Technical Features
Model Specific
Adjustment Type:
Push Button
Connection Type:
Cabled, 6ft
Housing Type:
DIN Rail
Optical Block:
Type F5, Plastic Fiberoptics Adapter for use with a wide variety of plastic fiberoptic light guides for both the proximity and opposed sensing modes.
LED Light Source
White = Broadband Color Spectrum) Best choice for detecting all printed registration marks on packaging material. Recommended for detecting dark colored objects in the proximity (Beam Make) mode. Best choice for sorting colored objects.
Sensing Range:
0.25in range
Family Specific
Supply Voltage:
10 to 30 VDC
Polarity Protected
Current Requirements:
45mA (exclusive of load)
Output Transistors:
(1) NPN and (1) PNP sensor output transistor
Outputs sink or source up to 150 milliamps (current limit)
All outputs are continuously short circuit protected.
Remote AUTOSET Input:
Opto-isolated momentary sinking input (10 milliamps)
Response Time
MEP45WL – Light/Dark = 45μs Repeatability = 13μs
MEP – Light/Dark = 175μs
Push Button Control:
AUTOSET
Manual Adjustments
Set status of 5 options: 5) Lock, 4) Output Invert, and Pulse Stretchers 3) 10ms, 2) 25ms, and 1) 50ms
Hysteresis:
Set for high resolution … less than one bar on the contrast indicator
Light Immunity:
Responds to sensor’s pulsed modulated light source … immune to most ambient light and strobes, including indirect sunlight
Diagnostic Indicators:
5-LED Bargraph functions in one of two modes: 1. Contrast Indicator… Displays scaled reading of sensor’s response to contrasting light levels (light to dark) 2. Status Indicator…Displays status of five selectable options
Red LED output indicator … Illuminates when the sensor’s output transistors are “ON” NOTE: If Output LED flashes, a short circuit condition exists
Amber LED…Illuminates when in the options select mode
Yellow LED…Illuminates when Lock feature is activated
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
Ambient Temperature:
-40°C to 70°C (-40°F to158°F)
Rugged Construction:
Chemical resistant, high-impact polycarbonate housing
Waterproof, NEMA 4X, 6P and IP67 enclosure ratings
Epoxy encapsulated for mechanical strength
