Optical and magnetic angular position sensing principles in Hengstler devices

Hengstler rotary position encoders utilize two complementary physical sensing technologies: high-resolution optical scanning and interference-resistant magnetic tracking.

Optical encoders across ICURO and ACURO product lines incorporate differential receiver arrays based on proprietary Opto-ASIC microcircuits paired with precision etched glass or break-resistant mylar codewheels.

This optical architecture provides steep pulse edges, minimal phase jitter, and angular positioning accuracy down to arcseconds.

Magnetic encoder models such as the AR62 utilize Hall-effect and magnetoresistive elements, ensuring reliable operation despite lubrication fluids, airborne particulates, or intense mechanical vibration.

ACURO absolute rotary encoders: multiturn gear trains and digital buses

Hengstler ACURO AC58 absolute rotary encoders preserve true mechanical angular orientation even during total electrical power disruptions.

To track full shaft rotations, units feature a mechanical gear train without batteries or energy storage capacitors, eliminating maintenance requirements and counter failure hazards.

Devices integrate into modern industrial communication networks including Profinet, EtherCAT, CANopen, and high-speed synchronous BiSS-C or SSI channels.

Continuous transmission of operational temperature and optical signal quality diagnostics enables predictive maintenance before unexpected machinery downtime occurs.

ICURO incremental encoders: line driver configurations and shaft load ratings

The ICURO RI58 incremental rotary encoder series represents an established benchmark for automated drives and industrial motion axes.

When configuring sensors, selecting the appropriate electrical output driver is critical: differential RS422 line drivers (TTL) generate complementary signal pairs that reject electrical noise along cable runs exceeding one hundred meters, while Push-Pull stages (HTL) operating from 10 to 30 V connect directly to standard programmable controller inputs.

Dual preloaded bearing assemblies tolerate shaft loads reaching 100 N, while labyrinth shaft seals maintain environmental protection up to IP67.

Multifunctional digital counters: production monitoring and process trips

Digital multifunction instruments across Hengstler tico 731, tico 732, and tico 772 series unite discrete pulse counting, tachometry, flow measurement, and elapsed runtime logging within a compact front-panel profile.

Instruments receive pulse signals from proximity sensors, encoders, or contact closures at counting frequencies reaching tens of kilohertz.

Built-in solid-state or electromechanical relays with programmable thresholds automatically halt drive motors upon batch completion or trigger timed process intervals. Non-volatile EEPROM storage retains accumulated production totals during external electrical outages.

Forcibly guided safety relays: mechanical contact interlock mechanics

Specialized electromechanical safety relays across Hengstler H-464, H-462, and H-468 series conform strictly to the international harmonized EN 50205 standard (Type A).

The defining structural element of these switching components is a rigid mechanical link binding all internal contact sets: if a normally open contact welds shut, the opposing normally closed contact remains separated by a gap of at least 0.5 mm.

External safety monitoring circuits detect this single fault before enabling subsequent machine startup cycles, fulfilling mandatory safety loop requirements up to SIL3 and PLe.

Embedded thermal ticket printers: automated cutting in kiosk terminals

Enclosed printing modules and sub-assemblies across Hengstler C-56, e-58, and X-56 series are engineered for continuous deployment inside automated teller machines, ticketing dispensers, parking kiosks, and analytical instrumentation.

Units combine direct thermal print heads with heavy-duty guillotine paper cutters rated for over one million cut cycles. Optical media sensors detecting paper presence, low roll levels, and jam conditions enable remote monitoring of operational status.

The rigid metal chassis efficiently dissipates thermal energy during peak ticket printing throughput.
