ept Zero8 SMT board-to-board connectors

Looking for a PCB connector that is robust, shielded, and guarantees reliable contact? One that can ideally be scaled to your individual requirements as well? ept offer a new series of robust board-to-board surface mount connectors with a 0.8 mm pitch.

Zero8 connectors are equipped with a new type of contact system, ScaleX that meets the highest safety requirements of industrial PCB connections and are available with 12, 20, 32, 52, or 80 contacts



Looking for a PCB connector that is robust, shielded, and guarantees reliable contact? One that can ideally be scaled to your individual requirements as well? ept (Zero8) and Phoenix Contact (FINEPITCH 0.8) have launched a new series of robust board-to-board connectors with 0.8 mm pitch.
ept’s Zero8 product range was developed especially for demanding industrial applications while simultaneously offering ultimate scaleability: this lets you customise the construction types, stack height, and number of contacts to meet your individual needs. The socket and plug are currently available in the mid-profile and low-profile versions. with angled versions arriving in the future. Thanks to their various structural heights, the Zero8 PCB connectors let you implement board-to-board distances of 6.00 to 20.00 mm. We can provide a variable number of contacts between 12 and 80.
The robust, double-sided ScaleX connection technology stands up to the difficult conditions found in industrial applications and guarantees secure contacting under exposure to mechanical stresses such as shock and vibration. In addition, Zero8 connectors compensate for tolerances on the device side in all directions when connected. Thanks to their EMC shielding, your signals are perfectly protected against external influences in the industrial environment, and the material composition guarantees a data transmission rate of up to 16 Gbit/s. The double-sided shield concept guarantees trouble-free data transfer in industrial environments: the shielding material used is especially suitable for components with high requirements in terms of electromagnetic compatibility and guarantees a coupling inductance of max. 10 pH for the connector. The extensive shield concept reliably dissipates interfering currents by means of multiple contacting on both PCBs in the direction of the ground connection. This protects the connector against electromagnetic interference (load), but also adjacent components if the connector acts as a source of interference.
We have also thought one step ahead: the plug geometry is designed so the contacts cannot be damaged even in the event of faulty operation.
