Safety Components are required for safety countermeasures in equipment and facilities. They are used for shut-out detection of mechanical guards, checking intrusion into hazardous areas, and building safety circuits.

  • Safety Sensors
  • Safety Door Switches
  • Safety Limit Switch
  • Emergency Stop Switches
  • Safety Switches
  • Safety Relays

Relays are devices making or breaking electric circuits by their output section driven by operational signal, which is triggered by electric input signal controlled by switching devices.

  • General purpose relay
  • I/O Relay terminal
  • Terminal Relays
  • Power Controllers

Control Components provide ideal control at production site through Counters, Cam Positioners. Timers, Timer Switches. Digital Temperature Controllers, and other input, control, and output components.

  • Temperature Controllers 
  • Timers 
  • Counters 
  • Cam Positioners 
  • Digital Panel Indicators Signal Converters 
  • Programmable Relays 


Servo motors and inverters ideal for positioning, speed and torque controls in various business machine control fields

  • Machine Automation Controllers
  • Inverters
  • Servo Motors/Servo Drivers.

Sensors & Switches

A sensor is a device that detects and responds to some type of input from the physical environment. The specific input could be light, heat, motion, moisture, pressure, or any one of a great number of other environmental phenomena. The output is generally a signal that is converted to human-readable display at the sensor location or transmitted electronically over a network for reading or further processing.

  • Fiber Sensors  
  • Photoelectric sensors  
  • Displacement Sensors 
  • Vision Sensors
  • Code Readers 
  • Proximity Sensors
  • Photomicro Sensors  
  • Rotary Encoders 
  • Ultra-Sonic Sensors 
  • Pressure Sensors 
  • Contact Sensors
