7551 and 7552 position limit switches are designed for the control of complex operating machinery. As they are control auxiliaries, they act on a power interface. The choice of materials, technical solutions and ample size make these limit switches ideal for use in strongly aggressive environments where they are exposed to the most severe operating conditions, guaranteeing impeccable function at all times and for their entire life.
7551 and 7552 limit switches are equipped with 4 fastening holes and 3 outputs for cable clamps to reduce installation time and facilitate wiring operations.
The enclosure is made of die-cast aluminum alloy and is resistant to any violent impact, chemical aggression and rust, while the bushings in sinterized material eliminate the need for any operations of routine maintenance of the head, since they are also made of impact-resistant zama.
