| Technical Specifications |
| LER-20A |
| Supply Voltage: | 10 to 30 VDCPolarity Protected |
| Current Requirements: | 45mA (exclusive of load) |
| Output Transistors: | (1) NPN and (1) PNP sensor output transistorSensor outputs can sink or source up to 150mA (current limited)All outputs are continuously short circuit protected |
| Response Time: | Light/Dark state response = 100 microseconds |
| Hysteresis: | Minimal hysteresis promotes the detection between the backing material and the label depending on the settings. |
| Pushbutton Control: | Automatic setup routines based on web opacityOne push button setupPushing both buttons simultaneously inverts output |
| LED Light Source: | High intensity red LEDPulse modulated |
| Indicators: | Green LED flashes when AUTOSET routine is activated and stays illuminated when AUTOSET is completed.Red LED illuminates when sensor's output transistors are "ON". NOTE: The status of the output transistors can be inverted by pushing both buttons simultaneously. If Output LED flashes, a short circuit condition exists. |
| Light Immunity: | Responds to sensor’s pulse modulated light source, resulting in high immunity to most ambient light. |
| Ambient Temperature: | -40°C to 70°C (-40°F to 158°F) |
| Rugged Construction: | Chemical resistant, high thermoplastic PPS housingWaterproof ratings: NEMA 4 and IP66Conforms to heavy industry grade CE and UL requirements |
