Broad line of compact limit switches from heavy-duty foundry types to light-duty snap switches.
Rugged designs are vibration and shock resistant, and environmentally sealed for indoor, outdoor, and washdown service. These switches are available with a wide variety of lever and plunger actuators. Many models include an integral LED lamp to indicate the operating status of the switch.

===================================================================================== QL (AZ4) Series
Key features
- Same compact size as the VL mini limit switch A compact limit switch perfectly suited to this era of space-saving.
- Sturdy construction A sturdy construction comparable to any limit switch which uses a zinc die-cast body, a glass-weave Reinforced plastic head, and a cover. The terminal cover also boasts excellent dust-proof and drip-proof capabilities.
- Easy wiring Because this unit uses the same terminal screw wiring method as the VL mini limit switch, the wiring space is large and the wiring work easy.
- Highly accurate position detection Because hardly any pretravel (P.T.) is necessary, highly accurate position detection is possible.
- Detection of thin sheet materials is also possible Because the movement differential (M.D.) is zero, detection of thin sheet materials is also possible.
- Level control of conducting fluids is also possible Because contact detection is possible, the level of conducting fluids can also be controlled.
- High frequency detection possible Because the output is contactless, there is no chattering or bounce at all. This makes for fast response speed and high frequency detection, with long unit life.
- Comes with operation display lamp Any operation can be verified by means of the blinking light-emitting diode.
- Comes with sensitivity adjustment function The sensitivity can be set appropriate to the application by adjusting the touch sensitivity.
=====================================================================================
ML (AZ7) Series
Key features
- Long life High efficiency coil spring switching mechanism for long life: More than 107 mechanical operations.
- Great mechanical strength while being compact and lightweight The attachment pitch is 25.4mm (1.000inch), same as for the Z basic model microswitch. Also, the outer cover cap uses a strong plastic with excellent mechanical characteristics. An M4 bolt can be used for the attachment.
- The overtravel (O.T.) is large with great shock absorption
- The switch itself is constructed to be dust-proof and oil resistant The switch itself is closed flush with the diaphragm and the compressed rubber ring, so that the terminal mold type (epoxy-sealed terminal type) is perfectly flush with the terminal parts.
Typical applications
Used in sequence control of food processing machines, automatic packaging machines, conveyers, and processors. Ideal for light industry machinery when installation pace is limited and a protective construction is sought.
=====================================================================================
SL (AZ3) Series
Key features
- Subminiature limit switch Managed to miniaturize the comparative bulk with high density mountings in the equipment’s detector to approximately 1/3 of our own ML limit switches, or approximately 1/1.6 of the Z model microswitch.
- A lamp can be easily added for operations checks An exposed terminal type model combined with a socket with cord for the built-in LED lamp (sold separately) easily become a limit switch with lamp. Convenient for maintenance checks such as operations checks.
- Operates with a light force Comes in two types: O.F. is a maximum of 1.18N {120gf} (light force model) and light force commensurate to the microswitch.
- Terminal uses both solder and tab
- Achieves stroke tolerance (O.T./T.T.) of 0.67 Plenty of scope for position fixing with long life. Because of the optimum design of the built-in limit switch and the original Lmodel spring for use in O.T. absorption, the total travel range has been enlarged, and both position fixing and the unit’s lifespan have been improved a level. Stroke range: 3 times more than the ML limit
- Long life By combining the excellent reliability and solvent proofing of the FS-T microswitch with the L shape spring, we have achieved a unit with both long life and high reliability (electrical life: 105 mechanical life: 10^7
- Built-in safety features and excellent environment proofing The case uses 66 nylon glass fiber the doubly protect the switch. Also, the body and cap have been ultrasonically welded, creating a flush construction except for the terminals. Moreover, by adding a dedicated socket, the construction is drip-proof, dust-proof, and dirt-proof, creating a flush construction for the unit as a whole including the terminals. Rubber cover type: Equivalent to IP60 Socket with cord type: Equivalent to IP64
===================================================================================== VL (AZ8)Series
Key features
- Compact design approximately 1/3 of the AZ5 limit switches
- Au-clad contacts that can even use low level circuit and little chattering and bouncing The built-in switch has Au-clad contacts with excellent contact reliability and uses a crossbar contact method, and moreover, has a dual cutoff circuit (1 Form A 1 Form B contact) with little chattering and bouncing due to computer-operated analysis.
- Easy wiring with full-open terminals When the cover is removed, the terminals are open as far as the flank, so the necessity to insert your fingers into a case to complete the wiring has been removed. Moreover, the wiring space is large despite the compact size, and the terminals are spread in a tiered array, so that wiring work can be completed very easily. The cable can either be screwed in directly, or can use U-shaped and circular pressure terminals.
- Mounting are possible to both front and back
- Type with a lamp that can be used with a wide range of voltages • With neon lamp Compatible with: 100 and 200V AC ; Even at 100V AC, sufficient luminosity is achieved through the diamond-cut lens. Also with a long lifespan of more than 20 thousand hours. • With LED lamp Covers 6 to 48V DC and comes in three types, 6V DC , 12V DC , 24 to 48V DC. Uses two highly luminescent LEDs and in addition, sufficient luminosity is achieved through the diamond-cut lens.
- Lamp connection can be either spring type or lead wire type • Spring type (wiring unnecessary) (With neon or LED lamp type) Wiring is unnecessary because the lamp is directly connected to the terminals. By simply changing the direction of the lamp holder attachment, it is possible to display both lights during inoperability and during operation (however, if both N.O. and N.C. loads are connected, only the inoperability lamp can be displayed.)
- Construction permits lamp attachment method to be changed. • Lead wiring type (LED lamp type only) Because the wiring can be made parallel to the load, current leakage from the lamp can be reduced to 0. Even with a slight leak, the electronic circuit incurring the leak can be used safely.
- Dust-proof, waterproof, oil resistant construction The main unit and the cover are sealed with rubber packing, and the cord runner is doubly sealed by the cord vent. The actuator is sealed by both a rubber cap and an O ring in all models. Also, the lens and cover are formed simultaneously with the lamp type, and moreover, a nameplate is affixed to the upper surface, thereby improving the already excellent waterproof capabilities. (Note: Applications directly involving the cord entrance and the locations which are always wet and oily, or submersion in water or oil, cannot be used.)
Typical applications
Ideal for general plant facilities such as engineering machinery, conveyer machinery, and assembly lines LED lamp type is also compatible with low-voltage DC control circuits such as in PCs and computers.
