Marsh Bellofram Automatic Timing & Controls 7706 Series Convergent Beam Laser Sensor

Product catalog summary

Overview: The 7706 Series Convergent Beam Sensor is designed for small object detection with a sensing capability of less than 2mm. It operates on a supply voltage of 10-30 VDC and features dual output configurations (PNP & NPN). The sensor is equipped with background suppression beyond 4-1/2 inches and offers selectable light-on and dark-on operation modes.

Specifications:

Supply Voltage: 10 to 30 VDC
Supply Current: 30 mA maximum
Output Configuration: One current sourcing (PNP) and one current sinking (NPN) open collector transistor
Output Rating: 200 mA maximum each output with specific voltage saturation levels
Output Protection: Protected against current overload and inductive transients
Response Time: Less than 2 ms, >500 Hz
Indicators: Power (Red), Output On (Green)
Adjustments: Single turn intensity control, two position light/dark operate switch
Sensing Beam: 670 nm visible red
Average Output Power: Less than 150 nW
Sensing Ranges: Available in 4", 6", and 8" versions with specific ranges for different reflectivity levels
Housing: NEMA 6
Connector: 4 pin, M8x1, pico style
Operating Temperature: 32° to 104°F (0 to 40°C)
Weight: Less than 1 oz.

Model Number: The model number includes type, operation, power requirements, beam type, and output features. For example, 770 04 N 3 B indicates a 4" sensing distance with switch selectable operation.

Accessories: Various connectors, cables, reflective tapes, and retro-reflectors are available to complement the sensor's functionality.

Wiring: The sensor includes a detailed wiring guide with color-coded connections for power, NPN, common, and PNP outputs.
