Product Overview

The EUCHNER HBA-079827 is a comprehensive hand-held pendant station from the HBA series, designed to provide safe and intuitive operator control for machine setup, troubleshooting, and maintenance applications. This rugged pendant integrates multiple control elements into a single ergonomic enclosure, allowing machine operators to perform axis positioning, program verification, and emergency stops while positioned at the point of operation, eliminating the need to return to a fixed control panel.

The pendant features a 100-pulse handwheel with a wear-free magnetic detent mechanism, delivering precise positional feedback for manual axis jogging and incremental positioning. The device includes a dual-channel tamper-proof emergency stop device conforming to EN ISO 13850, two 2-stage enabling pushbuttons (each with one normally open contact), two 5-position selector switches (offering selection options X, Y, Z, 4, 5 and 0, 1, 10, 100, 1000), and three membrane pushbuttons each with normally open contacts. All controls are housed in an IP65-rated polycarbonate enclosure, suitable for use in industrial environments with exposure to dust, oil mist, and coolants.

Technical Specifications

Key Features

• 100-pulse handwheel with wear-free magnetic detent mechanism provides precise, tactile incremental positioning feedback for manual axis control.

• RS422 differential output ensures reliable pulse signal transmission even over extended cable lengths in electrically noisy environments.

• Dual-channel tamper-proof emergency stop (EN ISO 13850) with two positively driven contacts delivers failsafe emergency stopping compliant with international safety standards.

• Two 2-stage enabling pushbuttons allow safe machine operation by requiring deliberate two-stage actuation before enabling motion commands.

• Two 5-position selector switches (Gray coded) provide efficient axis selection and step size adjustment for multi-axis machine setups.

• Three membrane pushbuttons offer additional control functions for program execution, data entry, or auxiliary machine functions.

• IP65 protection rating permits operation in dusty industrial environments and resists splashing water, coolants, and oil.

• Robust polycarbonate enclosure withstands industrial impacts and provides chemical resistance to lubricants and cleaning agents.

• 23-pin metal circular connector provides secure, reliable electrical connection with shielding for EMC protection.

• Coiled cable (3.775 m extended length) allows operator mobility while managing cable routing to prevent tangling or snagging.

Applications

The EUCHNER HBA-079827 hand-held pendant station is deployed across a wide range of industrial machinery requiring manual operator control at the point of work. In CNC machine tools, the pendant provides manual axis jogging (handwheel) for setup, tool alignment, and workpiece inspection, with enabling pushbuttons ensuring safe machine motion control. For robotics and automation cells, the pendant enables safe manual positioning of robot axes during program teaching, fault recovery, and maintenance operations, with the dual-channel emergency stop providing immediate safety shutdown capability.

Additional applications include injection molding machines (manual mold setup and nozzle alignment), stamping presses (die change and setup operations), packaging machinery (film threading and changeover), and printing presses (web threading and registration setup). For system integrators and machine builders, the HBA-079827 simplifies compliance with EN ISO 13849 safety requirements by providing integrated safety-rated components (emergency stop and enabling switches) in a single, certified pendant assembly. The selector switches permit rapid toggling between axes, speed ranges, or operational modes, making the pendant particularly suitable for machines with complex manual setup procedures requiring frequent selection changes.
