Connectors for exposed environments.

The Weald Electronics LMF and LMG families of connectors and accessories are now available through Lane Electronics. Both connector families are suitable for cable to panel or cable to cable connections and are designed for use in exposed, harsh environments. such as mining and construction, and offshore installations including wind farms and oil and gas platforms. 

LMF and LMG Connectors are available with 1 to 37 contacts and housed in a range of shell styles and sizes:

• Shell Size 1 – Small
• Shell Size 2 – Medium
• Shell Size 3 – Large

Two shell materials are available, aluminium with fine thread coupling, suitable for lightweight use and brass, with coarse thread coupling, suitable for more rugged applications. Both types are IP67 rated and maintain high levels of mechanical strength and corrosion protection, while the selection of brass eliminates the need for protective plating that can get scratched and requires no in-service maintenance.

The comprehensive range of accessories includes straight and angled outlets for screened and unscreened cables and conduits, metal and polymer protective caps, and assembly tooling.

The LMF Range, formerly known as Plessey MK4, has an operating temperature range from -40 °C to +85 °C, with a limited environmental capability. The standard range of shell styles includes climatic proof bulkhead feedthrough connectors which permit a complete break in a cable passing through a bulkhead. Furthermore, thermocouple connectors can be configured with an additional choice of alumel and chromel / brass and constanton contacts.

The LMG Range, formerly known as Plessey MK7 (Patt. 104), is an update on the LMF range and has a more comprehensive environmental performance. Standard inserts are polychloroprene and the operating temperature range is -55 °C to +100 °C. For more demanding applications fluorinated silicone rubber may be selected for insulators and the temperature range increases to -55 °C to +150 °C.

Should the occasion demand, the LMF and LMG connectors are intermateable within their respective styles and types, with performance limited to the LMF capability. The LMG range does not include bulkhead feedthrough connectors style or thermocouple contact options.
