S-T50 AC220V Limit sensor

S-T50 AC220V Limit sensor
Common Applications

• Motor Control: Starting, stopping, and preventing motor burnouts on industrial conveyors and machinery.
• Safety Limits: Acting as the main switching relay tied to your limit sensors (like roller-plunger switches) to kill the motor circuit when a physical boundary is reached. 

 Specifications

• Coil Voltage: \(200\text{V} - 240\text{V AC}\)
• Capacity: 22 kW (at \(380\text{V} - 440\text{V}\)) / 15 kW (at \(220\text{V} - 240\text{V}\))
• Auxiliary Contacts: Built-in 2NO (Normally Open) + 2NC (Normally Closed)
• Product Standard: Global IEC and JIS compliance 

 Wiring Your Limit SensorTypically, a 220V AC limit switch acts as an NC (Normally Closed) safety stop. When tripped by the physical mechanism, the limit switch opens the circuit, breaking the power to the S-T50’s A1/A2 coil terminals. This drops the magnetic contactor, halting the motor
