Product Overview
The Omron Z-15GW2-B is the hinge roller lever variant in the Z-15-series general-purpose basic switch line. manufactured by Omron Corporation. Hengyixin Automation ships this switch from our Xiamen warehouse with a 30-day DOA return window and a datasheet PDF included in the box.
It carries an SPDT (Form C) snap-action contact rated 15 A at 125 / 250 / 480 VAC resistive on a 0.5 mm contact gap (the G code), 0.98 N operating force, and 7.10 mm pretravel / 4.00 mm overtravel. The white nylon roller at the end of the lever slides along a cam or fixed stop without scratching the mating part -- the right pick for a door interlock or a conveyor position detector where a steel lever would mark the part.
Pick Z-15GW22-B for a higher-force 1.71 N short hinge roller lever.
Key Features
- Free position 36.50 mm / operating position 30.20 +/- 0.80 mm
- Dielectric 1000 VAC between non-continuous terminals, 2000 / 2500 VAC to ground
- 0.5 A at 125 VDC, 0.25 A at 250 VDC (DC rating, non-inductive)
- Contact resistance < 15 mOhm initial, insulation > 100 MOhm at 500 VDC
- SKU: Z-15GW2-B
- Series: Z-15-series general-purpose basic switch
Best-Fit Applications
- Limit switch on a pneumatic cylinder where the roller rides the end-of-stroke cam
- Conveyor position detector for a slow-moving part where 0.98 N of operating force is enough
- Door interlock on a control panel or a machine guard where the nylon roller rides a fixed cam
Buying Checklist
- Pick Z-15GQ22-B instead for a panel-mount roller plunger on a sliding bracket.
- Pick Z-15GW22-B instead for a short hinge roller lever with 1.71 N operating force on a fast-moving cam.
- Pick Z-15GW2-B for a hinge roller lever on the standard 15 A / 0.5 mm contact gap Z-15 body with M3.5 screw terminals.

FAQ for Z-15GW2-B
What is the difference between Z-15GW2-B and Z-15GW22-B?
Both are Z-15-series 15 A SPDT basic switches with a hinge roller lever on M3.5 screw terminals. The Z-15GW2-B is the long hinge roller lever with 0.98 N operating force and 7.10 mm pretravel. The Z-15GW22-B is the short hinge roller lever with 1.71 N operating force and a shorter pretravel. Pick the GW2 for a light-force cam or a slow-moving door. Pick the GW22 for a higher-force machine where a short lever can ride a fast-moving cam without over-traveling past the 4.00 mm overtravel spec.
What is the G / H / E code in the Z-15 model?
The G / H / E / H2 letter in the Z-15G / Z-15H / Z-15E / Z-15H2 model code is the contact gap family. G is 0.5 mm / 15 A standard. H is 0.25 mm high-sensitivity. H2 is 0.20 mm extra-high sensitivity. E is 1.8 mm high-capacity. The G code is the most common pick for a 250 VAC / 15 A general-purpose load. Pick the H code for a microload or a low-force detector below 100 mA. Pick the E code for an inrush load where the larger contact gap handles a wider arc.
What is the difference between the screw terminal (-B) and the solder terminal?
The -B suffix on the Z-15Gxx-B is the M3.5 screw terminal variant. The bare Z-15Gxx (no -B) is the solder terminal variant. The screw terminal accepts a ring or fork lug on a 14-22 AWG wire and is the right pick for a control panel where the wire may need to be disconnected for service. The solder terminal accepts a 20 AWG wire soldered directly to the lug and is the right pick for an OEM machine where the wire is part of the harness and never disconnected.
Can the Z-15GW2-B switch a 250 VAC solenoid or contactor coil?
Yes, at 15 A. The 15 A rating is the non-inductive resistive figure; for a 250 VAC contactor coil (inductive) derate to 1/3 to 1/4 of the rated current, so the practical limit on a 250 VAC coil is 5 A. The Z-15 is rated 1/4 HP at 250 VAC for a motor load, which is about 1.5 A. For a higher-current motor or a heater, use a G2R-2-SND interposing relay (5 A) or a G3NA-210B-UTU solid state relay (10 A) between the Z-15 and the load. For a 24 VDC solenoid, the Z-15's 0.5 A rating is plenty for a 1.5 W solenoid coil.
