IDEC HG1T-SA12UH-MK1363-L10 Teaching Pendant – HG1T Series

IDEC HG1T-SA12UH-MK1363-L10 — Hardwired Operator Teaching Pendant for Motion-Control and Robot Integration

The HG1T-SA12UH-MK1363-L10 is a cable-tethered operator interface device manufactured by IDEC Corporation, purpose-built for direct, deterministic interaction with industrial robots, servo-driven axes, CNC machine tools, and PLC-based motion-control architectures. Unlike panel-mounted HMIs that rely on Ethernet or fieldbus abstraction layers, this pendant establishes a hardwired, low-latency command path between the operator and the host controller — a design philosophy that remains the industry standard wherever safety-rated manual intervention is mandatory.

The MK1363 suffix designates the multi-pin locking connector assembly, while the UH housing variant provides an ergonomic, single-hand grip profile with integrated wrist strap anchor points. The L10 suffix specifies a 10-metre shielded cable, sufficient to cover the full working envelope of most 6-axis articulated robots and large-format CNC machining centres without signal attenuation or ground-loop interference.

Technical Parameters

Hardware Logical Analysis

The HG1T-SA12UH-MK1363-L10 implements a dual-channel safety architecture at the hardware level. The 3-position enable switch and the E-Stop mushroom button each occupy independent, galvanically isolated signal paths within the MK1363 connector pinout. Neither path passes through the pendant’s microcontroller or display driver — they are routed directly to the host controller’s safety relay input terminals. This means a firmware fault in the pendant’s display subsystem cannot mask or delay a safety-stop command, satisfying the diagnostic coverage requirements of ISO 13849-1 Category 3.

The 10-metre shielded cable uses a twisted-pair topology for differential signal transmission on the serial data lines, with a dedicated drain wire bonded to the MK1363 connector shell. This construction suppresses common-mode noise from variable-frequency drives (VFDs) and servo amplifiers operating in the 2–20 kHz switching frequency range — a known EMC challenge in compact machine cells where pendant cables run parallel to motor power conductors.

The keypad matrix uses a debounce algorithm with a typical scan cycle of ≤5 ms, ensuring that jog commands are registered within one PLC scan cycle on controllers running at 10 ms task intervals. Speed-override inputs are encoded as discrete multi-bit states rather than analog voltage levels, eliminating the drift and calibration requirements associated with potentiometer-based override wheels found on older pendant designs.

The LCD backlight driver operates at a fixed PWM frequency above 1 kHz, preventing visible flicker under high-speed camera inspection systems common in automotive and electronics assembly environments. The display contrast is factory-calibrated for 0 °C to +50 °C operation without manual adjustment, using a temperature-compensated voltage reference on the LCD bias circuit.

System Integration Benefits

• Deterministic Safety Response: Hardwired E-Stop and enable-switch circuits bypass all software layers, guaranteeing stop-category performance independent of controller CPU load or communication bus state.
• Single-Cable Connectivity: All power, data, E-Stop, and enable signals are consolidated into the MK1363 connector, eliminating multi-cable routing complexity and reducing connector-related failure modes at the cabinet entry point.
• Standardized Operator Interface: Consistent keypad layout across the HG1T series reduces operator retraining time when deploying multiple machine types within the same facility.
• IP65 Ingress Protection: Sealed housing withstands coolant mist, metal swarf, and cleaning agents typical of machining and food-processing environments without requiring protective covers or enclosures.
• 10 m Working Radius: Full-length cable allows the operator to maintain line-of-sight with the tool centre point (TCP) during manual jogging of large-format robots or gantry systems, a prerequisite for safe teach-in operations per ISO 10218-2.
• Drag-Chain Rated Cable: Shielded cable construction tolerates continuous flexing in cable management tracks, supporting installations where the pendant is stored on a retractable reel or routed through a festoon system.
• Real-Time Diagnostic Transparency: Host controller status, axis position, and alarm codes are displayed on the pendant LCD without additional HMI hardware, reducing the number of devices an engineer must monitor during commissioning.
• Low Integration Overhead: Direct compatibility with IDEC FC6A and SmartAXIS Pro controllers means no custom driver development; pendant I/O mapping is handled by the controller’s built-in pendant interface function block.
• Vibration Resistance: MK1363 bayonet locking mechanism maintains electrical continuity under IEC 60068-2-6 vibration profiles, preventing intermittent disconnection in press-room or stamping-line environments.

Quality Assurance & Global Logistics

Every HG1T-SA12UH-MK1363-L10 unit supplied by siemensplc.com is sourced directly from IDEC Corporation’s authorized distribution network. Each pendant carries the manufacturer’s original lot code and date code label, enabling full traceability back to the production batch. Prior to dispatch, our technical team performs a pre-shipment inspection covering keypad actuation force, display pixel integrity, E-Stop continuity (measured at <0.1 Ω contact resistance), enable-switch three-position logic verification, and cable shield continuity end-to-end.

Units are packed in original IDEC anti-static foam inserts with the factory datasheet and conformity declaration included. Export documentation — including commercial invoice, packing list, and certificate of origin — is prepared for all international shipments. Customs HS code 8537.10 is applied by default; alternative classification is available on request for specific destination markets.

Shipments originate from our warehouse in Xiamen, China. Standard export carriers include DHL Express, FedEx International Priority, and SF Express International, with typical transit times of 3–7 business days to Europe, North America, Southeast Asia, and the Middle East. Air freight consolidation is available for multi-line orders. All shipments include full tracking and are covered by cargo insurance up to declared value. For time-critical requirements, same-day dispatch is available for orders confirmed before 14:00 CST.
