PU-2E

description

• 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 V 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.

features

• Mounts directly on shaft being monitored using single 10-32 screw
• Maximum speed: 5,000 rpm or 50,000 pulses per minute
• Supply voltage +4.5 VDC to +24 VDC
• NPN output signal with built-in pull-up resistor, square wave output
• signal voltage equals supply voltage, +5 VDC to 24 VDC supply voltage
• Current sink: 50 mA absolute maximum
• Operating temperature: -10 °C to +45 °C
• Stainless steel ball bearing
• Compact housing of molded Santoprene® plastic rubber
• Output cable: 6' rubber jacketed, three-wire 18 AWG conductors

includes

• Quadrature model to monitor both motor speed and direction by providing two square wave output signals 81° out-of-phase

caution

• Any sliding spool valve, if held for long periods of time, may stick and not spring return due to fluid residue formation and therefore should be cycled periodically to prevent this from happening
