Overall Dimensions and Specifications
The document provides detailed specifications for the ATL 12 linear actuator, including dimensions for front and rear attachments, stroke lengths, and various components such as the pin, capacitor, and rear bracket. The actuator features a standard head with a threaded hollow bore and options for different end attachments like ball joint, clevis end, rod end, and flange end.

Performance and Features
The actuator can handle push loads up to 11,000 N and pull loads up to 8,000 N, with linear speeds reaching up to 93 mm/s. Standard stroke lengths range from 100 mm to 800 mm, with custom lengths available upon request. The housing is made of aluminum alloy with a bronze bush, and the push rod is chrome-plated steel. The actuator is equipped with an AC 3-phase or 1-phase motor and has a standard protection rating of IP55 (IP54 with brake). It operates with a duty cycle of 30% over 10 minutes at temperatures between -10°C and +40°C.

Accessories and Options
Available accessories include different front attachments, stainless steel push rods, rear brackets, mechanical overload protection, brake motors, and adjustable stroke end reed switches. Options for motor mounting positions and fixing attachments are also provided.

Stroke End Switches and Positioning Control
The document details the use of magnetic and electric stroke end switches for positioning control. Magnetic reed switches are activated by a magnetic field and require a wiring control circuit. Electric stroke end switches are installed in a sealed plastic box and can be configured for normally closed or open contacts. The switches are adjustable and equipped with signaling LEDs and protective varistors.

Ordering and Configuration
An example ordering code is provided, illustrating how to specify the actuator, selected ratio, required stroke, motor, stroke end switches, and accessories. The document emphasizes the importance of proper connection to a wiring control circuit for the switches to function correctly.
