Product details

20-Circuit SL 70066 Receptacle Housing

This housing uses crimp termination — the installer selects the wire gauge and crimp terminal separately. The free-hanging (in-line) mounting style means no PCB footprint is needed; the connector mates with a pin header soldered to the board or with another in-line housing.

Mating Half and Compatibility

The 0050579020 mates with a 20-circuit, single-row, 0.100" pitch SL-series pin header (male). The header can be either vertical or right-angle, through-hole or surface-mount, depending on the board layout. The keying feature of the SL series prevents mismating with different circuit-count housings. Because the housing is unsealed and not rated for washdown, it is intended for dry, interior environments where the operating temperature stays within -40°C to 105°C.
