Feature → Business Impact → Application: The block provides 1 NC auxiliary contact and 1 N.C. Ring Tongue terminal interface, delivering a clear, redundant signaling path with minimal contact resistance. This translates to improved interlocking accuracy and reduced risk of misoperation in control schemes; ideal for machine signaling, status indication, and interlock logic in compact panels. Application: fits AF-series contactors (AF116B through AF370B), enabling seamless integration into existing control architectures. Feature → Business Impact → Application: Low power loss of 0.15 W per pole supports energy-efficient control circuits, lowering overall panel heat and long-term energy costs. Application: suitable for continuous operation in standard industrial environments demanding reliable signaling with minimal thermal load.

FAQs
Install on compatible AF contactors (AF116B, AF140B, AF146B, AF190B, AF205B, AF265B, AF305B, AF370B). Use the ring-tongue terminals for the auxiliary circuit, strip wires to 9 mm, and tighten to 1 N·m. Ensure IP20 rating by mounting in a dry indoor panel and verify clearance around the device to prevent contact with live parts.
The block provides 1 normally closed contact, 125 V auxiliary circuit rating, and a per-pole power loss of 0.15 W. Wiring is flexible with ferrule 0.75–2.5 mm² or rigid 1–4 mm² connections, supporting reliable signaling with standard control voltages.
Yes. It’s designed to extend signaling and interlocking within AF-series control circuits, offering compact dimensions (14.9 mm width, 79 mm depth, 67.3 mm height) and IP20 protection for dependable operation in controlled environments.
The part supports CE and UKCA declarations, UL cURus certification for contactor accessories, and RoHS compliance. It also aligns with CMRT and WEEE guidelines, confirming responsible material use and end-of-life handling.
Maintenance is minimal due to solid mechanical contact and durable ring-tongue terminals. The low power loss reduces panel heat and energy costs, while compatibility with AF-series devices lowers installation time and wiring errors, delivering faster ROI through improved reliability and easier field servicing.
