Extension Rod L 100 mm – 4 mm Measuring Pin for Dial Indicators (Käfer)

The Extension Rod L 100 mm is an accessory piece that extends the reach of dial indicators, providing a 4 mm measuring pin for precise contact measurement in confined or recessed areas.

• Extension rod 100 mm length
• Measuring pin diameter 4 mm
• Compatible with dial indicators

Reach recessed features with maintained measurement quality

The 100 mm extension increases the working range of a dial indicator while preserving the contact geometry required for accurate readings. By adding a measured length between the indicator spindle and the contact point, the accessory enables inspections in blind holes, deep grooves and assemblies where direct access is restricted. The 4 mm pin diameter provides a standard contact footprint that is widely accepted across gauge tips and probes, supporting repeatable positioning and stable contact during measurement cycles.

Simple integration into metrology workflows

Designed as an accessory for dial indicators, this extension piece allows straightforward assembly without complex adapters. The geometry is intended to maintain alignment and reduce lateral deflection during contact, which supports consistent results in production checks and setup routines. For workshop environments where tool changeover speed matters, the plug-and-play nature of the extension reduces downtime and supports faster part inspection sequences, contributing directly to operational efficiency and throughput.

Reliability and confidence for routine inspection tasks

Supplied as a single unit and matching standard metrology practice, the extension rod supports a disciplined inspection regime by enabling measurements that would otherwise require repositioning parts or instruments. The clear specification of 100 mm length and 4 mm measuring pin diameter makes it simple to document measurement setups and trace inspection steps. When combined with established dial indicators, the accessory helps maintain traceability and repeatability — key factors for quality control in workshops and small production lines.

FAQ

What is the primary purpose of this extension rod?
The extension rod extends the reach of a dial indicator so that contact measurements can be taken in recessed or hard-to-access areas without repositioning the workpiece.

Which indicators are compatible with this accessory?
Compatibility is with standard dial indicators that accept a 4 mm contact pin interface; the Käfer extension rod matches common spindle and tip geometries used in workshop metrology.

How does the 4 mm measuring pin influence measurement behaviour?
A 4 mm pin provides a stable contact surface that balances access and repeatability; the specified diameter supports consistent contact force distribution for reliable readings with the appropriate gauge tip.

Can the extension rod be used for traceable inspection procedures?
Yes, the clear specification of 100 mm length and 4 mm pin diameter allows documentation within inspection plans and supports repeatable setups; the SKU 4000851692NW can be recorded in measurement records for traceability.
