CMZ series PCB low insertion force connectors
1、0 Insertion Force
The unlocking of the product is a single movement and it is the most innovative way the mechanism works without the two parts making contact. As the knob is turned, the module is propelled to move until the contacts engage, thus achieving zero-insertion-force docking.
2、10,000 Mating Cycles
The pin holes are non-contact mating so they have no friction. After fixation, the pin holes touch each other, and the contact parts are partially gold-plated with 20μ, thus allowing longer mating life and stable connection 3performance.
3、156 PIN High Density
The area of 25.1*108.2mm can provide up to 156 signal channels. Being square and small in size, it can be inserted side-by-side thus saving more space and being in line with the device miniaturization trend.
4、70% Cost Reduction
The company owns a factory and a fully integrated system covering design, R&D, production, procurement, and sales. It realizes cost reduction through various means such as process optimization, cost control, and channel expansion.

FAQ
Q1: Are pins included if the PCB board connector is purchased?
A1: The connector is equipped with square pins. One side is inserted into the connector, and the other side is soldered to the PCB board.
Q2: Is it possible for the PCB board connectors to be interlocked with those of non-PCB boards?
A2: Yes, the majority of customers decide to use the wired version for the handheld end (ITA side) and the PCB version for the non-handheld end (ICA side). Thus, it helps in saving the device space, reducing the wiring, and also considering the handing plugging ease.
