EP - REP Incremental Rotary Encoder

Programmable incremental encoders series


EP/REP - Programmable Magnetic Incremental Encoders

  • Pulses per revolution: 8 - 2048
  • Pulse code: Incremental
  • Output signals: push/pull or line driver
  • Shaft Ø: 6, 8, 9.52 or 10 mm
  • Protection degree: IP64 (optional IP65)
  • Operating temp.: 0 ÷ 70°C

Features EP/REP

  • Magnetic incremental encoders
  • Programmable ppr number
  • Zero pulse
  • Several configurations available
  • Accurate, strong and reliable

Incremental encoders EP/REP ppr no. ranges from 8 to 2048. The ppr no. is easily set by the user directly via PC; the programming kit supplied with the encoder includes the USB cable ended with the encoder connector, and the CD with the programming software.

EP/REP operate according to the magnetic principle, and offer excellent performances in terms of resistance to vibrations and shocks, acceleration, speed and protection.
The different mechanical versions can meet every type of application requirement; each mechanical type is available with ABS plastic case – series EP with push-pull output – or metal case – series REP with line driver output.

Type EP

  • ABS plastic case
  • Push-pull electronic output
  • 7-pin MS connector axial or radial outlet

Type REP

  • Aluminium case
  • 5 Vdc or 5/28 Vdc line-driver output
  • 12-pin Connei connector axial or radial outlet
