Contact has introduced a PCB terminal block for Profinet-compliant data
transmission applications. There are four
variants of the PCB terminal block — MKDS 1, SPTAF 1, ZFKDS 1,5C and SPT
2,5 — and each one of them has been designed specifically for the connection of
twisted-pair conductors with cross-sections of 0.14 mm² to 4 mm².


conductor connection is made either via spring-cage connection or ZFKDS 1,5C;
screw connection or MKDS 1; or push-in spring connection — SPTAF 1 and SPT 2,5.
All variants satisfy the requirements of the Profinet directive, version 4.00,
and thus are suitable for secure data transmission as per Cat5 cabling

angled variant, ZFKDS 1,5C series, as well as horizontal and vertical PCB
terminal blocks, the SPT 2,5 series, are also approved for use in
explosion-proof areas according to the IEC 60079-7 specification.

These Profinet-compliant PCB terminal blocks
extend the range of the existing field and device connectors like M12 and RJ45,
so they can provide efficient connection solutions for devices in industrial
