Product catalog summary

Overview: This document provides comprehensive details on NKK's SmartSwitchTM OLED and LCD pushbuttons and displays, covering technical specifications, operational guidelines, and handling precautions for various programmable switch models.

SmartSwitchTM OLED Pushbutton: The OLED pushbutton features a high-contrast display with a 180° viewing angle, supporting 65,536 colors in 16-bit mode. It has a long operational life of up to 60,000 hours and consumes 3.8mA of power. The switch is dust-tight and designed for style.

Specifications: The document includes absolute maximum ratings, recommended operating conditions, and detailed electrical and mechanical specifications. The OLED display operates in passive matrix mode with a pixel format of 64RGB x 48 pixels.

Switch Specifications: The switches are designed for high reliability with a minimum of three million actuations, detailing electrical capacity, contact resistance, insulation resistance, and mechanical endurance.

Display Characteristics: Optical characteristics include luminosity and color coordinates for various colors, with a contrast ratio higher than traditional LCDs.

Handling and Storage Precautions: Emphasizes the electrostatic sensitivity of OLED devices, providing guidelines for safe handling and storage to prevent damage.

Timing Specifications: Detailed timing diagrams and state transition sequences for switch and display operations are provided.

Critical Information: Highlights the importance of following recommended power and signal sequences to avoid OLED unit damage, with part numbers and descriptions for easy identification and ordering.

SmartSwitch OLED Rocker Specifications: Features a monochrome OLED display with a resolution of 96 x 64 pixels, a wide viewing angle of 180°, and a large 0.92” display. It conforms to IP64 standards for dust and splash resistance and has a long operating life of 52,000 hours at 30% brightness.

Procedures: Handling procedures emphasize the sensitivity of OLED devices to electrostatic discharge, recommending power and signal voltage sequences to prevent damage. Cleaning should be done with a dry or damp cloth using a neutral cleanser.

Storage: OLED devices should be stored in original containers, away from direct sunlight, static electricity, extreme temperatures, high humidity, and chemical contamination.

Operating Conditions: Recommended operating conditions include a supply voltage for logic/interface of 2.7V to 2.9V and for drive of 14.5V to 15.5V, with an operating temperature range of -20°C to +70°C.

Electrical Specifications: The switch specifications include a single pole three throw circuit with a contact resistance of 200 milliohms maximum and an insulation resistance of 500 megohms minimum at 250V DC.

Recommendations: To ensure uniform pixel brightness over time, it is recommended to operate the OLED unit so that all pixels are used consistently. Guidelines for panel mounting emphasize even gasket positioning and avoiding excessive force during installation.

Additional Features: The SmartSwitch OLED Rocker supports serial communications protocol (SPI) for commands and data, including a graphic display data RAM and a light decoder for display control and screen saver functions.

SmartSwitchTM LCD 64 x 32 Pushbutton Overview: Highlights its compact size, high resolution, and low energy consumption, with information on switch and display specifications, pin configurations, and operational guidelines.

Switch Specifications: The switch is a SPST momentary ON type with gold contacts and straight PC terminals, with a mechanical and electrical endurance of 3,000,000 operations minimum.
