8mm Process Sealed SMT DIP Rotaries

Series ND3

General Specifications

Electrical Capacity (Resistive Load)

Switching Rating:

100mA @ 5V DC

Nonswitching Rating:

100mA @ 50V DC

Other Ratings

Contact Resistance:

80 milliohms maximum for circuit; 30 milliohms maximum for contact point

Insulation Resistance:

1,000 megohms minimum @ 250V DC

Dielectric Strength:

250V AC minimum for 1 minute minimum

Mechanical Life:

UL Recognition

or CSA Certification:

The ND3 Series rotaries have not been tested for UL recognition or CSA certification.

These switches are designed for use in a low-voltage, low-current, logic-level circuit.

When used as intended in a logic-level circuit, the results do not produce hazardous energy.
