Pehu LMS Automatic Measuring System
The PEHU LMS30 to PEHU LMS80 are powered measuring system models which can be configured as either auto-measuring or auto-feeding systems. The operator enters the required stop positions into the NC control and the system automatically runs through the program until it is completed. Specific systems can be configured to work with saws, drills and steelworkers or punching machines.
The different models are configurable for varied capacities, and levels of automation.

PEHU LMS 60
The ideal length measuring system for positioning heavy to very heavy materials on a sawing machine. The material is positioned with a high degree of accuracy. The PEHU LMS 60 can be placed either to the left or to the right of the machine tool.
The PEHU LMS 60 length measuring system is extremely suitable for use in very heavy industry.
PEHU LMS 60 is an NC controlled system with a PEHU 112 – 5.0 Nm servo control. The PEHU LMS 60 is supplied as standard on a heavy UNP Frame, a hydraulic or electric folding stop and a user-friendly servo control. The stop is fitted with a sensor to switch the driven roller conveyor to a crawl speed, after which the material comes into contact with the stop in a controlled manner and stops the roller conveyor. A contact sensor has also been placed here that switches on a lamp on the stop carriage, so that you can see that it is lying against the stop. The PEHU LMS 60 length measuring system is easy to assemble and is separate from the roller conveyor (and can therefore be used anywhere!).
PEHU 112 – 5.0 Nm
The measuring system is equipped with the PEHU 112-5.0 Nm servo control . This is a very accurate 1-axis point-to-point control. The control is used as a stop.

PEHU Optional Extras
You can expand the PEHU Measuring Systems with additional options, as detailed below;
PEHU Extension
PEHU length measuring systems are extendable per meter. Extension consists of:
– Special angle line (powder coated Ral 7016)
– Linear rail
– Rack
– Cable duct + support + cover
– Cable carrier
PEHU Automatic Folding Stop
PEHU length measuring systems LMS15/30/45 are supplied as standard with a manually foldable stop. With the LMS15/30/45 you can opt for an extra support that lowers the stop in a controlled manner by means of a gas spring.
With the LMS 45 you can also opt for an electrically foldable stop. The stop is provided with a drive that you can operate from the control unit (pehu 112 cabinet). In some situations it is also possible to automatically fold up the stop during the retrack movement. The PEHU LMS 60/80 are equipped with a foldable stop as standard.
PEHU Material Stop Light
The PEHU stops can be equipped with a stop lamp, which lights up when material is against the stop. This is a handy aid for longer lengths.
PEHU Material Clamp
In order to prevent the material from rolling during pushing, PEHU has developed its own material clamp, which can clamp to any desired width by means of a fast sliding system. The pusher runs over a linear guide and is secured by means of a pin, after which it is tightened by hand. As an option, one can choose a pneumatic or hydraulic clamping.
PEHU Control Display in Arm
Control display is hung on the machine. Control cabinet with driver(s) is placed elsewhere. Maximum cable length between display and control cabinet is 8 meters. Control display hangs on a hinged part so that the reading angle is adjustable and will be easy to read for everyone.
PEHU Interconnection Kit
The kit is necessary if you are going to use a coupling between the push system and the processing machine. This ensures the communication between both systems. With this kit you can make a semi-automatic machine into a fully automatic machine. Or you can still feed a manually operated machine automatically without operating the control.
