Basic Red R LED Blue GND Green +VS RP Output Note: Customer has to select suitable resistors for chosen supply voltage. Pull-up resistor RP could be e.g. 10 k depending on desired output. Forward voltage of LED is 1.3 V and LED current should be 10 mA (depending on application liquid). RLED can be calculated as follows (e.g. for VS=12 V): RLED = ( VS - 1.3) V 12 - 1.3 = = 1070 1.1 k 10 mA 0.01 TTL compatible (high in air) TTL compatible (low in air) Red +VS 4.7 Red +VS Green Output GND Green Output GND Blue Blue Push-Pull (current sinking and sourcing) Red +VS RL RL Green Output GND Blue September 2008 / 635 3/4 www.sensortechnics.com OLP Series Polysulphone optical liquid level switches ORDERING INFORMATION Basic and TTL compatible output types Output Series Current Options OLP 01B : 01T: Type Function 0: Low i n ai r F: M10 thread K: M12 thread short 3: 3 wire 4: 4 wire* * on request, MOQ may apply Housing type 10 mA basic* Termination 10 mA TTL compatible 1: High in air * Low in air only Example: OLP 01T 0 F 3 Transistor output types Output Series Current Options OLP 25X : 25U : 50U : Type (VS= 5...16 V) Housing type Function 0: Low i n ai r 1: High in air L: M12 thread long 250 mA Push-Pull 250 mA Push-Pull (VS= 10...28 V) Termination 3: 3 wire 4: 4 wire* 500 mA Push-Pull * on request, MOQ may apply Example: OLP 50U 0 L 3 Accessories (please order separately): * Nuts, available in Plastic, Nickel Plated Brass or Stainless Steel * Washers, available in VAMAC (for high temperature) and Nitrile (for standard temperature) Note: Custom specific options are widely available!
