SICK WT24-2X260 Overview
Photoelectric Proximity Switch WT24-2X260 Version: Ex II 2G EEx ia IIC T4
SICK WT24-2X260 Description
- Classification: EX II 2G Ex ia op is IIC T4 according to Directive 94/9/EC (ATEX)
- Corresponds to Category 2G
- Output type: EN 60947-5-6 (NAMUR)
- Long sensing range with very precise background suppression
- M12 or terminal chamber connection: 90 rotatable
- Durable metal housing
- Allows longer sensing range despite the limited factors of the norms for Category 2G (ATEX, explosive environments)
- Metal housing that has been IP 69K tested provides reliability and a long service life
- Flexible installation due to 90 rotatable connector
