13-position MTA-100 strain relief cover
The 1-643075-3 is a 13-position closed-end strain relief cover from the TE Connectivity AMP Connectors MTA-100 series, designed for use with MTA-100 connectors.
Position count and series fit
The 13-position 1-643075-3 is the strain relief cover for the MTA-100 connector family — the position count matches the circuit count of the mating connector, so a 13-circuit MTA-100 header or receptacle uses this cover.
