RS232

Like any integrated circuit the controller will need some peripheral components to make it run properly

Keep the XTAL as close as possible to the IC. Where applicable connect the XTAL housing to GND. A via fence reduces coupling to the GND plane. An oscillator can be used alternatively.

Load capacitors should be low leakage and stable across temperature range (NP0). For the capacitive load (cload) the stray capacitance of the PCB and the IC pins should be considered:

C_L = (C₁*C₂) / (C₁+C₂) + C_stray

C_stray ≈ 3…6pF

Digital Isolators provide a galvanic isolation of signals and reliable data transmission in high-speed applications with rates up to 150 Mbps. The WPME-CDIx series optionally includes an isolated power supply and provides an isolation voltage of up to 5000VRMS. All part numbers are UL1577 recognized and have VDE 0884-17 and IEC 60747-17 certificates.

The use of isolated signal lines often facilitates the need for an isolated power supply for sensors or other peripherals. Integrated power modules simplify the design and accelerate the development

D-SUB Connector

We can provide the well established D-Sub connector. Not only do we have the male and female version in our portfolio, but with the angled and non angled versions and fitting cable options we can fully support you and your needs.

Terminal Blocks

To further support the needs of our industrial customers we also have a wide range of Terminal Blocks. From a technical aspect we support THT, THR and SMT and we have different pitches, ranging from 2,5mm up to 7,62mm, when looking at our pluggable portfolio. To give you an overview of the fixation types we can offer: Wire Protector, Rising Cage Clamp, Excenter Clamp, Screwless Spring Clamp, Screwless Push In, Pluggable and IDC Clamp.
