Linear actuator CAHB series

Product catalog summary

Introduction to CAHB Series
The CAHB series of linear actuators are designed for diverse applications, offering high reliability and minimal maintenance. They are suitable for various load applications and feature integrated controllers, overload protection, and high ingress protection ratings.

Performance Overview
The series includes multiple models with specific force, speed, stroke, and voltage specifications. Smart versions (CAHB-20S, -21S, -22S) offer advanced features like integrated controllers and CAN bus communication.

Specifications

CAHB-10: Compact and robust, offering push and pull forces from 120 N to 1500 N, speeds from 5 to 56 mm/s, operating on 12 or 24 VDC with integrated limit switches and thermal protection.
CAHB-20A: Designed for rigorous use with forces of 1500 N and 2500 N, thermal protection, and optional potentiometers and limit switches, operating at 12 or 24 VDC.
CAHB-20E and -20S: Focus on high productivity and reliability, featuring overload protection, corrosion-resistant materials, and enhanced ingress protection, with manual override options.

Electrical Specifications
Detailed specifications for models CAHB-20E, -21E, -22E, and their smart counterparts, covering voltage, current, and protection features.

Attachment Options
Various attachment options allow customization to specific application needs.

Environmental Tests
The CAHB series has undergone extensive testing to ensure durability and performance under demanding conditions.

Performance Data
Detailed performance data for various models, including rated push and pull forces, speed, and duty cycle percentages. Operate at nominal voltages of 12V, 24V, and 48V DC.

Mechanical Data
Stroke lengths range from 50 mm to 700 mm, with a consistent backlash of 0.6 mm. Weight for a 200 mm stroke is approximately 4.5 to 4.8 kg.

Environmental Standards
Operate in temperatures from -40°C to 85°C, with protection rated at IP69K/66M, complying with standards such as EN61000-6-2:2005 and EN61000-6-4:2007/A1:2011.

Smart Version Features
Include integrated controllers, absolute position sensors, and onboard diagnostics, supporting I/O and CAN bus SAE J1939 communication.

Diagrams and Calculations
Includes performance diagrams illustrating speed-load and current-load relationships, and dimensional drawings for different configurations.

Benefits and Features
High productivity, reliability, safety, and cost-effectiveness with features like high holding force, mechanical overload protection, and corrosion protection.

Wiring and Connection Details
Detailed wiring instructions for various configurations, including connections with position output and encoder setups.

Ordering and Configuration
Outlines ordering keys and configuration options for different models, including attachment types and CAN bus system options.

Electromagnetic Compatibility (EMC) Testing

EFT Immunity: Complies with IEC61000-4-4 standards, tested at ±2kV for power lines and ±1kV for signal lines.
Magnetic Field Immunity: Complies with IEC61000-4-8 standards, tested at 30A/m.
