1.50 mm Pitch Pico-Lock Crimp Housings - 504051 Series
The Molex 1.50 mm Pitch Pico-Lock 504051 Series Crimp Housing material is UL94V-0 rated. The design of the Molex 1.50 mm Pitch Pico-Lock 504051 Series Crimp Housing includes polarisation ribs and slots to provide fool-proof mating.
Note
Molex Connector Housing, High-Temperature Thermoplastic Material, -25°C to +85°C Operating Temperature Range - 504051 Series - 504051-0401
To achieve a robust PCB assembly, slot your crimped terminals into this connector housing from Molex. It's designed for use with an SMT wire-to-board header and completely encloses sensitive electrical links to keep out contaminants. The integrated lock-to-mating feature maintains a solid grip on the connector so you can be sure of a stable hold, even in vibrating conditions.
Features & Benefits
• Safe to use in challenging conditions, thanks to an operating temperature range of -25°C to +85°C
• Polarized-to-mating design cuts out the risk of damage caused by misalignment
• Single-row layout with 4 contacts offers a simple and neat way to manage multiple circuits

What size is this housing?
It has compact external dimensions of 9.95 (L) x 1.92 (W) x 6.4mm (D), so it's a space-saving option for miniature assemblies.
1.5mm Wire to Board - Molex Pico-Lock
The Molex 1.50 mm Pitch SMT Pico-Lock Wire-to-Board system provides positive locking with high current capacity and a very low profile on the PCB. The unique side positive lock design of the Molex 1.50 mm Pitch SMT Pico-Lock Wire-to-Board system give this connector its ultra low profile with a mated height of 2 mm. Additional mating assurance of the Molex 1.50 mm Pitch SMT Pico-Lock Wire-to-Board system is provided via top friction locks, visual mating confirmation and by the header having a wide solder tab that is shaped to pass over the top of the housing providing additional mechanical stability. Operator handling is aided by the Molex 1.50 mm Pitch SMT Pico-Lock Wire-to-Board systems mating guide rib design which also provides polarization. The materials used for the Molex 1.50 mm Pitch Pico-Lock Wire-to-Board system are RoHS and Low-Halogen compliant.
