Infrared Optical Sensor with 8 ft. cable
The Infrared Optical Sensor (IRS) is a high-performance sensor designed for precise speed measurements in industrial applications. Encased in a threaded 303 stainless steel tube, the sensor operates effectively within a 0.5-inch range from the target, detecting contrasts or beam interruptions as small as 0.039 inches. Two models are available: IRS-P, equipped with a stereo plug for compatibility with Monarch handheld tachometers, and IRS-W, featuring tinned wires for integration with Monarch panel instruments. To ensure accurate measurements, a contrasting color target on the rotating part is required, with recommended options including wax crayon-coated shafts, labeled gear teeth, or other marked objects. The sensor, with a red/green LED On-Target Indicator, must be properly mounted to achieve optimal results. It operates with a speed range of 1-1,000,000 RPM, utilizing an infrared LED for illumination, and requires a power supply of 3.3 – 15 V dc @ 40mA.
1. Construction and Material:
– Threaded 303 stainless steel tube construction ensures durability and longevity.
– Infrared Optical Sensor is supplied with a mounting bracket and two M16 jam nuts for easy installation.
2. Operating Range and Target Detection:
– Effective operation within a range of up to 0.5 inches [12 mm] from the target.
– Capable of detecting small objects, slots, bolt heads, and keys with a minimum size of 0.039 inches [1 mm].
3. Models and Compatibility:
– IRS-P model with a stereo plug designed for seamless integration with Monarch handheld tachometers and stroboscopes.
– IRS-W model with tinned wires compatible with Monarch panel instruments, including ACT Series and DataChart™ devices.
4. Power Requirements:
– Infrared Optical Sensor requires a power supply of 3.3 – 15 V dc @ 40mA for efficient operation.
5. On-Target Indicator:
– Features a red/green LED On-Target Indicator located on the wire end cap.
– Solid green LED indicates powered status, while an amber LED signifies being on target.
6. Speed Range:
– Impressive speed measurement capability ranging from 1 to 1,000,000 RPM for versatile industrial applications.
7. Illumination Technology:
– Utilizes an infrared LED for illumination, providing a non-visible light source ideal for diverse working environments.
8. Operating Temperature and Humidity:
– Can operate within a wide temperature range from -40° to 185° F [-40° to 85° C].
– Humidity tolerance up to a maximum relative humidity of 80%, decreasing linearly to 50% at 104 °F [40 °C]; humidity must be non-condensing.
9. Connection and Cable Length:
– Available with a 1/8 in. [3.5 mm] male stereo plug (IRS-P) or tinned wires (IRS-W) for convenient connection.
– Comes with an 8 ft. [2.4 m] cable length for versatile installation options.
10. Dimensions:
– Threaded tube dimensions: 2.90 in. x 0.625 in. diameter [M16 x 1.5 x 74 mm] long.
11. Preparation and Target Recommendations:
– Requires a contrasting color target on the rotating part for accurate measurements.
– Recommended target options include wax crayon-coated shafts, labeled gear teeth, or other marked objects.
12. Safety Considerations:
– Caution regarding centrifugal force at high speeds; all targets must be securely fastened to shafts.
– Plexiglass sheet protection (minimum 0.5 inch [12 mm] thick) recommended for operator safety.
13. CE Compliance:
– To achieve full CE compliance, the supplied ferrite must be attached around the plug/wire end of the cable.
14. Ambient Lighting Sensitivity:
– Sensitive to ambient lighting conditions; shielding may be required in the presence of fluorescent lamps or sunlight for accurate readings.
15. Optional Accessories:
– Optional 25 ft. [7.6 mm] extension cable (EC-25P) available for extended reach, featuring a female socket for the plug on one end and a 1/8 inch [3.5 mm] male stereo plug on the other.
The IRS Infrared Sensor with an 8 ft. cable is designed for applications demanding precise high-speed RPM measurement. It excels in situations with very high-speed equipment or those that provide only contrasting light and dark surfaces. This sensor is suitable for use in various industrial applications.
