BASE rotary limit switch, ratio 1 : 20, 2 switches, IP67

Features BASE rotary limit switches

- Consists of gear motor that transfers movement through primary input reduction stage (worm gear and helical toothed gear) and one or more secondary output stages (pairs of straight toothed gears).
- Cams can be accurately adjusted by means of screws.
- Positive opening NC contacts for safety functions.
- Mechanical life of switches: 1 million operations.
- IP protection degree: every Base is classified IP42, IP65 or IP66, IP67 and IP69K.
- NEMA protection degree: Base models with IP66, IP67 and IP69K are classified Type 3. Base switches with IP42 are classified Type 1.
- Extreme temperature resistance: -40℃ to +80℃ (operating + storage)
- Stainless steel transmission and gear driving shafts, self-lubricating techno-polymer gears and driving bushes, techno-polymer base and cover.
- Sintered bronze bushes are molded into the base of the limit switch to optimize shaft rotation and prevent rubbing with plastic material.
- All materials and components used are wear resistant and guarantee protection of the unit against water and dust.
- Insulation category: Class II
- Maximum rotation speed: 800 rev./min.
- Cable entry: Cable clamp M16
- Precursor BASE: TER MF2C
