Mechatronics Test Equipment

Couplings for encoders & light duty applications. They are flexible in lateral and angular position movement yet torsionally stiff in rotary motion. The shaft coupling series psk are spiral versions, which are comparatively `softer’ in axial and angular movements as compared to series ppk in straight slit versions, both are torsionally rigid. They are used for even the most precision shaft encoders to transmit position information of very high resolution – e. G. 131072 steps per turn. Also used as stepper motor drives, tachogenerators and all rotary precision position transmitters.

features :-

• transmit with precision, rotary digital or analog information. • available in bore sizes from 4 to 15mm
• suitable as shaft diameter converter
• protect shaft driven precision instruments like encoders
• zero back-lash
• permit slight axial, lateral and angular movements
• precise concentric integral clamping
• light weight
• compact space saving.

must for an enquiry! – quantity required – bore dimensions d1 and d2 – type of coupling – whether spiral type psk or ppk in straight slit version – application on machine.

Digital Signal Transducers For Encoders

The output signals of encoders are interpreted in the form of position shown digitally and outputted in analog form or RS 485. The digital transducer EDA-201 can accept signals from absolute single or multiturn encoders in synchronous serial interface form or parallel binary or grey form. The digital transducer EDA-201 is used in industry or machines to count length of web or dosing applications. It can be scaled to give meaningful reading corresponding to rotary or linear position e.g. degree, mm, etc. Additionally it gives analog signal. It can also accept pulses(square wave)from incremental encoders. Another digital transducer(Pulse Tachometer)PST-201 is made to interpret speed, scale it to desired parameters e.g. rpm, M/min, etc. display and give 4-20mA output. Other blind transducers like signal converters SPG-3 convert SSI to parallel outputs for absolute encoders. Yet another range of interface transducers e.g. INTC5, INTC50 are meant for incremental encoders for compatibility to users input.

Features:-

• Economical SSI to Binary/ Grey converter SPG-3 for 24 bits
• Scalable EDA-201 converts SSI to Parallel output or RS485 from single & Multiturn absolute encoders.
• Detachable, programming unit,locking the Set data
• PST-201 to indicate speed digitally – scalable
• Gives 4-20mA scalable output
• Two programmable Set value outputs.
• Interface cards to convert six channel to 3 channel clear pulses
• Other interface modules for long cable lines upto 500 meters.

MUST FOR AN ENQUIRY! – Quantity required – Digital speed or Position indicator – Source of pulses e.g. Absolute or Incremental encoder, etc. – Analog or digital output and its form – Input circuits where interface transducers required – Application for compatibility.
