Product Positioning

The 3SE5000-0AA21 is a torsion arm drive head with a Form A configuration. The arm length of 21mm is the shorter version in the series, making it suitable for installation environments with limited space. It is used with the SIRIUS 3SE52 position switch body.

Core Product Advantages and Features
Form A short arm design
With an arm length of 21mm, it is a more streamlined size in the series and is suitable for installation locations with limited space.
19mm plastic rollers
The rollers are lightweight and move smoothly, reducing wear on the surface of the object being tested.
Compliant with EN 50047 standard
The dimensions conform to European standards, making it easy to assemble with the 3SE52 series switch body.
Lightweight
It weighs approximately 0.014 kg, making it easy to install on-site and manage spare parts.

Product Positioning

The 3SE5000-0AA03 is a torsion arm type drive head with an arm length of 27mm and a ball bearing roller design, which has lower frictional resistance than ordinary plastic rollers. It is suitable for use with the SIRIUS 3SE51 position switch body for high-frequency operation applications.

Core Product Advantages and Features
Ball bearing roller
The 19mm rollers have built-in ball bearings, resulting in low rotational resistance, extended service life, and reduced wear.
27mm arm length design
The arm has a 9mm step difference to balance the trigger stroke and installation space requirements.
Metal arm structure
Made entirely of metal, it possesses excellent mechanical strength and stability.
Suitable for high-frequency movements
The low-friction roller design is particularly suitable for detection applications involving frequent movements.
