E50TD1 is a two-step convertible heavy-duty plug-in limit switch designed for CW (clockwise), CCW (counterclockwise), or both directions of operation. It features a travel to operate contacts of 10° for each step (1st and 2nd), with a 4° travel to reset contacts and 90° total travel. The switch requires 3 in-lbs force to operate contacts and provides a minimum return force of 4.5 in-oz. Constructed with a zinc die cast enclosure and standard Viton gaskets, seals, and boots, it offers exceptional chemical resistance to common coolants, cleansing agents, and hydraulic fluids. This limit switch is ideal for machine tool, automotive, waste water treatment, and other heavy-duty industrial applications requiring reliable position sensing.
