INSTROTECH has announced Scancon’s Model: SCH88BEX, a new Atex absolute encoder with Profibus Interface.

“It’s a strong, compact (89mm footprint), cost-effective, through hollow bore encoder. Engineered for rugged conditions, it’s reliable for extra harsh environments, and is the encoder of choice for Zone 1 & 2 applications,” the company said in a statement.

The encoder has hybrid sensing technology and features optical technology for the single turn encoder, and magnetic for the multi-turn encoder.

There are no gear wheels that can wear out. The unit can be mounted directly onto the shaft and the innovative, removable end-cap allows for ease of mounting cables. It can also be mounted directly into the application without the need for any barrier, isolator or special cable.

The SCH88BEX is certified for world wide application Atex, IECEx and North American Class I Div. 1 certifications, and has the following features and advantages:

  • Hollow Shaft Encoder – ø 89 mm (ø 3.46 in.)
  • Through Hollow Bore: ø 25 mm to ø 30 mm (1.18 in.)
  • IP 66/67/68 (~ Nema 6) Environmental Protection
  • Aluminium (Chromital TCP surface treatment)
  • Material option Stainless Steel (AISI 316)

According to the company, applications for the device are found primarily in the industrial oil and gas fields, heavy industry, agriculture, marine and shipping, as well as for cranes.

A Fibre Optic Ex-Proof version is available for Atex Zone 1 applications, that eliminates signal degradation due to electrical noise issues.
