Product Description:

The 0727225-001 counter is used to record mechanical processes including repetitive process steps where no power is available. It belongs to Danaher and it constructs reliable designs to ensure long term performance in various engineering and technology sectors.

The 0727225-001 counter is a small ratchet drive reset counter. It has a drive system based on a ratchet mechanism that moves forward each time there is a mechanical movement of the input. The display is manually reset by use of the side lever all zeros are brought back to zero at once. The counting can only be in one direction and therefore its operation is repetitive in press cycles or machine actions like rotary machines. It is not a bidirectional input which ensures decreased complexity and less possibility of wrong readings. It can be clocked at a maximum of 600 counts per minute or fast enough to serve most light to medium industrial processes requiring a continuous counting operation. Its base screw holes are used to mount the device and offer a fixed attachment to both flat surfaces or around panel mounts. The housing has mounting holes that can be utilized into usual industrial automation areas.

The 0727225-001 counter does not need any electrical connection as it works on a purely mechanical basis. It works by moving its indicator with mechanical action normally by means of a ratcheting lever. A single exertion produced by the lever causes it to count one unit. It is a five-digit mechanical type display that counts up and registers the values between 5 zeros and 5 nines. The numbers are all printed clearly on screen to be easily visible within a normal indoor light environment.

Frequently Asked Questions about 0727225-001:

Q: Why does the 0727225-001 not require electrical input for operation?

A: It operates purely through mechanical motion, removing the need for wiring or power sources, making it suitable for remote or unpowered systems.

Q: When should the reset function be used on the 0727225-001 counter?

A: The reset lever should be used after each batch or process cycle to initialize the counter for a new sequence.

Q: How does the 0727225-001 enhance manual machinery monitoring?

A: It provides a tangible, visible count of operations, eliminating guesswork in mechanical task repetition or shift-wise tracking.

Q: Which component in the 0727225-001 ensures accurate digit advancement?

A: The internal ratchet pawl assembly synchronizes lever motion with wheel increment, ensuring consistent count per mechanical stroke.

Q: What digit range is available in the 0727225-001 display?

A: It features a 5-digit display, allowing for tracking up to 99,999 cycles or operations before reset is required.


Internal Product Review

  • ‘‘The 0727225-001 counter from Danaher, series timers and controllers is reliable for industrial stroke counting. Its unidirectional ratchet drive and 600-count-per-minute speed support consistent results. It has sturdy base mount and manual reset which are ideal for setups needing precise, non-electric counters.’’
