Global safety light curtain with muting, Type 4
|
|
Just as with the SF4-A series, the SF4B series remains impervious to interference from extraneous light. However, the SF4B series is more compact, includes muting control circuits in the light curtian and an override function that allows a manufacturing line to restart operation after the line has been stopped, even while muting control was active. These functions all contribute to a light curtain that provides greatly improved safety with no loss in productivity. Now also available with new corner mirrors for less work and less wiring. A large reduction in cost!
Characteristics:
- More than 40 models for finger, arm or body protection

- OSSD1 and OSSD2 NPN/PNP switchable
- Muting integrated
- Fixed and floating blanking
- Display with error code
- Series connection
- Mutual interference prevention (ELCA)
- Override
Accessories:
- Extension cables
- External relay unit
- Cables for series connection
