Proximity Inductive Switch

Proximity Inductive Switches are used for non-contact metal sensing. Being contactless sensors these can be used for position sensing, speed measurement, counting, etc. These inductive proximity sensors can be used in extreme conditions, such as oily, dusty, corrosive environment. Proximity Inductive Switches are used from automobile industries to steel industries, from CNC/NC machines to material handling equipments, process automation, conveyor systems, packaging machines.

Inductive proximity sensors can be used for position sensing, speed measurement, counting & in conditions such as oily. dusty, corrosive environment. These inductive sensors applications are in Automobile, Steel Industries, CNC/NC machines, Conveyor systems, Packaging machines etc.

These 3 wire DC sensors are with NPN or PNP transistorised output and the load is connected in parallel.

These Sensors are designed to work as solid state DC limit switches. The Sensors are connected directly in series with a load and have a bridge rectifier so they are not polarity conscious. The circuit is such that, when in off state, it allows very low current to flow through the load. However, a output load (such as relay) should be chosen, considering the voltage drop across the switch in the ON state. These sensors find wide application in electrical control circuits and PLC's.

These Sensors are designed to provide better alternative to conventional limit Switches / micro switches. These are epoxy potted similar to other types of sensors to render IP67 protection and hence are suitable even in underwater applications. The load (AC Contactor / AC Relay / Solenoid Coil) is to be connected in series with the switch.

* In sizes M30 & above

These are constructed in Rectangular, T type, Slot type, Pentagonal and Block types senors The technical specifications are similar to standard cylindrical sensors and are available in 3 wire DC & 2 wire AC types.

Proximity Sensors can be used :

• To drive DC relay.
• To drive DC contactor (ask for load current 500 mA).
• To drive AC relay/AC contactor.
• Can be coupled directly to any PLC / DCS / Logic Circuits.
• Can be used as an input for a Digital Counter/RPM Indicator etc.

We offer high quality capacitive sensors that are used in various industrial applications to measure or detect different physical quantities. These capacitive proximity switches are manufactured using state-of-the-art technologies that guarantees accurate reading with highest level of precision.

Capacitive Proximity Sensors is designed to detect and react to any object which moves into the operating zone. The sensors contains an oscillator. The capacitance of this oscillator is linked with the sensing face and when any object moves into the operating zone, its capacitance activates the oscillator. The sensors can detect conductive as well as non conductive material. It is advisable to have an object with permitivity more than one. The conductive objects are generally to be earthed for better results.
