RS, a high-service global product and service solutions provider for industrial customers, has officially announced the availability of Dynapar’s extensive range of incremental encoders, including its heavy-duty HS35R and smart HS35iQ hollow-shaft optical encoders.
To understand the significance of such a development, we must take into account how incremental encoders calculate the current position, velocity, and acceleration of objects in motion, and as a result, are critical for improving operator and equipment safety, monitoring physical loads, and supporting Industry 4.0 initiatives, including flexible packaging and predictive maintenance.
Against that, Dynapar’s HS35R heavy-duty, hollow-shaft optical incremental encoders arrive on the scene as ruggedized versions of its original vector-duty hollow-shaft encoders engineered to increase reliability, durability, as well as service life and maximize equipment uptime in harsh industrial environments.
These equipment upgrades become especially important across factory automation, building transportation, off-highway vehicle, oil and gas, and amusement park industries.
“When a machine is down, checking the encoder is a standard part of many industrial troubleshooting workflows,” said Sal Deluca, Global Product Manager, Dynapar. “However, without an oscilloscope, they can be black boxes that take time to diagnose, leading to wasted effort, needless replacement, and unnecessary downtime. Our HS35iQ encoder with PulseIQ technology transforms this workflow by providing specific fault indication that allows you to rule out the encoder or correct the root cause immediately and avoid repeat issues. They’re especially well-suited for use in automated conveyor and material handling and packaging applications.”
Talk about these encoders on a slightly deeper level, we begin from their phased array, wide-gap encoder engines that are equipped with unbreakable plastic code discs, capable of delivering up to 20,000 pulses per revolution (PPR), IP67 junction boxes for field wiring, rated operating temperatures extending from -40°C to +100°C. Alongside that, we have an independently validated ability to withstand up to 400g shock and 20g vibration.
Another detail worth a mention is rooted in HS35R encoders’ compact, modular design that simplifies maintenance and replacement. They feature aluminum housings with IEC flanges starting at 2.5″, 5/8″ shafts, and two large-gauge, oversized bearings that can handle excessive shaft loading up to 100lbs axial and 50lbs radial.
They also feature standard mounting dimensions and customizable mounting options, including direct motor and driveshaft mounting with three different tethers and a torque arm with an optional grounding strap. Markedly enough, these options don’t require any couplings, flowerpots, or matching flanges, thus eliminating components and points of failure and facilitating quick and easy installation and replacement
Apart from that, we have IP64 or IP67 sealing and six interfaces: open collector, open collector with pull-up, push-pull, DLD7272, DLD 4469, and high-power MOSFET line driver options.
Turning our attention towards Dynapar’s HS35iQ programmable hollow-shaft encoders with PulseIQ technology, it is essentially a future-ready self-diagnosing feedback device geared towards supporting predictive maintenance strategies, minimizing downtime through rapid diagnostics, and meeting Industry 4.0 requirements.
Complementing this would be an assortment of advanced onboard PulseIQ diagnostics, color-coded LEDs, and digital outputs that provide real-time status updates and specific visual fault indications for issues like coupling and shaft slips, cable faults, shaft and bore mismatch, overspeed, temperature drift, and insufficient voltage.
From a practical standpoint, these features prevent unsafe operating conditions and confirm when faults have been resolved, while simultaneously recommending corrective action to help users confidently address the root cause in as few steps and little time as possible.
HS35iQ encoders are also capable of storing recent lifecycle and fault status data in the onboard memory, which is accessible via PulseIQ Encoder Software. This software further helps users configure fault conditions for overspeed, temperature, and output voltage warnings and errors, and operating conditions, including resolution, phase direction, and Z-index pulse polarity,
In case that wasn’t enough, the stated assortment of intelligent optical incremental encoders boast compact aluminum housings with IEC flanges starting at 2.5″, hollow bores ranging from 6mm to 1.25″, standard mounting dimensions, and a direct-shaft mount configuration with three different tether options.
“And for use cases that don’t require smart solutions — like some cranes and hoists — our modular, heavy-duty HS35R encoders provide rugged reliability, durability, long-lifetime performance, and broad application suitability in a variety of harsh environments,” said Deluca
