100mA @ 50V DC
80 milliohms maximum for circuit; 30 milliohms maximum for contact point
1,000 megohms minimum @ 250V DC
250V AC minimum for 1 minute minimum
20,000 detent operations minimum
20,000 detent operations minimum
Note: A detent operation is one actuator position operation or stepping.
20,000 detent operations = 1,250 cycles for hexadecimal devices or 2,000 cycles for decimal
devices. A cycle is one 360° rotation.

Processing
Soldering:
Reflow Soldering: See Profile B in Supplement section.
Note: During Reflow Soldering process, set the switch to the following position:
ND3FR10, ND3FR16, ND3KR10, ND3KR16: 0 position;
ND3FC10, ND3KC10: 7 position; ND3FC16, ND3KC16: F position.
Manual Soldering: See Profile B in Supplement section.

Automated cleaning. See Cleaning Specifications in Supplement section.
UL94V-0 rated housing & base
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.
