MWDM2L-31SSB Glenair 31-Position Micro-D Receptacle
Mfr. Part #: MWDM2L-31SSB
Manufacturer: Glenair
Series: MWDM2L Micro-D
Package/Case: 31-Position Metal-Shell Micro-D Receptacle
Description: 31-position Micro-D receptacle with female solder-cup contacts, nickel-plated aluminum shell and through-hole mounting hardware
The Glenair MWDM2L-31SSB is a 31-position Micro-D receptacle with female socket contacts and solder-cup termination. It combines a high-density 0.050-inch contact arrangement, nickel-plated aluminum-alloy shell and gold-plated contacts in a compact two-row package.
Designed for aerospace, military, industrial and telecommunications equipment, the MWDM2L-31SSB provides 31 signal or low-current power connections where a conventional D-sub connector would require excessive panel space and weight.

Frequently Asked Questions
What type of connector is the MWDM2L-31SSB?
It is a two-row, 31-position Glenair Micro-D receptacle with female socket contacts and solder-cup termination.
What wire size does the MWDM2L-31SSB support?
It is primarily specified for #26 AWG wire. Some current distributor records list 24–26 AWG compatibility, so the exact Glenair drawing should be checked before selecting the conductor.
What are its main electrical ratings?
The connector is rated for 3A per contact, 600VAC dielectric withstand at sea level, 5,000MΩ minimum insulation resistance and 8mΩ maximum contact resistance.
What connector mates with the MWDM2L-31SSB?
It requires a compatible 31-position Micro-D plug with male pins, such as an appropriate MWDM2L-31PSB configuration. The mounting hardware must also match.
Is the MWDM2L-31SSB a qualified MIL-DTL-83513 connector?
It is a Glenair commercial MWDM part number. It should not be described as a QPL MIL-DTL-83513 connector unless current Glenair documentation explicitly confirms that status.
