Sin / Cos Rotary Encoders - S21

REQUEST A QUOTE

Accurate sinewave rotary encoders by HENGSTLER are a preferred choice in drives with high dynamics thanks to their low harmonic distortion. They have excellent immunity to interference and high functional dependability due to control and system monitoring. The broad working temperature range means the motor can be used to capacity more effectively.

• Broad range of working temperature, -15 to +120°C, Optimum exploitation of motor capacity
• Unequalled bandwidth of 500 kHz at full signal quality, Peak speeds and reduction in unproductive downtime
• Excellent immunity to interference (EN61000-4-4 severity 4)
• High functional dependability through signal control and system monitoring (undervoltage, contamination, Disc breakage,
  End of LED life-time)
• High signal quality through control and error compensation

MEASURING WHEELS
General information

In order to prevent the result being distorted when the shaft encoder is driven by a measuring wheel make sure that the slip is as small as possible. When selecting the tread (surface), take into account the structure, stretchability, thickness, and resistance to being carried along of the material being measured. The slip is also affected by the width of the measuring wheel, the contact pressure, the tension in the material being measured, and the arc of contact. The arc of contact should be as large as possible. The wheel bodies are made of cast aluminium or plastic (as marked). The position of the measuring wheel should be chosen so that the direction of movement of the material is away from the shaft encoder’s bearing point.
