1054_0B Phidget FrequencyCounter


GTIN 1234567554



This 1054_0B Phidget FrequencyCounter is designed to count events from an analog signal over time and calculate a frequency from it. The product can count a logic level or signal centered around zero volts. Signals with a different ground can be counted, provided they are within the common mode range (±10V).

The Frequency Counter can also power small devices, such as Hall effect, flow rate sensors, tachometers, and other sensors.

This Frequency Counter contains two channels to sense two different inputs. Each channel has two different circuits to sense for logic level-frequencies or zero-centered frequencies. The measurable frequency is accurate to 0.25% up to 1MHz. The Frequency Counter may measure frequencies past 1 Mhz, but the input voltage specifications will not hold.

This Frequency Counter can measure frequencies down to ~ 0.01Hz. However the response time of these measurements is directly related to the frequency, thus it could take 1 or 2 periods(100-200s) to detect the input frequency.

Note: The 1054_0B is identical to the 1054_0, except that you have the option of whether you want to include the USB cable.

1054_0B Phidget FrequencyCounter comes Packaged with

  • A Hardware mounting kit (4 nuts and bolts (M3), 4 plastic spacers)
