Tri-Tronics Company, Inc. General Purpose Photoelectric Sensor EZPRF4S

For documentation and other EZ-PRO™ models, please see our EZ-PRO™ Marketing Page. Technical Features Model Specific Adjustment Type: Push Button Connection Type: Cabled, 6ft. Housing Type: DIN Rail Optical Block: Type F4S, Glass Fiberoptics Adapter for use with a wide variety of glass fiberoptic light guides for both the proximity and opposed sensing modes. LED Light Source Red = 660nm Best choice for use with plastic fiberoptic light guides. Useful when sensing translucent objects in proximity (Beam Make) mode. Useful when sensing transparent objects in fiberoptic retroreflective (Beam Break) mode. Can be polarized for retroreflective (Beam Break) sensing to reduce proxing on shiny objects. Opposed fiberoptic light guides can be polarized for sensing some translucent plastic containers; consult factory for details. Used as red filter for color perception advantages. Sensing Range: Opposed Mode with F4S: 1ft. Opposed Mode with F4S and lens: 20+ft. Proximity Mode with F4S: 5in. using a .125in diameter fiber bundle Proximity Mode with F4S and lens: 1ft. using a .125in diameter fiber bundle 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 Sensor outputs can sink or source up to 150mA (current limited) All outputs are continuously short circuit protected Response Time Light/Dark state response = 300 microseconds Hysteresis: "Factory-set" for high resolution - less than one bar on the Contrast Indicator Pushbutton Control: Yellow/Blue - AUTOSET Manual Adjustments Set status of three options: 5) Lock, 4) Auto-Trac, 3) Timers: 10ms, 25ms, 50ms Diagnostic Indicators: 5-LED bar graph 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 5 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 action alert is activated. Also indicates when ACT adjusts sensor Light Immunity: Responds to sensor’s pulse modulated light source, resulting in high immunity to most ambient light, including indirect sunlight or strobes Ambient Temperature: -40°C to 70°C (-40°F to158°F) Rugged Construction: Chemical resistant, high-impact polycarbonate housing Waterproof ratings: NEMA 6 and IP67 Conforms to heavy industry grade CE requirements
