AT- Economical Tubular Housing Magnet constrictive technology at a potentiometer price, Accurate Linear Position Measurement: The Micro pulse® AT is a superior alternative to traditional low-cost linear feedback devices such as linear potentiometers (pots). Balluff designed the Micropulse AT in a modular fashion to simplify manufacturing and reduce component costs to be competitive with these devices.
The main advantage of the Micropulse AT is the non-contact, wear-free nonrestrictive sensing principle. Linear potentiometers, by contrast, are electro-mechanical devices that utilize a moving wiper contact riding along a resistive element. Both the wiper contact and the resistive element are subject to wear from repeated operation and continuous machine vibration. Abrasive contaminants are able to enter the potentiometer housing through the mechanical seals, further accelerating wear leading to erratic position signals.
With no moving parts, the Micropulse AT is impervious to environmental contamination such as dust and grit. It is also shock and vibration rated for use in demanding industrial applications. The convenient M12 connector assures easy installation and quick replacement without the need to remove and reinstall hardwired cabling.
The round housing of the Micropulse AT allows the unit to be rotated to sense the position magnet in multiple directions, enhancing installation flexibility. The position magnet is a floating design, meaning no mechanical linkage is required, saving cost and reducing installation complexity. Linkage is eliminated as a source of backlash error. No mechanical linkage also eliminates over-stroking as a potential source of sensor breakage and production downtime.
