More info

The SERF1 is a Mark II SMARTEYE with F1 optical block.

This sensor model has a Red light source.

Adjustment Type: Potentiometer adjust

The F1 Fiberoptic Adapter adapts a MARK II to any standard fiber optic light guide with .187" O.D. tips.

Mark II SMARTEYE sets the standard in photoelectric sensing. With its unique EDR circuit, it is capable of performing sensing tasks most other sensors can't accomplish. It provides extended operating ranges, enhanced background suppression, the elimination of saturation problems.

SUPPLY VOLTAGE

• 12 to 24 VDC

• Polarity Protected

LIGHT IMMUNITY

• Responds to sensor's pulsed modulated light source

• Immune to most ambient light

LED LIGHT SOURCE

• Pulse modulation rate 45 KHZ

• Choice of color:

A. Infrared = 880nm

B. Red = 660nm

C. White = Broadband Color Spectrum

D. BIue = 480nm

RUGGED CONSTRUCTION

• Chemical resistant, high impact polycarbonate housing

• Waterproof, NEMA 4X, 6P and IP67 enclosure ratings

• Epoxy encapsulated for mechanical strength

OUTPUT TRANSISTORS

• (1) NPN and (1) PNP 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 determines Output

Status:

Light = Light “ON” operate

Dark = Dark “ON” operate

INDICATORS

• OUTPUT INDICATOR - Red LED illuminates and the NPN or PNP outputs switch to the opposite state 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

• FULLY LlT: Operating near saturation

• OFF: Operating near maximum sensing range

• CONTRAST INDICATOR – Displays scaled reading of sensor's response to contrasting light levels (light vs. dark) on a ten bar LED display

RESPONSE TIME

• Minimum duration of input event

• Light state response = 50 microseconds

• Dark state response = 140 microseconds

• Leading edge Variation less than 20 microseconds

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
