COMPLETE SHIELDING SYSTEMS

Switchcraft also offers shielded DIN receptacles for use with shielded molded cable assemblies. Together they provide a valuable design tool to supress EMI interference to permit you to meet strict requirements of FCC Docket 20780.

ORDERING

1. Order by part number
2. For special order items, contact Switchcraft with details.

SPECIFYING NOTE: See Connector Section for mating receptacles.

Switchcraft DIN molded cable assemblies meet increased demand for modern, field-tested connections for a wide range of electrical/electronic applications. Connectors are DIN (Deutsch Industrie Norm) circular type, male or female (locking or non-locking) with 3 to 8 pins/contacts. Units are molded and protected with a rugged handle, and are fully shielded and equipped with advance design cable relief. Switchcraft cable assemblies and mating receptacles adhere to strict requirements of FCC Docket 20780 and offer fully shielded links for data and instrumentation applications of all kinds.

SHIELDING EFFECTIVENESS

Effectiveness of shielding is frequency-dependent; as frequency increases, more shielding is required to maintain comparable shielding effectiveness. The chart below delineates shielding effectiveness with molded cable assemblies with 100% foil shield cables and shielded DIN connectors.

Frequency Range MHz	Shielding Effectiveness, dB
30-500	-30
60-400	-20
500-800	-10

ELECTRICAL

Contact Resistance: Cord Plugs and Receptacles .010 ohms, contact spring/pin; .030 ohms, ground clip/shell. Control and Switching Receptacles: .015 ohms, contact spring/pin; .020 ohms, switch contacts.

Dielectric Withstanding Voltage: 500 V (rms).
Leakage Resistance: 10⁵ M(omega)

MECHANICAL

Life: 5000 cycles
