SE3BC

Adjustment Type:

• Potentiometer

Connection Type:

• Connector, 4-pin M12

Housing Type:

• DIN Rail

Optical Block:

• None.

LED Light Source

• Blue = 480nm
  Useful for detecting translucent, transparent, plastic, or glass objects in the retroreflective mode when using the R4 optical block. Used as blue filter for color perception advantages, i.e. resolving yellow vs. white colored objects or printed registration marks.

Sensing Range:

• Depends on Optical Block

Supply Voltage:

• 12 to 24 VDC
• Polarity Protected

Current Requirements:

• 85mA (exclusive of load)

Output Transistors: 

• (1) NPN and (1) PNP sensor output transistor
• NPN Sink up to 150mA
• PNP Source up to 150mA
• Momentary short circuit protected
• Outputs protected from pulsing during power up
• Light/dark switch de4termines output status
  Light = Light "ON" operate
  Dark = Dark "ON" operate

Response Time

• Minimum duration of input event
• Light state response = 50 microseconds
• Dark state response = 140 microseconds
• Leading edge variation less than 20 microseconds

Hysteresis:

• Less than 400 millivolts for maximum sensitivity and resolution

Light Immunity:

• Responds to sensor’s pulse modulated light source
• Immune to most ambient light

Ambient Temperature:

• -40°C to 70°C (-40°F to158°F)

Indicators:

• OUTPUT INDICATOR – RED LED illuminates when the output transistors are in the “ON” state as determined by the position of the Light/Dark switch
• BEAM STATUS INDICATOR – RED LED illuminates when returned light level exceeds “5” on the CONTRAST INDICATOR
• EDR^® INDICATOR – Intensity of GREEN LED provides indication of where in the dynamic operating range the OFFSET/EDR^® adjustment has been set
• CONTRAST INDICATOR – Displays scaled reading of sensor’s response to contrasting light levels (light vs. dark) on a 10 bar LED display

OFFSET/EDR^® Adjustment:

• Sets initial level on CONTRAST INDICATOR in relation to mid-scale switch point of 5 – functions as sensitivity adjustment
• Controls Enhanced Dynamic Range circuit (EDR^®) which functions to avoid saturation

Rugged Construction:

• Chemical resistant, high-impact polycarbonate housing
• Waterproof, NEMA 4X, 6P and IP67 enclosure ratings
• Epoxy encapsulated for mechanical strength
