Product catalog summary

Overview: The Series DS Tilt Switch is designed for high reliability and environmental protection, featuring a photo interrupter mechanism and sealed construction. It is suitable for automatic soldering and cleaning processes, and its compact size allows for high-density mounting.

Distinctive Characteristics: The switch operates with a 360° rotation capability and is triggered when tilted beyond ±30° or ±10° of the horizontal, depending on the model. It is environmentally friendly, containing no mercury, and offers high contact reliability.

DSA Switch Specifications:

Mechanical & Electrical: Single Pole Single Throw (ON-OFF), with an operating range of 10° to 170° ON and 190° to 350° OFF. It supports a resistive load of 0.1A @ 12V DC, with a contact resistance of 100 milliohms max and insulation resistance of 50 megohms min @ 250V DC.
Environmental: Operating temperature range is –10°C to +70°C, with a storage range of –25°C to +85°C. It can withstand 90% humidity for 96 hours at 40°C.
Materials: Housing is made of PBT, with brass contact balls and terminals plated with silver.

DSB Switch Specifications:

Mechanical & Electrical: Offers a mechanical and electrical life of 1,000,000 operations. Operating temperature range is –25°C to +80°C, with a storage range of –30°C to +85°C.
Environmental: Can endure 85% humidity for 500 hours at +85°C, and withstands vibration and shock as specified.
Materials: Housing and base are made of glass fiber reinforced polyamide, with phosphor bronze terminals plated with tin.

Mounting and Processing: The switch can be mounted with a PCB adaptor, and supports wave and manual soldering. Automated cleaning should use an alcohol-based solution.

Design Considerations: Avoid installing near vibration sources or exposing to magnetic fields. Ensure the switch is mounted at an angle less than ±3° from the mounting surface.
