Proximity Switches

We are Manufacturer, Supplier, Exporter of Proximity Switches and our setup is situated in Pune, Maharashtra, India.

Sai Control System has been manufacturing the wide range of high quality proximity switches over two decades. These switches are used in all areas of control & automation such as machine tools, packaging, injection molding, automobile industries, process industries, textile industries, pharmaceutical, forging and other automated systems.

A proximity switch is a tool which produce a reversing the action devoid of any actual connection. Proximity Switches / Sensors retort to objects that enter in between the active area of their effected perceiving spheres.

Proximity Switches / Sensors / Sensors perceive the existence of metallic / nonmetallic items by means of a high density electric field proximity switch which consists of a sensor circuit in the driver circuit. The purpose of the sensor circuit is to inspect any adjacent objects when a signal is received from the sensor circuit. Proximity Switches / Sensors , when come in contact/ approach an object at a certain distance, they open or close an electrical circuit. Maximum utilization of Proximity Switches / Sensors is done for automation, security systems, manufacturing equipment and in robotics.

Proximity Switches / Sensors are utilized in various types of manufacturing techniques. In machinery, Proximity Switches / Sensors are used to calculate the location of machine components. Proximity Switches / Sensors are used also used in applications like identifying the door opening, security systems. Etc. In robotics, Proximity Switches / Sensors can track a robot or its material’s immediacy to objects and manage it subsequently.

Operating Temperature : Operating Temperature of Proximity Switches is 0 to 55° C. Temperature up to 100°. C can be manufactured on request.

Protections : AC Proximity Switches are protected against transient and surges. DC switches are protected against short circuit and reverse polarity.

Switching Hysteresis : This is the difference between Switch ON and Switch OFF point of the switch. This is adjusted within 5% to 15% of the specified sensing distance.
