SPM - Optical incremental encoder

Reliable optical incremental encoders with increased (SPM) and reduced torque (SPNTM) with good adaptability to the application.

Special Features

  • Up to 1024 pulses / 360° (max. 5000 ppr)
  • 2 channels + index
  • TTL or line driver output
  • Shaft side up to IP55M / IP66S
  • Installation depth 18,7 mm
  • Option connector with lock
  • Made in Germany

The optical incremental encoders SPM (increased torque) and SPNTM (reduced torque) are ideal for applications that require high durability and adaptability of the sensor.

The optical incremental encoders of the series SPM (increased torque, in IP55 on shaft side) and SPNTM (reduced torque, in IP40 on the shaft side) are characterized by their reliability and long lifespan of more than 100 million shaft movements. The sensor with Ø6 mm or Ø6,35 mm (1/4 ") shaft is fixed by means of central thread. Depending on the version, a resolution of 50..1024 pulses per revolution (360 °) is available as TTL or Line Driver output signal. Upon request further resolutions such as e.g. 1250/2000/2048/2500/4000/4096 and 5000 ppr are realized. The incremental encoder detects angles contactless and has a high-quality metal sleeve bearing. The SPM is particularly a encoder for a precise manual input of values. A typical application of the SPNTM is the measurement of values. A comfortable choice of electrical interfaces as standard, such as soldering / plug-in contacts (TTL), optional connector with lock (TTL or Linedriver), complete the profile.
