FAQs
Installation is straightforward: mount the block alongside the AF-series contactor, connect the 1 NC auxiliary circuit to the control circuit via screw terminals, and ensure a wire strip length of 9 mm. Use conductor sizes 0.75–2.5 mm² with ferrules or 1–4 mm² rigid conductors. Tighten to 1 N·m for reliable signaling and IP20 protection against incidental contact.
The block provides one NC contact and an auxiliary circuit rated at 125 V, with a low power loss of 0.15 W per pole. It uses screw terminals and supports flexible wiring (0.75–2.5 mm²) or rigid conductors (1–4 mm²). These specs minimize heat, simplify wiring, and improve durability in continuous control operations.
Yes, the block is suitable for AF116, AF140, AF146, AF190, AF205, AF265, AF305, and AF370 series. This broad compatibility enables a single signaling accessory to cover multiple machines, reducing spare parts inventory and enabling consistent control panel design across lines and future expansions.
The product carries CE Declaration of Conformity and UKCA/CCC attestations, plus a UL certificate for contactor accessories. It is RoHS compliant and listed under WEEE B2B. These certifications support compliance in diverse regions and simplify regulatory documentation for panel builders and OEMs.
ROI benefits arise from reduced wiring time, fewer field faults due to clearer signaling, and lower maintenance costs thanks to robust screw-terminal connections and IP20 protection. The low auxiliary power loss also minimizes heat within enclosures, enabling denser, more reliable control panels and faster project commissioning.
