Würth Elektronik extends its terminal block connector series Screwless alternatives and THR versions Waldenburg (Germany), November 28, 2023 – Würth Elektronik is extending its WR-TBL series by screwless push-in connectors in the 3.5mm and 3.81mm pitches. The new 4101, 8101, 4093, and 8093 series come close to matching the specifications of the screw-fixed connectors and can replace them. Another important feature for customers with SMT-dominated production lines: The THR series 8101 and 8093 are designed for soldering in the reflow oven. The housing of the connectors in the THR series is made of a high-temperature plastic, the pins are shorter in length, and the connectors are supplied in automatically processable belt format. The 4101 (THT) and 8101 (THR) series in the 3.5mm pitch are available with horizontal, vertical, and 45° cable entries. The 4093 (THT) and 8093 (THR) series in the 3.81mm pitch have a 45° cable entry. The terminal blocks are available from stock with two to twelve pins. 13- to 24-pin connectors can be supplied on request as per customer specifications. All the series named above have both cULus and VDE certification.
