MAGNETIC PICK-UP KITS
Magnetic pick-ups (digital velocity transducers) are used to provide shaft speed information for digital rate indicators (VT8 Series)
AND DIGITAL VELOCITY SERVOS $,#
Magnetic pick-ups are generally used in high speed shaft applications where the pick-up is directly monitoring motor shaft speed.

PICK-UP
KITS
The PU-E Series pick-up is an economical and reliable way to monitor motor speed. Its patented
design provides ease of installation in otherwise difficult to reach areas.
The PU-E pick-up operates at a 5 to 24 volt level producing a sharp square wave output, which
may be fed into Dart’s field programmable tachometer, closed-loop control, counter, or most other
digital devices.
The PU-E pick-up series also includes a quadrature model to monitor both motor speed and direction
by providing two square wave output signals approximately 90° out-of-phase.
