Proximity Switch And Sensor

Proximity Switch And Sensor detects the presence of nearby objects without any physical contact. Different proximity sensor targets demand different sensors. For example, a capacitive or photoelectric sensor might be suitable for a plastic target, an inductive proximity sensor requires a metal target. They are highly reliable and have a long functional life because of the absence of mechanical parts and lack of physical contact between sensor and the sensed object. Proximity sensors are also used in machine vibration monitoring to measure the variation in distance between a shaft and its support bearing.

We are an manufacturer and supplier of Magnetic Proximity Switches. The "reed" contact of the switch changes when operating magnet passes-by within the sensing range of the switch. The magnetic pickup will generate signal when geared wheel rotates.

These switches required a magnet for there operation. The magnet is supplied with the switch.The reed element which is sealed in the switch operates when the magnet passes nearby.

Salient Features:

  • Non contact operation
  • Potential free contacts suitable for low voltage
  • High Operating distance upto 25mm
  • Totally enclosed - Robust - cast Al/plastic enclosure for switch as well as magnet.IP 67
  • A special stay - put type of switch is developed which can be used to sense direction

    Capacitive Proximity Switch and Sensor works when the object enters in the sensing zone of the switch, capacitance between two plates of capacitor (one plate is represented by electrode at sensing face of the switch and another by all surrounding material which is connected to the earth) changes. As soon as capacitance value crosses preset level, oscillator starts. This change is detected and resulted in an output signal.

    Sensitivity Adjustment:


    Capacitive proximity switch senses all metals and non-metals. The sensitivity of switch also depends on the surrounding environment. Therefore each switch is to be adjusted at the site to get best results. A multi turn potentiometer is to be adjusted to increase or decrease the sensitivity. Slowly turn the potentiometer clockwise to increase the sensitivity. Extreme sensitivity is achieved when load and ‘led lamp’ remains continuously ‘on’ irrespective of object. This is maximum limit of the sensitivity.Reduce the sensitivity by at least 2-3 turns than maximum value. When switch is used for controlling level, sensitivity is to be set to minimum applicable so as to avoid false tripping by thin layer of powder deposited on the switch.
