SCH108BEX/ Absolute

Product catalog summary

Product Overview: The SCH108BEX is an Ex-proof hollow shaft encoder with a diameter of 108 mm, designed for use in hazardous environments. It supports Profibus DP-V0 interface and is available in aluminum or stainless steel housing.

Mechanical Specifications: The encoder features a through hollow shaft with diameters ranging from 25 mm to 31.75 mm. It offers IP66/67/68 environmental protection and has a bearing life exceeding 1.9 x 10¹⁰ revolutions. The maximum continuous speed is 3000 rpm, with a starting torque of less than 0.1 Nm at 25°C. It can withstand axial loads up to 250 N and radial loads up to 500 N.

Electrical Specifications: The encoder provides absolute binary coding with a resolution of up to 15 bits for revolutions and 16 bits for steps per revolution. It supports device addressing via rotary switches and Profibus interface, with an address range of 1 to 126. The supply voltage ranges from 9 V to 30 V, with typical current consumption of 150mA at 10 V and 70mA at 24 V.

Environmental Specifications: Operating temperature ranges from -40°C to +70°C, with storage temperatures up to +85°C. It can operate in 98% relative humidity without condensation.

Certifications: The encoder is certified under ATEX, IECEx, North American, and EAC Ex standards, ensuring compliance with safety requirements for explosive environments.

Terminal Blocks: The encoder includes terminal blocks for bus in and bus out connections, supporting wire sizes from 0.14 mm² to 1.5 mm².

Ordering Information: The product can be customized with different end cap types, face mounts, and anti-rotation devices. Options include various torque arm lengths and material choices between aluminum and stainless steel.
