SMT ZIF connector has a folding lock to keep a low profile

Zero insertion force (ZIF) connectors are able to be used where connecting without tools and high retaining forces are required in limited spaces, says W+P. The company offers zero force connectors with its 5566 and 5577 series. They have a low pitch of 0.5 and 1.0mm and low design height of 1.2 and 2.0mm. 

These connectors also feature a locking option at the rear. A special folding mechanism, which is similar to a piano cover, simplifies handling and saves space on the PCB, compared with a front locking mechanism.  This ensures a stable and durable connection, which is still able to be released, says W+P.

To complement the 5566 and 5577 connectors, W+P offers a corresponding flexible cable in its 599 series. These are available with pitches of 0.5 to 2.54mm, and variable cable lengths, connection types, types, and customer-specific designs. They are also suitable for contacting flexible PCBs.

Surface mount ZIF connectors have double-sided horizontal contacts, which increases their flexibility when used on PCBs. They are available featuring four to 40 or six to 60 contacts, and are designed for currents up to 0.5A per contact.

The contact material consists of a gold plated copper alloy with nickel barrier layer. Halogen-free, high-temperature resistant plastic is deliverable as an insulating material according to UL94 V-0. The operating temperature ranges from -40 to +85 degree C for the series 5566 and from -25 to +85 degree C for the series 5577. Both connectors are distributed in tape & reel packages suitable for automated assembly.

The compact form factor makes the 5566 and 5577 suitable for use in confined spaces, such as industrial computers, audio and telecommunications devices, data drives, scanners, printers and LCD displays.
