MWDM2L-21PSB Glenair 21-Position Micro-D Plug
Mfr. Part #: MWDM2L-21PSB
Manufacturer: Glenair
Series: MWDM Micro-D
Package/Case: 21-Position Metal-Shell Micro-D Plug
Description: 21-position Micro-D plug with male solder-cup contacts, nickel-plated aluminum shell and through-hole mounting hardware
The Glenair MWDM2L-21PSB is a 21-position Micro-D plug featuring male pin contacts and solder-cup termination. It combines a high-density 0.050-inch contact arrangement, nickel-plated aluminum shell, gold-plated beryllium-copper contacts and a fluorosilicone interfacial seal.
Designed for aerospace, defense, industrial and telecommunications equipment, the MWDM2L-21PSB provides a compact signal interface for systems requiring more circuits than a 15-position Micro-D without moving to a larger 25- or 31-position configuration.
