AX73 Stainless Steel ATEX Absolute Rotary Encoder with Profibus

The ATEX-approved Hengstler AX73 absolute rotary encoder with Profibus technology (Process Field Bus), made of high-grade stainless steel, is used in atmospheres where mists, gasses, vapours, or clouds of dust are present, where atmospheres are dangerous or have the potential to combust.

Profibus is one of the most well-known fieldbus communication protocols used in many areas of industrial automation, developed by its members to share a common technical platform for seamless communication and integration of components to offer flexibility and reduce cost.

The Hengstler EX-certified AX73 absolute rotary encoder complies with the ATEX directive for use within Group II Category 2, zones 1 and 21 (gas and dust).

The AX73 encoder is constructed using high-grade stainless steel housing (1.4404/316L) for the most volatile conditions, particularly suited where high corrosion resistance is an absolute necessity.

Mounting options are clamping flange with resolutions up to 14-bit single-turn and 12-bit multi-turn. The shaft size is 10mm, with a protection class rating of IP67.

The supply voltage is 10 to 30V DC. A user-friendly terminal box with M20 threaded connections offers a free choice of cable connection, and the removable casing provides fast and easy field installation.

Encoders are RoHS-compliant and CE-marked.
