Details
High performance in a compact housing for AC and DC applications
The W250 family of photoelectric sensors is characterized by a special combination where both DC and AC/DC types are integrated in one highly compact housing. With a cable variant and a rotatable male connector variant, the W250 is highly flexible when it comes to system integration. Users are aided by an easy-to-read positioning indicator when adjusting sensitivity and sensing distance. Light/dark switching via a control cable cuts the number of device variants by half and reduces storage.
Benefits
- Mounting bracket is included to ease installation
- Visible red Bright Light LED for simpler alignment of the sensors
- Cable or rotatable M12 connector provide installation flexibility
- Operating mode (light/dark) is selectable via a control cable to reduce the number of device variants
- Variants with DC voltage and universal AC/DC voltage in the same housing provide increased flexibility
Features
- Easily visible red light thanks to BrightLight LED
- Potentiometer with a positioning indicator for adjusting the sensing range/sensitivity
- Light/dark switching via control cable
- Rotatable male connector or cable
- Variants for 10 … 30 V DC or 24 … 240 V DC / 24 … 240 V AC power supply in compact design
- BEF-W250 mounting bracket made of stainless steel (1.4301) included in delivery
