Magnetic Pickup RS PRO 5 → 15 V dc, Магнитный датчик

Digital Magnetic Pick-Up

An ’active’ version of the standard type (Stock no. 304-166) but incorporating an IC to provide a digital output compatible with most logic systems
Requires a peripheral speed greater than 250mm per second to operate
Rise and fall times and amplitude of the output pulse are independent of the characteristics and speed of discontinuity
Output Characteristics: With no discontinuity moving in fromt of the pole piece, the output voltage will be less than 0.15V. For each discontinuity passing the pole piece, a positive pulse will be produced. To calculate the output pulse amplitude for various loads the following relationship may be used:

V_O = V_S x R_L / (R_L + 5000)
Where
V_O = Amplitude of output pulse (Volts)
V_S = Supply voltage (volts, dc)
R_L = Load impedance (ohms)
5000 = Approximate output impedance (ohms)

Caution

Not polarity protected, any momentary reversal of the supply voltage will destroy the device.

RS PRO Magnetic Pickup Sensor

Selecting Magnetic Pickup is essentially consisting of matching a pickup to gear (or other targets) to provide the right amount of input signal to operate at the desired minimum speed. Each type has its unique technical parameters; therefore, it is essential to choose suitable sensors at the right price and quality.
We are proudly introducing our own branded RS PRO Magneti Pickup Sensor, which is an "active" part of the standard type (RS PRO 304-166) but incorporating an IC to provide a digital output compatible with most logic systems.
Our Magnetic Pickups requires a peripheral speed greater than 250 mm per second to operate. Rise and fall times and Amplitude of the output pulse are independent of the characteristics and speed of discontinuity.

Output Characteristics: with no discontinuity moving in front of the pole piece, the output voltage will be less than 0.15V. For each discontinuity passing the pole piece, a positive pulse will be produced. To calculate the output pulse amplitude for various loads, the following relationship formula is here to help you achieve that.

VO = VS x RL / (RL + 5000)
Where
VO = Amplitude of output pulse (Volts)
VS = Supply voltage (volts, dc)
RL = Load impedance (ohms)
5000 = Approximate output impedance (ohms)

Magnetic Pickups

Miniature magnetic 'pickup' transducers are suitable for use in a wide range of sensing applications. Each device responds to the movement of ferrous parts past the pole at the end of the unit. They are used extensively in areas such as speed regulation of motors, when sensing, for example, the teeth on a gear wheel. However, magnetic pickups may be used to implement feedback and control functions in many fields. Automotive applications include crank angle sensing, ignition timing, anti-skid systems and diagnostics. Applications in the computer peripherals area encompass disc drives, line printers, card punches/readers and printer terminals. The diagrams indicate the two basic modes of using these components. Note especially their small size with their high signal output, enabling their deployment where many conventional sensors cannot be fitted. Fully encapsulated construction for reliable operation, but not intended for immersion in liquids.
