M20-7831042 Description

Short technical summary and product information.

The M20-7831042 is a 20-position receptacle connector from Harwin Inc.'s M20 series. It features a 2.54mm (0.100") pitch and through-hole solder termination, making it suitable for board-to-board or cable interconnections. The connector has a push-pull fastening mechanism and is housed in a black UL94 V-0 rated thermoplastic insulator.

 

Electrical ratings include a current rating of 3A per contact and a voltage rating of 1000V. Contact resistance is 20mΩ maximum initially, and 30mΩ after conditioning. The dielectric withstanding voltage is 1000V AC for 1 minute, with insulation resistance of 1000MΩ minimum. The operating temperature range is -40°C to 105°C.

 

Mechanically, the connector has 20 positions loaded in 2 rows with a row spacing of 0.100" (2.54mm). Mated stacking heights available are 11.04mm and 12.63mm. The contact finish is Tin (flash), and the contact material is copper alloy (per datasheet). Insulation height is 8.51mm (0.335").

 

The connector is designed for through-hole mounting, typically used in PCB applications requiring reliable low-current interconnections.
