23SM13

Snap Action, Limit Switches

The 23SM13 is a snap action, limit switch; a small yet effective mechanical switch used in construction of various circuit system configurations. Snap action switches are commonly used as control signals to complex automated systems, or as a form of interface between sensor systems and mechanics, or as a raw point of access in which control signals are fed into the various systems. The 23SM13 specializes in precisely controlling the limit of a butterfly valve, the limit of a system to maintain consistent performance or the maximum breaking point of a machine or system.

The 23SM13, much like other limit switches, are built from an array of mechanical parts, with each part having an extensive purpose, from the casing to each individual switch within. The main body of the limit switch is constructed with an enclosed stainless steel housing, offering maximum environmental protection for the internal mechanism. The internal mechanism is made up of a pair of hardened 1/4 inch steel buttons and a durable elastic material, such as rubber or plastic. The steel buttons are connected to the elastic material, allowing them to move freely in order to close or open the contact points between them, thus triggering the switch.

The 23SM13 offers a range of optional features including adjustable deadbands, adjustable limit stop and adjustable preload caps. The adjustable deadbands feature results in a smoother switching operation, while the adjustable limit stop allows the user to set the exact limit of the switch. The adjustable preload caps provide a preset force to open or close the switch, ensuring that the limit switch remains in position when the switch is activated. Alternatively, the limit switch may be installed with the optional dual-point switch, which allows two separate contact points to be connected at the same time, thus providing an additional point of access.

The 23SM13 is available in two different models, the standard 23SM13-10 and the 23SM13-20. The 23SM13-10 model is designed for light duty, low voltage applications, while the 23SM13-20 model is designed for high voltage applications, such as motors, pumps, valves and electric fences. Both models are designed for use with a range of AC and DC electrical systems, with a maximum voltage rating of 125V AC/ 250V DC. The 23SM13 is also available in a range of termination styles and slot depths, with simple push on terminals, solder terminals and Universal Coil Terminal (UCT) compatible options.

The limit switch is also equipped with an integral connection sleeve, which facilitates the installation and maintenance of the unit. The integral connection sleeve provides an efficient way to connect the switch to the existing wiring, and also allows the switch to be quickly disconnected if necessary. The 23SM13 also provides a range of mounting options, with direct surface mounting, L or T shaped attachment or panel mounting options.

The 23SM13 is a robust and reliable limit switch, offering a range of features and protection options to facilitate its operation in a range of operating conditions. The unit is designed to be economical yet durable and provides an easy to mount solution to circuit systems of various complexities.
