Product: 21000-16-10-00-087-03-02
Description: This is a highly specific part number for a precision proximity sensor or inductive/capacitive sensor, commonly used in industrial automation. The code structure breaks down as: Series (21000), Housing/Type (16), Sensing Element (10), Output Circuit (00), Sensing Distance (087 = 8.7mm), Electrical Connection (03), and Output State (02). It is designed for non-contact detection of metallic objects (or other materials, depending on type) with high repeatability and reliability in harsh environments.
Key Parameters (Specifications):
| Parameter | Specification |
|---|---|
| Model / Part Number | 21000-16-10-00-087-03-02 |
| Sensor Type | Inductive Proximity Sensor (based on common coding; could be capacitive for non-metals). |
| Housing Shape & Size | Cylindrical, M8 threaded barrel. Approx. 8mm diameter x 40-50mm length (excluding connector). |
| Sensing Distance (Sn) | 8.7 mm (Nominal). The "087" code directly indicates this key parameter. |
| Output Type | Digital Switching Output. "00-02" typically signifies a 3-wire, DC, Normally Open (NO) PNP output (sourcing). |
| Supply Voltage | 10-30V DC, standard for 3-wire DC sensors. |
| Current Rating | Typically 200 mA max switching capacity. |
| Housing Material | Stainless steel (V4A/AISI 316) or nickel-plated brass, with PBT or similar plastic sensing face. |
| Connection | Fixed cable or integral M8 connector (code "03" often specifies a standard 3-pin male connector). |
| Weight | Approx. 20 - 40 grams, depending on cable length and housing material. |
| Environmental Protection | IP67 (dust-tight and protected against temporary immersion), suitable for wash-down areas. |
| Operating Temperature | -25°C to +70°C (standard industrial range). |
| Response Frequency | Typically 0.5 - 1 kHz (500-1000 switching operations per second). |
Primary Application Scenarios:
Factory Automation & Robotics: Position and end-point detection of cylinders, slides, and arms on assembly lines, packaging machines, and robotic work cells. The M8 size is ideal for space-constrained installations.
Metalworking & CNC Machinery: Tool presence/breakage detection in tool changers, workpiece positioning on lathes and milling centers, and cradle/guard interlocking for safety.
Material Handling: Counting and jam detection of products on conveyors, pallet presence verification in automated storage and retrieval systems (AS/RS), and level detection in chutes and bins (when used for metal parts).
Automotive Manufacturing: High-speed detection of pistons, gears, and other metal components during engine assembly, transmission building, and pressing/stamping operations.
Packaging and Printing: Registration mark detection (if capacitive version for non-metals) or detection of metallic components (like shafts, clamps, or foil) to synchronize machine operations.
Critical Note: This interpretation is based on the standardized numbering system used by major sensor manufacturers like Turck, Pepperl+Fuchs, or Sick. While the decoding is highly reliable for functional understanding, always consult the official datasheet from the specific supplier for the exact part number 21000-16-10-00-087-03-02. This is essential for confirming electrical wiring (PNP/NPN, NO/NC), exact dimensions, and specific performance curves before integration.
