MEASUREMENT & INSPECTION HysteresisWindow-limit sensor models: 5 mm Fill-level control sensor models: 0 mm Output Response Time Selectable 1600, 400 or 100 milliseconds Minimum Window Size 20 mm Adjustments Sensing limits: TEACH-Mode programming of near and far limits may be set using the TEACH push button. Sensor configuration: Output response time and temperature compensation mode may be set using the Speed push button. Factory default settings: 400 milliseconds output response timeTemperature compensation enabled IndicatorsGreen Power On LED: Indicates power is ON Red Signal LED : Indicates target is within sensing range, and the condition of the received signal. Output indicator (bicolor Yellow/Red): Indicates output status or TEACH mode Response indicator (bicolor Yellow/Red): Indicates output response time selection ConstructionTransducer: Ceramic/Epoxy composite Housing: ABS Membrane Switch: Polyester Environmental Rating Leakproof design is rated IEC IP67; NEMA 6P Connections 2 m or 9 m shielded 5-conductor (with
industrial drain) PVC jacketed attached cable, or 5-pin Micro-style quick-disconnect or 5-pin Mini-style quick-disconnect. QD cables are ordered separately. See pages 386 and 388. Operating ConditionsTemperature: -20° to +70° C Relative humidity: 100% Vibration and Mechanical Shock All models meet Mil Std. 202F requirements. Method 201A (vibration: 10 to 60Hz max., double amplitude 0.06", maximum acceleration 10G). Also meets IEC 947-5-2 requirements: 30G 11 milliseconds duration, half sine wave Temperature Warmup Drift Less than 1.0% of sensing distance upon power-up with Temperature Compensation enabled Application Notes Objects passing inside the specified minimum sensing distance (200 mm) may produce a false response Certifications Approvals in process.
