Capacitive Sensors

Overview

We are Capacitive Sensors Suppliers, Distributors & Importers in Mumbai, India. The CARLO GAVAZZI Capacitive Sensor is one type of proximity sensor used in the detection of solid, fluid, or granulated substances. Working on the principle of change in capacitance caused by a target object coming nearer to the sensor, it finds wide applicability in many industrial uses and agricultural applications where materials to be recognized may be grains or fluids. The capacitive sensors from CARLO GAVAZZI are designed for detecting levels of solids, fluids, or granulated substances. These sensors have a lot of applications in various types of industries and, more precisely, in the agricultural sector to determine grains, fluids, etc.

Capacitive Sensors

Operation Modes

  • CA30CLN12MU10M: After detecting the target, the relay holds for a set time (0-10 minutes) before releasing.
  • CA30CLN12MT: The relay remains ON until the target is detected, then immediately releases.
  • CA30CLN12MV10M: Time delay starts when power is applied, and the relay operates after the set time has expired.

Wiring Diagram

  • Supply Voltage: 24-230V AC/DC.
  • Wires: Brown (BN) and Blue (BU) for power supply, Grey (GR) for common, Black (BK) for normally open, and White (WH) for normally closed.

Applications

Ideal for detecting materials like grains, fluids, and more, especially useful in agricultural and industrial environments.

Benefits of Capacitive Sensor

  • Versatility: With the adjustable sensing range and multi-voltage capability in the Capacitive Sensors, this sensor can be applied to a wide range of uses, such as detecting levels both in liquid and solid materials.
  • Ease of Use: Easy setup to satisfy specific needs due to precise tuning through adjustable time delay and sensing distance.
  • Durability: With rugged construction and high protection ratings (IP67), this sensor withstands the harshest environments in industry for years of reliable service.
  • Direct Load Driving: The SPDT relay output can drive the connected devices directly to make the design of the system very simple

Importance

CARLO GAVAZZI Capacitive Sensors are of especially importance in applications where target materials may not be detected by other sensor technologies due to the material properties itself, or when it is essential that detection process does not fail as a result: It is what enables a robot to work in variety of environments and conditions and lies at the core of any automation system
