Portescap Encoders

Supplier: M Rutty & Co

Portescap Encoders include the DC tachmoeter: V* with ironless rotor and commutation system made of precious metals. The Magnetic encloder: P* Encoder integrated in tne motor. Position monitored by Hall sensors. Optical encoder" P+V*. Photatransistors in push-pull. Stand-by mode. Mask integrated on recivers.

Price Guide: POA

22mm optical encoders (up to 512 ppr)

  • Provide controlled precision movements when paired with specialty motors
  • Provide tachogenerators and a combination of motor-tacho units
  • Compact design
  • Magnetic encoders integrated into or adapted onto specialty motors are available.

The DC tachometer: V* delivers a continuous signal, adds neglectable inertia and constant signal quality.

The DC tachometer V* has easy control even at very low speeds, little additional load for the motor and low sensitivity to hostile environments.

Magnetic encoder: P* - simple construction, compact design. Two output channels.

Its advantages are insensitive to hostile environments, negligible increase in length of the unit. Very low current consumption. High reliability and long life.

Optical encoder: P+V* - high resolution, two channels plus home position.
Signal level very stable, cuts LED supply at stall. No thermal drift.

Very precise positioning, facilitates counting the number of revolutions
No phenomenon of aging. Lower consumption, lower temperature rise.
Insensitive to temperatures, small dimensions.
