PEHU LMS 30 Automatic Measuring System with Digital Readout
The PEHU LMS30 is a versatile powered measuring system, designed for both automatic measuring and feeding. Operators simply enter the required stop positions into the NC control, and the system executes the programme with precision and ease. It can be configured to work with a wide range of machinery, including saws, drills, punching machines, and steelworkers.
For larger or more demanding applications, the LMS45, LMS60, and LMS80 models offer increased capacity and enhanced automation options. The range also includes the manual LMS15, which can be upgraded with a controller for automatic measuring – providing a flexible entry point into automation.

Frequently Asked Questions
What is the PEHU LMS 30 automatic measuring system designed to do?
The PEHU LMS 30 uses a servo-controlled stop carriage to position material accurately for repeated sawing, drilling or punching operations. Depending on the controller and integration, it can be configured for semi-automatic measuring or fully automatic positioning and feeding.
What working length is available on the PEHU LMS 30?
The published LMS30-04 has a 4,000mm base length and approximately 3,600mm working length. Extension sections are available in 1m increments for longer measuring requirements.
What positioning accuracy does the PEHU LMS 30 offer?
Selmach lists ±0.1mm positioning accuracy for the LMS 30. This refers to the positioning system; finished-part tolerances also depend on the cutting or processing machine and material handling.
What is the difference between the LMS 30 semi-automatic and fully automatic controls?
The LMS30-04 with PEHU 112S 3.3Nm control is listed as semi-automatic stroke control, while the PEHU 112 3.3Nm configuration is listed as fully automatic. Confirm whether you need a stop-only arrangement or a linked feeding sequence before ordering.
Can the PEHU LMS 30 work with a bandsaw or circular saw?
Yes. Selmach describes the LMS 30 as suitable for integration with saws and other processing machines. Compatibility depends on the saw, conveyor, safety arrangement and any interconnection kit required for the chosen automation level.
Does the PEHU LMS 30 include roller track?
Roller track is available separately. The LMS 30 can be fitted to a suitable existing conveyor, or Selmach can help specify an infeed or outfeed track to match the machine and material being handled.
What should operators check to keep the LMS 30 accurate?
Keep the linear guide, rack and stop face free from swarf and damage; inspect the travel path and check the stop position against a known dimension. Follow PEHU guidance for servo faults, calibration and maintenance.
Is a Selmach Service Plan available for the PEHU LMS 30?
Ask Selmach about servicing and whether the LMS 30 and its associated processing machine can be covered under an appropriate Service Plan. Confirm that the quotation includes the measuring system, controller and any integrated safety equipment.
