Overview of the Omron A165SN Selector Switch
The Omron A165SN series features a knob-type selector switch with a detachable, cylindrical 16-diameter design. Emphasizing its compact construction, it follows the modular approach of the A16-series pushbuttons, ensuring effortless integration and maintenance. This switch has been engineered to be versatile for different applications by allowing the use of common contacts for both standard and micro loads.
Design and Features
The miniature design with a depth of only 28.5 mm enables it to fit in tight spaces without compromising functionality. Enhanced durability is present due to its oil-resistant properties and an IP65 rating, confirming its resilience against ingress of dust and low-pressure water jets. Meeting the standards of EN60947-5-1, it ensures compliance with European safety regulations for control circuit devices and switching elements.
No matter the application, compatibility is a highlight, featuring a variety of models for different electrical setups. The series offers square, rectangular, and round shapes for easier alignment with existing systems and preferences. Models come with solder terminals for straightforward wiring, or screw-less clamp connectors for when quick deployment is needed.
Variants and Configurations
Different model numbers correspond to an array of configurations. Each set includes a selector switch, lamp (on lighted models), and switch. Users can select from various positions, colors, and light sources including non-lighted, 24-volt LEDs, and models with a voltage reduction feature. Terminal types also vary, with solder terminals only available with 100-V models, while screw-less clamp connectors lack a voltage reduction unit. Importantly, PCB terminals are exclusive to 2-notch models.
Contact configurations are either single pole double throw (SPDT) or double pole double throw (DPDT) types, with lighted 3-notch models and screw-less clamp connectors only offering DPDT. Customization extends to the selection of operating voltage and rated voltage, adhering to the specific needs of assorted electrical environments.
