W 140: Miniature Photoelectric Switch Series with Large Scanning Ranges

Transcription

1 W : iniature Photoelectric Switch Series with Large Scanning Ranges Photoelectric proximity switch with adjustable scanning distance and background suppression (BGS): Scanning distance = adjustable up to mm. The integrated W electronics has parameters comparable with the big ones and convenient W details simplify handling for mounting, operation startup and maintenance, for example: Sensitivity/scanning distance D ATA S H E E T BGS Photoelectric proximity switches Photoelectric proximity switches energetic Photoelectric reflex switches Through-beam photoelectric switches TThe W is a complete photoelectric switch series in miniature housing. It especially provides extensive scanning ranges for challenging requirements. The W highlights: Through-beam photoelectric switches: Scanning range = m Accessories: Slotted masks, polarizing filter tip adapters Photoelectric reflex switch with polarizing filter: Scanning range = m (PL 8 A) Energetic photoelectric proximity switch: Scanning distance = 9 mm; for standard scanning jobs adjustment Operating reserve display Optional connection cable or 8 plug, pin or pin. The 8 plug, pin, model especially provides an extremely simple solution for the island technologies being used increasingly these days. Distributor boxes for plug modules or bus systems: plug W and play. All this and more make the W very interesting for the branches storage and conveyor technology, semi-conductor industry, electronics assembling, packaging technologies, handling and assembly systems and special mechanical engineering.
