Proximity Sensor


Overview

Infrared proximity sensor made by Sharp. Part # GP2Y0A21YK has an analog output that varies from 3.1V at 10cm to 0.4V at 80cm. The sensor has a Japanese Solderless Terminal (JST) Connector. We recommend purchasing the related pigtail below or soldering wires directly to the back of the module.

Proximity Sensor

Proximity Sensor are available in models using high-frequency oscillation to detect ferrous and non-ferrous metal objects and in capacitive models to detect non-metal objects. Models are available with environment resistance, heat resistance, resistance to chemicals, and resistance to water.

Cylinderical

These Proximity Sensors use high-frequency oscillation. They resist heat, chemicals, and water better than Rectangular Sensors. They are available in both shielded and unshielded models.

Capacitive Sensors

Capacitive sensors can be used to detect metal objects as well as nearly all other materials. These sensors are often used in applications including level, flow control for detection of liquids, grains and powders.

Standard Capacitive Sensor Product features:

  • 12, 18 and 30 mm cylindrical styles of stainless steel or plastic housings
  • 5mm thin rectangular and long range 80 mm x 80 mm x 40 mm styles
  • Sensor outputs of 3-wire DC and NAMUR output types
  • Models with hazardous area approvals

 

Magnetic Field Sensors

Our magnetic field sensor selection consists of the M12 housing style for traditional magnetic detection applications. Also offered is a non-contact, piston detection sensor for use with steel hydraulic cylinders. These magnetic sensors offer reliable piston magnet detection and are easily mounted, without the need for mounting slots or holes in the cylinder.
