We, Proximon serves as the authorized distributing point
for a well known European brand Hohner, Italy. The products offered by us
involved Incremental (Shaft / Hollow Shaft ) and Absolute Encoders. These
encoders are used in AC drive feedback, door closing devices, x/y
indication, ultrasonic welding and robotics.
Absolute shaft encoders assign a unique, digitally
encoded signal to each individual measured increment. Single turn as well as
multi - turn types are available.
The special feature of absolute shaft encoder is that they assign a
unique, digitally encoded signal to each individual measured
increment. The method of transducing in these absolute shaft encoders
prevents erroneous readings whether by a power failure, or by a transient
malfunction. After the absolute shaft encoders are switched on again, or
power is restored, the position can be read out. Absolute shaft encoders are
not necessary to move to a reference position, as it is for shaft encoders
of the incremental type.
Example of application for absolute shaft encoder
- Overhead support robots
- Ventilation flaps
- Spinning machines
- Conveyor belts
- Cam controllers
- Injection moulding machines
- Packaging machinery
- Extruders
- Folding machines
- Printing machines
- High lift storage systems
- Stamping machines
Absolute shaft encoders generate a signal for each
incremental change in position. Encoder diameter ranges from 30 to 76mm with
push - pull / push - pull complimentary/ line driver (RS422) outputs are
available.
With the optical transformation, a line coded dise made of metal plastic or
glass and positioned on a rotary bearing interrupts the infrared light ray
emitted by gallium arsenide sender diode. The number of lines determines the
resolution, i.e. the measuring point within a revolution. The interruptions
of the light ray are sensed by the receptor element and electronically
processed. The information is then made available as a rectangular signal at
the encoder output.
Incremental Encoder (Shaft/ Hollow Shaft)
Incremental shaft encoders generates a signal for each
incremental change in position. Diameter of incremental shaft encoders ahve
a range from 30 to 76mm with push - pull / push -pull complimentary/ line
driver (RS422) outputs are available.

dise made of metal plastic or glass and positioned on a rotary bearing
interrupts the infrared light ray emitted by gallium arsenide sender diode.
The number of lines in these incremental encoder determines the resolution,
i.e. the measuring point within a revolution. The interruptions of the light

Examples for typical applications of incremental encoder
- Franking machines
- Door closing devices for trains
- Desktop robots
- Lens grinding machines
- Plotters
- Testing machines for optical waveguides
- Scattering machines
- Tampon printing machines
- Ultrasonic welding
- Screwing machines
- Labellings machines
- X/Y indication
- Analysis devices
- Drilling machines
- Mixing machines
PRiCO (Programmable Intelligent Counter) provides a very
cost - effective and reliable solution to many complex counting
requirements. What sets Programmable Intelligent Counter apart from the
conventional counters, is its programmable multifunction facet.
