DART CONTROLS PU-E SERIES SPEED PICKUP PU-40P

DART CONTROLS PU-E SERIES SPEED PICKUP is an economical and reliable way to monitor motor speed. Its unique design provides ease of installation to otherwise difficult to reach areas.  Installation is simple - drill and tap a target shaft and you're done. The PU-E pickup 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 any other digital device. Completely self contained, the PU-E series eliminates the alignment hassle found with other devices. An excellent 'Motor Not Running' feedback device to PLC/SCADA systems. For indoor use only.

Features:

• Single screw installation - no alignment needed
• For shaft speeds up to 5000RPM
• 6' cable provided with rubber jacket (may be extended up to 300')
• Supply Voltage: +5 to +24VDC
• PNP output
• Ambient temperature range: -40°C to +100ºC
• Santoprene injection molded head
• Rated for indoor industrial applications

Application Notes:

• If installing the unit on a motor purchased from Dart, the motor shaft is already drilled and tapped.  If the motor is fan-cooled (TENV), remove the plug in the center of the fan guard before installing the pickup.  Otherwise, damage to the pickup may occur.
• No other screws are necessary, as the cord will keep the unit from rotating.
• The PU gives a high signal when the North Pole in the magnet crosses the hall-effect transistor. The signal is switched off when the South Pole crosses the hall-effect transistor. The result is a square wave whose frequency is proportional to the speed of the shaft that the PU is mounted on. The number of North/South Pole pairs directly affects the output.
