Product Description:

The 0728735-001 Counter is the product of Danaher that is renowned for precision engineering and dependable industrial automation solutions. This module's outer housing and interior mechanisms are crafted from rugged, molded materials that shield it from knock, vibrations and the wear that comes from while using it for longer periods.

The 0728735-001 counter is designed to be secured by its foundation that allows it to be fastened firmly to a flat surface. Its readout characters appear in a light hue against a dark backdrop creating a strong visual contrast. In this module, the total can be returned to its starting point by physically turning a built in dial and requires no electrical control. This module's housing is produced from a nylon resin with glass fibers and its rotating spindle is made from stainless steel. It has a low mass of 2.4 oz that makes it light enough for simple handling, transport or installation. It can work well in humid or harsh environments as its central rotating rod is designed from corrosion resistant steel alloy. It does not require periodic greasing or oiling and the highest torque it can be resistant without motion is three ounces inches.

This 0728735-001 counter is designed to deliver precise readings with minimal vibration and its robust build supports long service life. It is able to turn at a rate of up to one thousand complete revolutions per minute. The module's display is small but still legible as each numeral it displays has a height of just under two tenths of an inch and a width of roughly one tenth of an inch. Its materials and assembly prevent fine particles and environmental moisture from degrading performance.

Frequently Asked Questions about 0728735-001:

Q: How is the 0728735-001 Counter best secured during installation?

A: It mounts via its base, so a flat, rigid surface ensures alignment and stability. Improper mounting can cause vibration, reducing accuracy over time.

Q: What effect does the display’s contrast have on usability?

A: The high-contrast figures improve legibility in dim light or from awkward viewing angles. This reduces operator error when reading counts quickly.

Q: Is this counter suitable for high-speed drive shafts?

A: It can handle up to 1000 RPM without performance loss. Exceeding this may cause mechanical wear and counting inaccuracies.

Q: How does the compact figure size affect reading from a distance?

A: Smaller numerals are legible up close but harder to read beyond a few feet. Positioning the counter at eye level improves visibility.

Q: What is the practical implication of its low torque resistance?

A: The drive shaft will rotate with minimal force, reducing wear on the driving mechanism. Overloading beyond its static torque rating risks mechanical damage.
