Proximity Switches

Protocontrol make Proximity Switches that serve as a basic block of automation. Find application for Position - Speed - Direction - Revolution -Liner Speed measurement.

We are proximity switches manufacturer and also offering sensing solutions for all applications. You specify the requirement and we will help you to select suitable sensor from more than 2600 varieties we have. Every proximity sensor switches are designed for industrial application.

Most of our proximity carries CE mark.

Capacitive Proximity Switches (CPS)   Send Enquiry

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.

• Three Wire Switches
• Two Wire Ac Switches

Salient Feature of Capacitive Proximity Switches (CPS)

1. Hysteresis : 5-20 % of set sensitivity
2. Grade of Protection : IP 65 / IP67
3. Enclosure : Metallic ( Nickel plated brass) / Stainless Steel / Plastic.
4. LED Indication : Provided.

Sensitivity Adjustment

Capacitive Proximity Switch senses all metals and nonmetals. The sensitivity of switch also depends on the surrounding environment. Therefore each switch is to be adjusted at 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 max. limit of the sensitivity. Reduce the sensitivity by at least 2-3 turns than max. 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.
