Practical notes on electric gripper basics — stroke, gripping force, jaw count, finger design, control interfaces and servo vs stepper drives — to help you write a clear specification before asking for a quote.
Start with the job, then the row of numbers A datasheet is only useful if you read electric gripper specifications in the same order you commission a tool: how far the jaws must move, how hard they must hold, how repeatable the place position must be, how fast one open or close may take, then … Read more
How an integrated gripper controller changes flange weight, cabinet space, cable routing, heat and repair time, and when a separate unit still wins.
How many jaws gripper contact points a part needs: two for flats, three for round parts, four for thin panels, plus the checks that confirm the final choice.
Servo vs stepper gripper compared: how open-loop stepping and closed-loop servo control differ on force consistency, feedback and installed cost in a real cell.
Electric gripper communication interfaces compared: discrete I/O, RS485, Modbus and fieldbus, plus the data each carries and the checks to make before wiring.
Electric gripper stroke is a range, not a single number. Learn how finger thickness, part variation and approach clearance set the opening your cell needs.
Gripping force is the force a gripper applies to a part. Learn why static force is not enough, how friction and contact area change the result, and how to state a force requirement.
Parallel gripper vs 3-jaw gripper: how each one holds a part, which shapes suit each design, and why finger design decides the result more often than the mechanism.
Electric gripper vs pneumatic gripper: compare force control, stroke, position feedback, and total system cost to see which technology fits your handling task.
A robot gripper is the end-of-arm tool that holds a workpiece. Learn the main gripper types, what a gripper actually does, and what to prepare before asking for a quote.
