XY25XS

Product catalog summary

Overview

This document provides the standard properties, test procedures, and optional configurations for the XY25XS actuator developed by CEDRAT TECHNOLOGIES. It details the technical conditions under which the actuator's performance is measured and guaranteed.

Technical Conditions of Use and Measurement

Mounting Conditions: Free-free (actuator not fixed) and Blocked-free (actuator fixed to an infinitely stiff mechanical support).
Excitation Types: Quasistatic excitation with AC voltage between -20 V and 150 V at 1 Hz; Harmonic excitation with 0.5 Vrms sinusoidal voltage from 0 to 100 kHz; Maximum harmonic excitation defined by max displacement at resonance frequency.
Measurement Methods: Displacement measured via laser interferometer or capacitive displacement sensor; Admittance measured using HP 4194 A or Cypher C60 impedance analyzers.
Environmental Conditions: Ambient temperature between 15-25°C and dry air with humidity below 50% relative humidity.
Note: Deviations from these conditions may cause temporary or permanent changes in actuator properties; users are advised to consult CEDRAT TECHNOLOGIES before non-standard use.

Factory Tests Conducted

Electrical admittance versus frequency (free-free condition)
Displacement versus input voltage
Sensor gain and linearity
Step response in closed loop
Stability in closed loop

Available Options

Strain Gauges (SG)
Eddy Current Displacement Sensor (ECS)
Specific Interface (SI)
Non-magnetic version (NM) - optional
Vacuum compatibility (VAC)
Specific version or customization (SV)
