Miniature Safety Limit Switch
Safety Limit Switches compatible Popular D4D, Providing Full Lineup Conforming International Standards
Lineup includes three contact models with 2NC/1NO addition 1NC/1NO, contact models. Models with contacts available too. M12-connector models available, saving labor simplifying maintenance. Standardized gold-clad contacts provide high contact reliability. used with both standard loads microloads. Free lead, cadmium, hexavalent chrome, reducing burden environment. Conforms EN115 EN81-1. Lineup includes both slow-action snap-action models with contacts.

Structure, Names, Functions
Structure
Safety-oriented Lever Setting (Form-lock construction) Grooves which engage lever lever rotary shaft prevent lever from slipping against rotary shaft. There resin-lever metal-lever types.
Head direction switch head varied four directions. (Roller plunger models mounted either directions angle.)
Conduit Opening
wide variety conduits available.
Built-in Switch built-in switch direct opening mechanism that forcibly separates contact even when there contact deposit.
Cover cover, with hinge lower part, opened removing screw cover, which ensures ease maintenance wiring.

Safety Precautions
Refer OMRON SAFETY COMPONENTS SERIES (Y106) common precautions Switches Safety Limit Switches.
Mounting Method
Mounting Screw Tightening Torque
Tighten each screws specified torque. Loose screws result malfunction Switch within short time. Terminal screw Cover clamping screw Head clamping screw Lever clamping screw Body clamping screw Conduit mounting connection, adaptor screw (except 1/214NPT) (1/2-14NPT)
CAUTION
metal connectors metal conduits with this Switch. Doing occasionally result electric shock.
Precautions Safe
drop Switch. Doing result Switch performing full capacity. attempt disassemble modify Switch. Doing cause Switch malfunction. Switch where explosive gas, flammable gas, other hazardous present. Switch submerged water, locations continuously subject splashes water. Doing result water entering Switch interior. (The IP67 degree protection specification Switch refers water penetration while Switch submersed water specified period time.) Protect head from foreign material. Subjecting head foreign material result premature wear damage Switch. Although switch body protected from penetration dust water, head protected from penetration minute particles water. Turn power before wiring. Doing result electric shock. Install cover after wiring. doing result electric shock. Connect fuse Switch series protect Switch from short-circuit damage. fuse with breaking current times larger than rated current. conform ratings, IEC60269-compliant 10-A fuse type switch circuits more standard loads (250 VAC, same time. Doing adversely affect insulation performance. durability Switch greatly affected operating conditions. Evaluate Switch under actual working conditions before permanent installation within number switching operations that will adversely affect Switch's performance. sure indicate machine manufacturer's instruction manual that user must attempt repair maintain Switch must contact machine manufacturer repairs maintenance. Check Switches before inspect regularly, replacing them when necessary. Switch kept pressed extended period time, components deteriorate quickly, Switch release.
Switch Mounting
Mount Switch using screws washers tighten screws specified torque. safety, screws that cannot easily removed, equivalent measure ensure that Switch secure. Secure Switch with bolts washers. Provide studs with diameter 4-0.05/-0.15 height max. places, inserting into holes bottom Switch shown below that Switch firmly fixed four points.
Precautions Correct
Environment
Switch intended indoor only. Switch outdoors. Doing cause Switch malfunction. Switch where hazardous gases (e.g., H2S, SO2, NH3, HNO3, CI2) present locations subject high temperature humidity. Doing result damage Switch caused contact failure corrosion. Switch under following conditions. Locations subject extreme temperature changes. Locations where high humidity condensation occur. Locations subject excessive vibration. Locations where metal dust, processing waste, oil, chemicals penetrate through protective door. Locations subject detergents, thinner, other solvents.
