Connectors with stainless-steel housings must be used where they are exposed to aggressive substances. Positionable panel mount connectors for the alignment of the guide tab using a positionable nut are available in die-cast zinc housings. The new, positionable versions in stainless steel from Binder are also potted in the single wires section. This prevents contaminants from intruding into the customer housing. The standard length of the single wires is 200 mm. The supplier recommends using protection caps from its range of accessories for additional protection of the contact area when they are unmated.
