Compatible with SCHUNK J02 and MMS magnetic proximity switches to detect fully open / fully closed jaw positions.

4. Scenari applicativi tipici

Robot loading/unloading, 3C component handling, small metal part assembly

Machine tool automatic feeding, packaging sorting, clamping of small die-cast & stamping parts

General production lines with moderate dust; dust-resistant upgraded model PGN-plus 64-1-IS available for harsh dusty environments.

5. Optional Matching Accessories
6. Proximity Switches: MMS22-SPM8 / JGZ magnetic switches (jaw position feedback)
7. Extended Custom Fingers: Standard steel or polyurethane anti-slip gripper fingers
8. Adapter Flanges: ISO9409 standard robot mounting flanges
9. Dust-proof Kits: For upgrading protection in heavy dust environments
10. Model Distinction Tips

Two base variants available for PGN-plus 64, do not confuse:

0371090 PGN-plus 64-1: 6 mm single-side stroke (standard short-stroke version, your target model)

0371091 PGN-plus 64-2: 10 mm single-side stroke (long-stroke version)

7. Model Selection Pitfall Avoidance
8. Upgrade to PGN-plus 80 if workpiece weight exceeds 1.25 kg
9. Gripping load capacity drops drastically when finger length exceeds 90 mm; derating is mandatory
10. Corrosion-resistant dust-proof variant required for operating temperatures over 90 ℃ or continuous cutting fluid immersion
11. Standard IP40 unit cannot be directly used in vacuum or explosion-proof hazardous areas

Parametri di base

Key Differences in Overall Mounting Dimensions

1. PGN-plus 50

50 mm body width, compact design for miniature 3C component handling; preferred for small robot end effectors. Low load capacity; severe load derating required for extended fingers.

2. PGN-plus 64-1 (371090)

Balanced general-purpose model with compromise stroke, gripping force and footprint. Widely adopted for machine tool loading/unloading and standard automation stations with excellent versatility.

3. PGN-plus 80

High-load variant compatible with long gripper fingers, designed for metal stamping parts, heavy plastic workpieces and machined blanks; larger overall size requires more installation space.

Linee guida per la selezione

1. Workpiece weight ＜0.7 kg, limited installation space → PGN-plus 50
2. Workpiece weight 0.7～1.25 kg, general automation, moderate mounting space → PGN-plus 64-1 (371090)
3. Workpiece weight 1.25～2.0 kg, long finger application, heavy-duty materials → PGN-plus 80

Supplementary Stroke Differentiation for Size 64 Serie

0371090 PGN-plus64-1: 6 mm single-side stroke (versione standard, your target model)

0371091 PGN-plus64-2: 10 mm single-side stroke, larger stroke with slightly reduced gripping force under identical air pressure

Repetitive Positioning Accuracy of SCHUNK PGN-plus 50

Specificazione standard: ±0.01 mm

Supplementary Explanations

1. Unified Accuracy Across the Series

All standard PGN-plus 50 / 64-1 (371090) / 80 models share identical ±0.01 mm repetitive positioning accuracy, achieved via multi-tooth guide rails and wedge cam drive structure for high-precision repetitive clamping.

2. Accuracy Definition

Maximum position deviation of jaw reference surface after 100 consecutive open-close cycles.

3. Factors Degrading Accuracy Performance

Extended finger length beyond rated maximum amplifies positional deviation at finger tip

Unstable air pressure, oil/water contamination in air supply and rail dust ingress cause long-term wear and accuracy degradation

Camera bianca / dust-proof SD variants maintain precision better than standard IP40 units over service life

4. High-Precision Upgrade Option

Select PGN-plus-P precision enhanced series for tighter guide clearances and superior long-term dimensional stability. Nominal repetitive accuracy remains ±0.01 mm, with core advantage of minimal deformation under prolonged operation.

SCHUNK PGN-plus 50 Metodi di montaggio

The gripper body supports 3 standard mounting orientations (metter il fondo a, superiore, side) with locating pin holes for centering; installation can be upright, inverted or side-mounted with no angular restriction.

1. Detailed Introduction to Three Body Mounting Configurations

(1) Bottom Mount (Più comune, Upright Robot End Effector Setup)

Hole layout: 4×M3 internal threaded mounting holes + 2×Φ5 locating pin holes on bottom face

Applicazione: Gripper faces downward to pick workpieces, directly fastened to robot flanges, mounting plates or fixture base plates

Tightening torque for M3 screws: 0.8~1.0 N·m; matching locating sleeves are required to guarantee repetitive positioning precision

(2) Top Mount (Inverted / Overhead Installation)

Hole layout: 4×M3 threaded holes + locating pin holes on top face (full access after removing top cover plate)

Applicazione: Top-side bin feeding, upward workpiece pickup under equipment, inverted manipulator layouts

(3) Lateral Side Mount (Horizontal Side Fixing)

Hole layout: 2 sets of M3 threads + locating pin holes on each left/right side face

Applicazione: Horizontal gripping in confined spaces, side-mounted fixture fixing, multi-station parallel arrangement

2. Gripper Finger Mounting (4th Category of Assembly)

Two M3 threaded holes machined on each jaw base to secure custom or standard gripper fingers for workpiece clamping:

Fastener: M3 socket head cap screws

Coppia di serraggio: 0.1 N·m

Limiti operativi: Maximum finger extension length 70 mm, maximum single jaw self-weight ≤0.22 kg; exceeding limits drastically reduces load capacity and positioning precision

3. Two Air Supply Installation Forms
4. Conventional External Tubing Connection: Front M5 threaded A/B ports (G1/8 for 64/80 modelli) fitted with push-in quick connectors
5. Hose-less Integrated Air Supply (Direct Valve Plate Connection): Air routed internally through mounting plate bores without exposed tubing, ideal for compact cabinet layouts
6. Montaggio & Punti chiave della selezione
7. Uniform M3 thread size and interchangeable locating pins across all three mounting orientations; shared adapter plates compatible
8. Lateral mounting generates higher bending moment; bottom/top mounting is preferred for extended finger applications
9. Locating sleeves must be fitted for high-precision processes to avoid assembly offset compromising ±0.01 mm repetitive accuracy
