HANDYLINK™
APPLICATION SPECIFICATION
1.0 SCOPE
This specification addresses the manufacturing techniques and end-usage considerations for Molex’s 0.8mm pitch HandyLink™ I/O
Connectors. The common contact interface used in this family of connectors consists of a flat pad mated to a radiussed edge on a
compression spring blade. The flat pad is enclosed by plastic in an over-molded receptacle housing which provides a sealed
ineterface to facilitate ingress protection. The compression spring blades are extremely durable and are capable of sustaining over
20,000 mating cycles. Two “passive” latches counteract the compression springs to keep the connector pairs mated but enable
simple disconnection by the end-user.
The customer is encouraged to contact Molex with any questions regarding the application of this product.

APPLICATION SPECIFICATION
4.0 MATING AND UN-MATING OF CONNECTORS
This section describes the preferred methods for mating and un-mating the HandyLink™ connectors.
4.1
Recommendations for Mating and Un-Mating
This connector system utilizes a “passive” latching feature. There is no button to press to latch or unlatch. To latch, simply push the
plug into the receptacle (the connectors are polarized to discourage improper mating). To unlatch, simply grip the plug body firmly and
pull it straight out of the receptacle.
4.2
Mating Alignment Tolerances
4.2.a 44828 Receptacle to 45339 or 45593 Plug Connectors
The HandyLink™ plug and receptacle have been appropriately designed and toleranced to be mated and unmated by hand. The
connectors’ alignment features are manufactured with clearances to allow axial mating mis-alignment, as illustrated in the Figure 1,
below:

Mating Alignment Tolerances (continued)
4.2.b 44828 Receptacle to 45560 Cradle Connectors
The HandyLink™ receptacle and cradle connectors’ alignment features are manufactured with clearances to allow some axial mating
mis-alignment as illustrated in the Figure 2, below:

Cradle Connector Axial
Alignment (units: mm)
NOTE: Mating misalignment may significantly influence the long-term durability of the connectors. The risk of housing wear diminishes
with increasing the accuracy of connector alignment.
