SMC offers a variety of auto switches for actuators and air grippers.  Reed and solid state switches are available in a general purpose type or with 2-color indication, which allows the optimum operating position to be determined by the color of the light.  Solid state switches are also available in 2-color indication with diagnostic output, water resistant 2-color indication, built-in OFF-delay timer (200 ms), magnetic field resistant, heat resistant and wide range detection configurations.  Various lead wire lengths are available.

Trimmer auto switches can detect various size work pieces by the difference of more than 0.5mm. The sensor enclosure is rated IP67 and the amplifier is IP40. Trimmer switches are available in direct or rail mounting styles. The sensor and amplifier can be connected without restriction through the use of an e-con connector.

SMC's hygienic auto switches were designed to work in areas where the cylinder surface is washed.  Rail mounting allows a freely adjustable mounting position, including intermediate positions.  These switches are designed with as many curves as possible and no recessed areas leaving extremely small amounts of residual cleaning solvent.  D-F6 auto switches have a stainless steel case and set screw. 

Actuator stroke position sensor is an analog output over the entire length of the stroke.  The D-MP is available in 4 measurement ranges.  Unit is IO-Link compatible.

The D-MH1 series outputs the analog voltage according to the actuator stroke position. The D-MH1 offers both analog auto switch and/or display sensor Monitor, which allows for remote detection position setting. Labor is reduced by eliminating the need to fine-tune the switch mounting position and easy adjustment even in narrow place and moving parts By selecting either the 3-setting mode or the 2-setting mode, various uses can be accommodated and productivity can be improved.

The D-MH2 is an IO-Link compatible 2-in-1 auto switch that outputs process data based on the actuator stroke position. The switch can discriminate between a maximum of 3 position points and position setting can be done away from the actuator to reduce labor and improve productivity. Applications include position monitoring, workpiece detection and error detection .

IN574 Wireless Auto Switch is the solution for seamless and reliable cylinder position detection without the constraints of traditional wired systems. IN574 utilizes Wireless Power Transfer (WPT) for power supply and wireless communication, creating a truly cable-free experience. 

Eliminate the hassle and risks associated with wires, including disconnections, space limitations, complex wiring work, and switch failures due to cable deterioration. Being battery-less, the IN574 also removes the need for ongoing battery replacements and associated maintenance.

• Completely Wireless: Achieves both power supply and communication wirelessly for a truly untethered system.
• Battery-Less Design: Powered by WPT, removing the need for batteries. Each WPT can power up to 15 wireless auto switches.
