Sensor/actuator connector Plug. M8, pen, straight. Nowadays, individual cable lengths are often required. To meet this demand, Weidmüller offers a broad portfolio of connectors for free assembly. Plugs and sockets for free assembly for M8, M12, M16 and 7/8" connections are very robust and ideally suited, for example, for mechanical engineering. The M8 circular connectors are particularly suitable for applications with limited space. The insulation displacement terminal connection is characterised by fast and simple assembly, since with this technology the conductor is inserted directly into the plug without stripping or crimping. In addition, it has a high level of functional reliability.
