Emergency Stop Switch A22E Install in 22-dia. or 25-dia. Panel Cutout • Direct opening mechanism to open the circuit when the contact welds → . • Safety lock mechanism prevents operating errors. • Easy mounting and removal of Switch Blocks using a lever. • Mount three Switch Units in series to improve wiring efficiency (with non-lighted Switch Units, three Units can be mounted for multiple contacts). • Finger protection mechanism on Switch Unit provided as a standard feature. • Install using either round, or forked crimp terminals. • Oil-resistant to IP65 (non-lighted models)/IP65 (lighted models) Note: Be sure to read the precautions for all pushbutton switches in the Pushbutton Switches Group Catalog (Cat. No. X018), as well as the “Safety Precautions” on page 19. Features Safety Lock Mechanism to Prevent Misuse Construction Operation Unit Color: Red Non-lighted Lighted Lock position Lamp This Switch enables emergency stops only when the pushbutton is pressed intentionally and firmly. Even if an object or person touches the pushbutton by mistake, the contact will not be released unless the pushbutton reaches the lock position. This Switch uses a finger protection mechanism to prevent electrical shocks. Moreover, it is provided with a mechanism to prevent terminal screws from coming off and also allows connection to either round or forked crimp terminals.

No. X018). Using the Microload Do not apply a voltage exceeding the rated voltage across the incandescent lamp terminals. The lamp may be destroyed and the operation unit may fly out. ■ Precautions for Correct Use Mounting • Always make sure that the power is turned OFF before wiring the Switch. Also, do not touch the terminals or other current-carrying ports while power is being supplied. Electric shock may occur. • Do not tighten the mounting ring more than necessary using tools such as pointed-nose pliers. Doing so will damage the mounting ring. The tightening torque is 0.98 to 1.96 N·m. • Recommended panel thickness: 1 to 5 mm. • Contact failure may occur if a Switch designed for a standard load is used to switch a microload. Use Switches within the application ranges shown in the following graph. Even within the application range, insert a contact protection circuit, if necessary, to prevent the reduction of life expectancy due to extreme wear on the contacts caused by loads where inrush current occurs when the contact is opened and closed. The minimum applicable load is the N-level reference value. This value indicates the malfunction reference level for the reliability level of 60% (O 60) (conforming to JIS C5003). The equation, O 60 = 0.5 x 106/time indicates that the estimated malfunction rate is less than 1/2,000,000 with a reliability level of 60%. Voltage (V) !CAUTION Wiring 0.16 mA 100 mA 1.6 mA 30 24 • When DC-specific LEDs are used, wire the Switch so that the X1 terminal is positive. • Terminal screws must be Phillips or slotted M3.5 screws with a square washer. • The tightening torque is 1.08 to 1.27 N·m. • Single wires, stranded wires, and crimp terminals can be connected to the Switch. • Applicable Wiring Materials: Twisted strands: 2 mm2 max. Solid wire: 1.6 mm dia. 8 mm dia. max. 8 mm max. Naked Crimp Terminals 16.0 mm max. Crimp Terminals with Insulating Sheaths 16.0 mm max. 8 mm max. 20.2 mm max. 8 mm dia. max. Microload area Area of use Standard load area 12 Invalid area 5 0 0.1 1 mA 10 mA 1 10 100 1,000 Current (mA) Others • If the panel is to be coated, make sure that the panel meets the specified dimensions after coating. • Due to the structure of the Switch, severe shock or vibration may cause malfunctions or damage to the Switch. Also, most Switches are made from resin and will be damaged if they come into contact with sharp objects. Particularly scratches on the Operation Unit may create visual and operational obtrusions. Handle the Switches with care, and do not throw or drop them. 20.2 mm max. • After wiring the Switch, maintain an appropriate clearance and creepage distance. Do not allow the Switch to drop and hit the floor. Operating Environment • The IP65 model is designed with a protective structure so that it will not sustain damage if it is subjected to water from any direction to the front of the panel. LEDs • The LED current-limiting resistor is built-in, so internal resistance is not required. • If commercially available LEDs are used, select the ones that meet the following conditions: Base: BA9S/13@ Overall length: 26 mm max. Power consumption: 2.6 W max. Do not place or drop heavy objects on the Switch. Do not operate the Switch with hard or sharp objects. Hammer Screwdriver ALL DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527. Cat.
