Solid Shaft - Absolute Encoders
We stock two types of absolute encoders with solid shafts:
Italsensor TKC50 Absolute Single Turn Shaft Encoder- has a shaft rotational speed of 10.000 RPM to short cycle time; 6.000 RPM continuous. The shaft is made of stainless steel with a non-corroding aluminium flange and housing made from aluminium painted with inhibiting treatment 180° C. Specifications for shaft loading are axial: 200 N; radial 200 N. The rotational speed of the shaft is 10.000 RPM to short cycle time; 6.000 RPM continuous. It weighs 0.52 kg with a bearings life of 5 x 109 rev. min.
TKE45 Single Turn Absolute Encoder − as above, except its weight is 0.5 kg. Both encoders have Electrical Specifications giving STD codes: GRAY - BINARY − BCD, (although the TKE45 is analogue) an output frequency from 0 to up 20 kHz (L.S.B. without error) and protection against inversion of polarity (except 5Vcc).
Blind Shaft - Incremental Encoder
However, this type of speed and distance-measuring device does have one limitation. It will need to be equipped with a reference device which measures motion. These encoders function by generating an array of pulses while they are moving. As they move, they relay relative value data.
Absolute encoders are a little different. The provide output which details current positions of shafts, which puts them into the angle transducer category. This type of encoder comes with a separate digital output for every shaft position and this means that position data is accurate, even when power is interrupted. If power is lost, an encoder will offer accurate position data (or absolute data) as soon as the power goes back on.
Since this type of encoder provides the most reliable accuracy, it’s a fine choice for specific applications, including robots and machines which package items. When speed and distance data must be perfect, this encoder delivers.
Shaft Mounted - Tacho Generators
If the Tacho generator isn’t hooked up to load resistance, it’ll create voltage which is in approximate proportion to the speed of the shaft. A shaft-mounted Tacho Generator will be utilized in order to give a tachometer power, as well as to calculate the speed of engines and the rates of motion of other rotational mechanisms.
Different shaft styles are available, including hollow shaft, blind shaft and solid shaft products.
Tacho Generator Spares
Flexible couplings prevent over charge on the encoder shaft and so help prolong its life. Carbon brushes are used to transmit electrical currents within the tachogenerator. We supply a variety of brushes suitable for most tachgenerators. Measuring wheels are integral to the tachogenerator’s purpose of measuring shaft speed and producing the appropriate output voltage. We stock Hengstler measuring wheels according to 7 different profiles, in aluminium or plastic, with bores ranging from 4 mm to 10 mm and with or without rims. Friction wheels are the parts of the tachogeneator in contact with the movable surface. We supply 37 mm and 75 mm components which are compatible with Kone lifts. L brackets are used for base mounting. Our brackets are for use with the TK50 series encoder.
We’re happy to discuss your requirements to ensure that you get the parts to the specification that you need. Please don’t hesitate to contact us if you have any questions.
Drives, Motors, PLCs, HMIs, Fieldbus & Motion Control
We have completed many hundreds of projects, supplied thousands of parts and written countless line of software for installations in every continent of the world. We are proud of our ability to solve complex control and process issues and have often succeeded where even the original machinery builder has failed.

Coupling Components
We stock many different types and they can be broadly grouped into rigid and flexible shaft couplings. Rigid couplings are good for transmitting power where there is no misalignment between shafts. Flexible shaft couplings are required when there is a degree of misalignment or end movement or both.
