Pneumatic Timers & Counters

Kuhnke’s wide selection of Counters and Timers provide easy solutions for constructing pneumatic logic systems. Counters are available with 4 to 8 digit readouts, panel or base mounting with several options to suit the application. Five versions of pneumatic timers with ranges from .1 second to 100 hours with a variety of valve and mounting options provide the most complete product line available in the industry.

Counters are constructed with durable molded bodies. White digits on black background make units easy to read. Units are available with or without manual resets and a variety of options. A special type allows the counter to be reset by a pneumatic pulse in addition to a manual reset button. A predetermining counter includes an output valve to stop production when the count is reached.

Timers depending on design, are constructed of molded bodies usually with aluminum bases to provide sturdy fitting connection points. Timers are available in on delay or off delay versions and incorporate a 3 or 4 way output valve.

Typical timing circuits are available on this site to assist in designing easy installations.

Panel Mounted Panel Mounted Pneumatic Counter
The pneumatic counter can be used as an event, part or lot counter. The counter registers pneumatic impulses on a 6 digit display. Totalizer operates with impulse pressure between 30 and 115 PSI. The counter can be reset either manually via a reset button, or by a pneumatic signal to a specially provided port.

These pneumatic totalizers can be used as an event, part or lot counter. The counter registers pneumatic impulses on 4, 6 or 8 digit displays. Standard units operate with impulse pressures between 25 and 100 PSI. Low pressure models operate between 7.5 and 30 PSI. A variety of options include panel mounting with screws or mounting clips and surface mount with base or rear stud. The counters are available with or without manual reset.

Miniture Panel Mounted Timer Miniature Panel Mounted Timer
The Mini-timer is an adjustable panel mounted time delay device (normally closed valve). Timing is set by adjusting the front dial. The timer is equipped with 2 vertical scales that indicate the set time and the time remaining in the cycle(countdown time).

Rear Mounted - Set-it, Forget-it Timer Rear Mounted - Set-it, Forget-it Timer
The Series 51 timer is an adjustable precise time delay control device. The timer is available with either an on delay (NC) or off delay (NO) 3 way built-in valve. It is designed for mounting along with valves or other logic devices and is available with 10-32 (M5) bottom ports, or1/8" NPT side ports. Bottom ported timers can also be panel mounted using (2) threaded M3 inserts on the topcover.

Panel or Subplate timer Panel or Subplate Mounted Pneumatic Timer
The Type PMT timer is an adjustable precise time delay control device. The timer is available with an on delay (NC) output. Timing operation is dependent upon the input of a separate control signal which starts the timing sequence by setting a vacuum within the timer. Using atmospheric pressure (independent of line pressure), the timer begins the preset timing cycle. At the end of the cycle an internal 3 way valve is switched providing an output. The timer resets automatically after removal of the control signal.

Panel or Rear Mounted Pneumatic Timer Panel or Rear Mounted Pneumatic Timer
The PT series timer combines a pneumatic timing mechanism with a floating spool valve assembly to provide a wide range of adjustable time control for fluid power systems. The timing assembly, which operates independently of the control pressure, is available in nine different ranges from one tenth of a second to 60 minutes, adjustable by means of a time-calibrated dial. Timing action is initiated by a motor diaphragm operatedby a control pressure of from 5 to 140 PSIG.

Panel mounted timer Panel Mounted Pneumatic Timer
The 54 Series timer is a totally pneumatic device with +/-1% repeatability. Timing is fully adjustable throughout the timing range by a knob on the front dial face. The standard timer is equipped with a special 4 way valve which provides for on or off delay timing (depending on plumbing connections). The front dial displays set time and the time remaining in the cycle.
