OMRON Robotics
i4-750
High-speed 4-axis SCARA robot with 750 mm reach and 15 kg payload, the mid-reach member of the i4H family between the 650 mm and 850 mm variants, for precision assembly, dispensing, and pick-and-place.
Full specifications
Performance
How much it lifts, how far it reaches, how precisely it repeats.
- Payload
Maximum mass the robot can carry at the wrist flange, including the gripper/tool. Higher means it can handle heavier parts.
- 15 kg 74th pct in class
- Reach
Maximum horizontal distance from the base axis to the wrist — defines the size of the work area. Higher means a larger envelope.
- 750 mm 67th pct in class
- Repeatability
How close the robot returns to the same taught point on repeated tries (ISO 9283, ±). Lower is better — tighter precision.
- 0.015 mm 43th pct in class
- Axes (DOF)
Number of independently driven joints / degrees of freedom. 6 is standard for articulated arms; 4 for SCARA/palletizers; 7 adds elbow redundancy.
- 4
- Std cycle time
Time for a standard 25/305/25 mm pick-place move where published. Lower is faster.
- 0.39 s 13th pct in class
- Wrist torque
Allowable torque at the wrist axis — how much twisting force a tool can apply. Higher handles bigger/offset tools.
- 8 N·m 75th pct in class
- Wrist inertia
Allowable moment of inertia at the wrist — how much rotating mass it can swing without overload. Higher is more capable.
- 0.5 kg·m² 78th pct in class
Motion range & speed
Per-axis travel limits and rotational speeds.
- Max axis speed
Highest rotational speed of the fastest joint. Higher helps short, fast moves.
- 2,400 °/s 61th pct in class
Motion range and maximum speed per joint.
| Axis | Range | Max speed |
|---|---|---|
| J1 | -152° to 152° | 450 °/s |
| J2 | -140° to 140° | 720 °/s |
| J4 | -360° to 360° | 2400 °/s |
Physical
Size, mass and how it mounts.
- Robot weight
Mass of the manipulator (arm) without controller. Lighter eases mounting and mobile use; heavier often means stiffer/higher payload.
- 51 kg
- Mounting
Orientations the robot can be installed in (floor, ceiling/inverted, wall, tilted, mobile base).
- floor
Power & controller
Electrical supply and the control cabinet that drives it.
- Power supply
Required input voltage / phase for the controller.
- 200-240V AC single-phase
- Controller
The control cabinet / unit that runs the robot.
- Sysmac NJ/NX
Environment
Conditions it can operate in — dust, water, temperature, cleanliness.
- IP rating (arm)
Ingress protection of the body against dust/water (IEC 60529). First digit = dust, second = water. Higher resists harsher environments.
- IP20 0th pct in class
Safety
Standards met and collaborative-operation capability.
- Collaborative
Whether the robot is designed to work safely next to people without fencing (power-and-force-limited).
- No
- Safety standards
Certified safety standards (ISO 10218-1, ISO/TS 15066) and functional-safety level (PLd/PLe, SIL2/3).
- ISO 10218-1
Control & software
Programming, languages and ecosystem.
- Programming
How the robot is taught: pendant, hand-guiding (lead-through), block/flow-chart, scripting, offline simulation.
- offline-programming, teach-pendant
- Languages
Native robot programming language(s) — e.g. KRL (KUKA), RAPID (ABB), URScript (UR), INFORM (Yaskawa).
- IEC 61131-3
Connectivity & I/O
Signals, fieldbuses and tooling interfaces.
- Fieldbus
Industrial networks supported for PLC/cell integration (PROFINET, EtherNet/IP, EtherCAT, Modbus TCP, CC-Link, etc.).
- EtherCAT, EtherNet/IP, PROFINET
Safety certifications
- ISO 10218-1 — the primary industrial-robot safety standard covering design and construction requirements
