Touch Swiches Product line
Ultra-compact High Precision PT-Touch Switches
World’s smallest level M5 x 17mm
enables miniaturization of machines
The world’s smallest size with a repeatability of 1μm, enabling precision positioning in a tight space and miniaturization of machines.
High Precision MT-Touch Switches
0.5 μm repeatability without amplifier
IP67, highly resistant to adverse environments
Top-of-the-line switch model for accuracy and durability
Performs precision positioning in adverse environments with splashing water, oil, coolant, and chips.
CS-Touch Switches
Compact and low-cost
No mutual interference even when spaced at 5 mm intervals
Extensive variations and optional contacts. The best-selling positioning switches.
Ball Plunger Switch Sensors
World’s smallest: φ4
Ball plunger with built-in switch
Indexing by ball plunger and confirmation signal output. Reduce the number of parts to make smaller machines at lower costs.
Stopper Bolt Switches Sensors
Two-in-one unit
Stopper bolt with built-in switch
Stops the workpiece with a stopper bolt and outputs a confirmation signal. Reduce costs by reducing the number of parts!
Micro-stopper Switches
Compact size (8 x 8 mm dia.)
Mountable on robotic fingertips
It can be directly embedded in a limited mounting space for chuck confirmation of a robot hand, workpiece seating confirmation, among others, to reduce the size of the machine.
Spring Plunger Switch Sensors
Two-in-one unit
Spring plunger with built-in switch
Workpiece ejection by spring plunger and confirmation signal output.
Reduce the number of parts to make smaller machines at lower costs!
Low-contact Force Switches
Low contact force of 0.1N
Ideal for detecting workpieces prone to scratching or deformation, such as semiconductors and ceramics.
Heat-resistant HT Switches
Usable in high temperature environments up to 200°C
Touch switches made of heat-resistant materials. The HT series is the only switch usable in high temperature environments such as in tooling and injection molding machines.
Switches for High Vacuum Class
High vacuum at 10-5Pa with low outgassing
Switches made of low outgas materials. Lower cost than sensors with amplifiers. Used in many wafer and mask detection applications in vacuum chambers and semiconductor manufacturing equipment.
