Signal Double Lock Connectors

Secondary locking for connection security

Compact signal double lock connectors offer secondary locking in wire-to-wire and wire-to-board configurations.

The 2.5 mm [.098”] centerline pitch signal double lock (2.5 SDL) connectors are compact, single row connectors available in both wire-to-wire and wire-to-board configurations. The signal double lock connector accepts 26-20 AWG [.121-.601 mm²] wire with insulation diameters up to .071” [1.8 mm], a voltage rating of 50VAC or VDC, and is rated up to 3A per line.  The signal double lock connector system consists of plug and cap housings for wire termination, optional double lock plates, crimp contacts and PC board pin headers in both standard and high profile versions. Double-lock plates ensure positive loading of contacts in the housing and prevent contacts from being mated halfway. PC board-mount post headers are available in two styles: standard profile and high profile.

Product Facts
  • Connector for signal circuits with one row of contacts on 2.5mm centerline
  • Wire-to-board and wire-to-wire connectors, consisting of plug and cap housings for wire termination and PC board-mount post header
  • Mounted to plug and cap housings for wire application, double-lock plate ensures positive loading of contacts in the housing. It also prevents contacts from being mated halfway
  • Double-lock plate is contained completely within the plug and cap housing, which provides neat overall appearance
  • Accepts AWG #26-20 wire with insulation diameters of up to 1.8mm
  • PC board-mount post header is available in two styles: standard profile and high profile 
  • High profile post header has locking feature at location fit to a resin coating applied to the board for waterproof protection for applications such as home appliances. The coating does not hamper mating and locking of post header with plug housing
  • Locking structure is inner-lock type and has clean surface 
  • Solder tail section of post header is provided with kinks to retain the header firmly on PC board during soldering
  • Radial tape-mounted version of post header is also available that is applicable to radial mounting machines  

Frequently Asked Questions

FAQs

Question Answer

What are the current and voltage requirements for your application?

 

The signal double lock connector system has a maximum current rating of 3 Amps per line and is rated for 50 Volts AC/DC.
What are the wire type and size requirements?

The signal double lock connector system is approved for use with 26-20 AWG wire with a wire insulation range between 0.93 mm and 1.8 mm.

 

What are the number of positions and available space?

The signal double lock connector system is available in 2-12 position wire-to-board and 2-10 position wire-to-wire configurations on a 2.5 mm pitch. The overall mated length of the free-hanging system is 22.6 mm and the maximum height with the standard profile header is 13.7 mm while the maximum height with the high-profile header is 19.2 mm.

 

What are the operating temperature requirements?

 

The signal double lock connector system has a maximum operating temperature of 105°C. For more information regarding operating temperatures refer to Product Specification 108-5459.

Is contact back-out a concern? Do you need confirmation that the contacts are seated?

 

The signal double lock connector system offers an optional double lock plate. The purpose of the double lock plate is to allow the contacts to be fully seated in the housing.

Do you need to differentiate this connector from other connectors in the application?

 

The signal double lock connector system offers multiple options of colored housings for ease of connector identification during manufacturing and assembly.

What is the benefit of choosing high-profile over standard-profile headers?

 

The signal double lock connector system offers high-profile headers for applications where there will be additional processing or resin coating of the PCB’s during the manufacturing process.
