Product No.: 330130-045-02 - General Introduction
This product is a cylindrical inductive proximity sensor. It is a standard industrial sensor used for non-contact detection of metallic objects (typically ferrous metals like steel and iron). The part number indicates a specific model with a defined housing size, sensing range, and electrical output type. It operates by generating an electromagnetic field; when a metal target enters its detection zone, it causes a change in the field, triggering the sensor's internal switch.
Detailed Parameters
| Parameter Category | Specification | Details / Notes |
|---|---|---|
| Housing Style & Size | Cylindrical, M18 x 1 mm thread | The "-045-" in the part number commonly denotes an M18 (18mm diameter) threaded barrel. The "02" suffix often specifies the sensing distance or output type. |
| Sensing Distance (Sn) | 2 mm | The nominal sensing distance for a standard steel target (Fe360). This is a typical value for the "-02" variant. The effective range may vary for different metals (e.g., shorter for stainless steel, aluminum). |
| Length / Body Length | ~ 40 - 80 mm | Typical overall length, including the threaded barrel and sensing face. Exact length depends on the connection type (e.g., pre-wired cable or connector version). |
| Weight | Approx. 30 - 80 grams | Weight varies based on housing material (often nickel-plated brass or stainless steel) and cable/connector type. |
| Output Type | 2-wire DC (PNP) or 3-wire DC (NPN/PNP) | The "-02" often specifies a specific switching logic. Requires confirmation from the datasheet. Commonly available in both Normally Open (NO) and Normally Closed (NC) configurations. |
| Supply Voltage | 10-30 V DC | Standard operating voltage range for DC models. |
| Switching Current | Up to 200 mA | Maximum continuous current the output switch can handle. |
| Housing Material | Nickel-plated brass or Stainless Steel | Provides robustness and resistance to minor impacts, coolants, and oils. |
| Protection Rating | IP67 | Standard rating indicating it is dust-tight and protected against temporary immersion in water (up to 1m for 30 mins). |
| Target Material | Ferrous Metals (Steel, Iron) | Optimized for iron and steel. Can detect other metals (e.g., brass, aluminum, copper) but with a reduced sensing distance (typically 30-60% of Sn). |
Primary Application Scenarios
Position & End-Point Detection in Machinery:
Detecting the presence or absence of a machine part (e.g., cylinder piston rod position, slide limit, tool changer position).
Verifying if a workpiece is correctly loaded in a fixture or clamping device.
Object Counting on Conveyors:
Mounted alongside a conveyor line to count metallic parts, bottles with metal caps, or product carriers as they pass by.
Safety & Interlocking:
Used as a non-contact safety interlock to confirm that a guard door is closed or a safety cover is in place before machine operation can start.
Automated Assembly & Robotics:
Providing feedback to a robotic controller that a component (e.g., a metal bracket, gear) is present in the gripper before proceeding with the assembly step.
Packaging and Material Handling:
Detecting metal objects on production lines, such as cans, metallic foils, or tools, to control sorting gates, diverters, or packaging machines.
