SR-20iA
A 4-axis SCARA robot with internally routed cables, 20 kg payload and 1,100 mm reach — a clean-look, compact design for robotic assembly and packaging lines.
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.
- 20 kg 79th 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.
- 1,100 mm 91th pct in class
- Repeatability
How close the robot returns to the same taught point on repeated tries (ISO 9283, ±). Lower is better — tighter precision.
- 0.02 mm 21th 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
- Max TCP speed
Top linear speed of the tool centre point. Higher means faster cycle times.
- 2,800 mm/s 11th 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.
- 0.45 kg·m² 72th pct in class
Motion range & speed
Per-axis travel limits and rotational speeds.
Motion range and maximum speed per joint.
| Axis | Range | Max speed |
|---|---|---|
| J1 | -145° to 145° | 440 °/s |
| J2 | -145° to 145° | 500 °/s |
| J4 | -720° to 720° | 1700 °/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.
- 64 kg
- Mounting
Orientations the robot can be installed in (floor, ceiling/inverted, wall, tilted, mobile base).
- floor, wall
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
- IP rating (wrist)
Ingress protection at the wrist, often higher than the body for wet/washdown duty.
- 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
