SCHUNK's gripper naming is systematic: the prefix defines the series, the number defines the size, and the suffix defines the function. Once you can read the name, choosing between MPG, PZN, PGN, DPZ and JGP becomes a matter of matching your part size and force requirement. This guide compares the parallel and angular gripper series Glorient most commonly supplies.
1. The SCHUNK Gripper Series at a Glance
| Series | Type | Typical grip force | Best for |
|---|---|---|---|
| MPG-plus | Miniature parallel | ~10–40 N | Small and delicate parts, confined spaces, high cycle rates |
| PZN-plus | Small parallel | ~20–100 N | Small-medium parts where MPG is too weak |
| PGN-plus | Universal parallel | ~50–2000+ N | The standard choice for most industrial handling |
| DPZ-plus | High-force parallel | High force-to-weight ratio | Demanding handling, high acceleration, heavy parts |
| JGP | Angular (pivoting) | Varies with size | Parts with bores or recesses, limited installation space |
2. MPG-plus and PZN-plus — The Compact Parallel Grippers
MPG-plus is SCHUNK's miniature parallel gripper line, sized for small parts, tight spaces and high cycle rates. With gripping forces in the tens of newtons and sizes down to MPG 10, it is the standard choice for small assembly cells and electronics handling. See the MPG-plus 16 as a representative unit.
PZN-plus steps up in force while staying compact. It suits small-medium parts where the MPG is undersized but a full-size PGN is overkill — a common gap in material handling and machine loading. See the PZN-plus 40.
3. PGN-plus — The Universal Standard
PGN-plus is the backbone of SCHUNK's range: a parallel gripper family covering from about 50 N up to several thousand newtons, with a choice of jaw guidance and accessories. If your application has no unusual constraints, the PGN-plus is usually the right answer — proven across thousands of robot cells worldwide. See the PGN-plus-P 40-AS-K.
4. DPZ-plus — High Force-to-Weight Performance
DPZ-plus delivers a higher gripping force relative to its own weight, which matters on robot arms where payload budget is tight. It is the go-to series for demanding handling tasks, high acceleration moves and heavier parts. See the DPZ-plus 40-V.
5. JGP — The Angular Gripper
JGP pivots its jaws at a joint rather than moving them in parallel. Angular grippers are ideal for parts gripped by their bore or recess, and where the gripper must reach into tight installation spaces. See the JGP-P 40-IS.
6. Reading the Suffixes
The suffix after the size tells you the function version:
- -IS — integrated inductive sensor for jaw position detection, eliminating external switches and simplifying wiring
- -V — vacuum-compatible version, sealed for vacuum handling
- -AS / -AS-K — version identifiers with specific jaw/attachment configurations
For most new machines, the -IS version is worth the small premium — position feedback makes commissioning and fault-finding significantly easier.
7. How to Choose Between the Series
- Small/delicate part, tight space → MPG-plus; slightly heavier → PZN-plus.
- Standard industrial handling → PGN-plus (the default).
- Heavy parts, high acceleration, payload-critical robot → DPZ-plus.
- Part gripped by bore, limited space → JGP.

The SCHUNK naming system exists to make repeat selection reliable: series for the family, number for the size, suffix for the function. Match all three and the right gripper is the one you already planned for.
Frequently Asked Questions
What is the difference between the SCHUNK PZN, PGN and DPZ grippers?
PZN and PGN are 2-finger parallel grippers - PGN being the larger heavy-duty range and PZN the compact universal range. DPZ is the sealed 3-finger centric gripper for round parts and dirty environments. Choose by part geometry and environment.
Which SCHUNK gripper is best for small parts?
The MPG-plus and PZN compact series are designed for small-part handling, offering high precision and short strokes. The MPG series in particular is optimised for miniature components in assembly and electronics.
What is the SCHUNK MPG series used for?
The MPG series is a small-component 2-finger parallel gripper for precision assembly, electronics and laboratory automation, featuring high repeatability and a compact profile for tight spaces.
