A12503RNCQE

Rotary switches are simple devices that provide a versatile, cost-effective solution for switching applications. There are many different types of rotary switches including, but not limited to, snap action, mechanical, and electronic. The A12503RNCQE is an electronic rotary switch designed for applications where increased reliability and accuracy are desirable, such as in medical and other safety-critical industries. This article will discuss the application field and working principle of the A12503RNCQE Rotary Switch.

The A12503RNCQE is a 12-position rotary switch that is suitable for a wide range of applications, from industrial automation and medical equipment to military and aerospace. It features a standard two-pin female socket connection and can be congruently installed in tight spaces. The switch is also dust and liquid resistant and is housed in a die-cast aluminum alloy body, providing a rugged and reliable design. The switch also has an IP65 rating, indicating that it is dust-tight and resistant to water jets and pressures.

The A12503RNCQE works by using an e-capacitance technology to detect the position of the rotary arm. This technology is based on the capacitance value between the arm and the switch\'s terminals, with each terminal having a different capacitance value when the arm is positioned at a different angle. When the rotary arm passes from one position to another, the capacitance value at the terminals changes and this change is detected by the switch\'s electronics. The switch then reports the new position of the arm, allowing for accurate safety control.

The A12503RNCQE is highly reliable and is capable of an ultra-long mechanical life. It features a contact force of 3N and a mechanical life of up to 3 million cycles. The switch also features a built-in ESD (electrostatic discharge) protection capability, which helps to protect connected components from potentially damaging electrostatic discharges. The switch can also be used as a safety interlock switch, allowing secure control of applications up to SIL3 level. Additionally, the A12503RNCQE is compatible with all major PLCs and can be used in a wide variety of industries, including automotive, medical, aerospace, military, and more.

The A12503RNCQE is a highly reliable and versatile electronic rotary switch suitable for a wide range of applications. Its advanced e-capacitance technology allows for accurate switching, while its rugged and dust-tight design ensures a long life and reliable operation. Its built-in ESD protection helps to protect connected components, and its compatibility with major PLCs makes it a suitable choice for a wide variety of industries.
