Proximity Sensor Overview

This document provides detailed technical specifications and descriptions for various types of proximity sensors, focusing primarily on inductive and capacitive sensors with different form factors and installation methods.

1. Sensor Types and Models

• Inductive Proximity Sensors: Standard, square, small square, and micro square types.
• Capacitive Proximity Sensors: Cylindrical types with adjustable detection distances.
• Output Types: NPN Normally Closed (NC), NPN Normally Open (NO), PNP Normally Closed (PC), PNP Normally Open (PO).

2. Key Specifications

• Detection Distance: Ranges from 1.5mm to 25mm depending on model and type.
• Working Voltage: Typically 5-30V DC, with variants labeled as A (10-30V) and B (5-30V).
• Maximum Load Current: Specified per model, important for ensuring compatibility with connected devices.
• Switching Frequency: Indicates sensor response speed.
• Leakage Current and Residual Voltage: Provided to assess sensor electrical characteristics.
• Working Temperature and Protection Grade: Sensors include options for high temperature and low temperature resistance, with protection circuits and IP ratings for environmental robustness.

3. Construction and Materials

• Sensor housings are made from materials such as stainless steel, nickel copper alloy, resin, and Teflon shells.
• Induction surfaces vary by sensor type and are designed for metal detection or capacitive sensing.
• Plastic nuts and toothed gaskets are used for mounting and securing sensors, with various sizes specified (e.g., opposite side 12 T=3, 17 T=4, 24 T=4, 36 T=5).

4. Installation Methods

• Embedding (A): Sensors designed to be embedded within machinery or surfaces.
• Non-embedding (B): Sensors mounted externally without embedding.
• Connection modes include cable type (Z) and plug-in (Y).

5. Electrical Connection and Circuit Diagrams

• Wiring typically involves four wires: Brown (power), Blue (ground), Black and White (switching outputs).
• Circuit diagrams for both inductive and capacitive sensors are provided, illustrating typical load connections and switching outputs.

6. Protection and Safety Features

• Short circuit protection is standard across sensor models.
• Some models include analog outputs (current or voltage) for variable sensing applications.

7. Additional Notes and Coding

• Model codes include letters indicating features such as detection distance (e.g., 5mm, 10mm), installation mode (A or B), output type (NC, NO, PC, PO), and special characteristics (e.g., R for standard, L for enhanced, G for high temperature).
• Series classification includes L for electric sensors and C for capacitive sensors.
