  • * Operation indicator attachment type classification
  • M900 series limit switch is generally composed of the product with operation indicator and without operation indicator.
    Also divided into the a.c type and d.c type operation indicator.
  • It can be used as an operation indicator just by changing the cover of limit switch.
    It does not need the separate connection and it selects ON/OFF by rotating the holder 180 degree.
Voltage a.c operation indicator (250 V a.c) d.c operation indicator (24 V d.c)
Model HY-LM90A (a.c) HY-LM90D (d.c)
Indicator type Neon lamp L.E.D
Leakage current approx 1.2 mA (250 V a.c) approx 1.0 mA (24 V d.c)
