GX-4S

Proximity sensors are types of switches with an electromagnetic field producing a centered magnetic flux that creates a current within an external metal target. The GX-4S is an inductive proximity switch used for detecting the presence or absence of a ferrous metal. The GX-4S utilizes a contactless energizing system, which requires no physical contact between itself and the metallic target. This means that the parts used do not require adjustments and the wear and tear of the contacts is eliminated.

The GX-4S operates on a fixed switching frequency and utilizes two different coil windings; one which creates an oscillator and the other that is energized with the reciprocating AC voltage. The capacitance of the target object, when placed in the field of the sensing coil, will determine the AC current through the energizing winding. This current will be compared to a set-point and, when it is exceeded, the output device is triggered. The output device can be either a single-contact switch, a continuous-contact switch, or a relay.

The GX-4S is easy to wire and can be used with multiple types of metallic targets. This makes it suitable for many applications such as detecting the presence of a metallic object, measuring its size, or regulating the motion or speed of a moving object. It can also be used as a sensing device to detect the location of a metallic object. Additionally, it can be used for measuring the distance between two metallic objects in an agricultural, industrial, or automotive setting.

Due to the design of the GX-4S, it is extremely reliable and can operate in a variety of harsh conditions. It is designed to reduce false triggering of the output devices and resists false triggering due to noise, electrical disturbances, temperature changes, and power supply fluctuations. Additionally, the GX-4S has a wide operating temperature range and is waterproof and dustproof.

The GX-4S is a versatile and reliable proximity switch. It is easy to install and can be used in a wide range of applications. With its high performance and reliability, it is ideal for industrial and automotive applications and is suitable for sensing the presence of any ferrous metal.
