NMW 2006: Heidenhain updates explosion-proof encoder


Rosemont, IL (Chicago suburb) —Control equipment and devices need to upgrade their built-in toughness to be able to keep pace with the harsh application environments they serve. A case in point is the increasing ruggedness exhibited by feedback devices.

Among products displayed by Heidenhain Corp. at National Manufacturing Week (NMW) shows, March 21-23, was an explosion-proof version of its rotary encoder—ROD 420—which embodies a standard 58-mm (2.28 in.) diameter housing, compact total length of 83 mm, and line counts from 250 to 5,000. Thomas C. Wyatt, product manager for drives and automation at Heidenhain, told Control Engineering that typical applications for ROD 420 rotary encoder are potentially explosive mists found around spray-painting lines and printing machines.

An updated version of an earlier Heidenhain encoder, ROD 420 limits maximum allowable surface temperatures to 120 °C (248 °F). A temperature sensor incorporated into the unit monitors this condition and will trigger a warning signal to alert the user of the impending critical temperature so that the system can be returned to a safe operating state.

The company is the North American subsidiary of Dr. Johannes Heidenhain GmbH of Germany—a leading manufacturer of precision measurement and control equipment
