Stack type actuators
Series Overview
Piezo actuators convert voltage into displacement via multilayer stacks — the most direct way to turn an electrical signal into nanometer motion. piezosystem jena actuators combine low-voltage multilayer technology with stainless-steel housings for precision, lifetime and environmental robustness.
Key Features
- Sub-nanometer resolution, microsecond-to-millisecond response
- Forces up to several kN; internal preload for push and pull loads
- Wear-free and backlash-free — billions of cycles
- Full range: standard, sealed, high-dynamics hpower and special structures
- Optional strain-gauge sensors for closed-loop operation
Typical Applications
- Precision optical adjustment and autofocus
- High-speed valve and nozzle driving
- Vibration compensation and active damping
- Micro-positioning modules in production equipment
Selection & Support
Key selection criteria: travel, force, capacitance (which determines the amplifier) and environmental conditions. As the Taiwan distributor of piezosystem jena, Nahshon provides local technical support, selection assistance and factory quotations — add your requirements to the inquiry list or contact us directly.
Product Series
Standard Series
Standard piezo actuators are the backbone of the line: travels to several hundred micrometers, forces to several kN, sub-nanometer resolution, internal preload for push-pull loads — many lengths, sensor options and full customization.Sealed Series
Sealed actuators are built for harsh environments: protective sealing keeps out moisture and contaminants while retaining standard-series precision and dynamics — piezo performance where standard parts cannot go.hpower Series
hpower high-dynamics actuators are the powerhouses: microsecond response and forces to tens of kN, sustaining large-amplitude motion at kHz frequencies with matching high-power amplifiers and cooling options.Special Structures
Special-structure actuators fill the corners standard parts cannot reach: hollow rings let light pass through, non-magnetic versions enter strong fields, ultra-compact types fit tight mechanisms — full custom capability on display.
