with the production drawing, material and real machine interface. Each gate produces a record that can be reviewed before production.

Failure Modes and Stop Conditions
- Roll-on-feature contact: Redesign contact zone before running plated terminals
- Backlash drift: Stop on cumulative-pitch trend beyond the approved limit
- Release wear: Do not compensate worn geometry with excess roll pressure
Acceptance Record
Freeze the released drawing and material revision, machine configuration, interface list, recipe, sample plan and measuring method. Record exceptions and the safe restart route, and identify the tested configuration in every reported result.
