AAC Single Beam
|
Description
The Area Access Control (AAC) safety single-beam is a 24V DC through-beam opto-electronic safety switch offered with two operating ranges (a short range (0.5…20 m (1.64…65.5 ft) or a long range (15…70 m (49.2…300 ft)) system. The AAC system uses the same transmitter for both ranges and one of two receivers for a short-range or long-range system. This unique system configuration minimizes the number of cat. nos. necessary for specifying the AAC single-beam system.
The AAC safety single-beam is used as a whole-body detection device. The light beam produced between the AAC transmitter and receiver provides whole-body access detection for hazardous areas such as:
- Robotic work cells
- Processing machines
- Machining centers
- Palletizers
- Transfer lines
- High bay warehouses
Features
- Long scan range (up to 70 m (300 ft))
- Easy installation
- Die cast aluminium housing
- Heated front lens, allowing use even in outdoor applications
- Relay outputs
