Product Overview
The Omron Z-15GW22-B is a Z-series general-purpose basic switch with a short hinge roller lever and screw terminals It is manufactured by Omron Corporation. Hengyixin Automation ships this limit switch from our Xiamen warehouse with a 30-day DOA return window and a datasheet PDF included in the box. The SPDT snap-action contact is rated 15 A at 250 VAC resistive, 10 A at 500 VAC, 0.5 A at 125 VDC and 0.25 A at 250 VDC. The W22 suffix marks the short hinge roller lever with operating position 30.2 plus or minus 0.4 mm from the mounting hole centre. Mechanical life is 10 million and electrical life is 500,000 operations. Key specs: Contact Form SPDT (Form C) snap-action, silver alloy; Rated Load 15 A at 250 VAC resistive; 10 A at 500 VAC; 0.5 A at 125 VDC; 0.25 A at 250 VDC; Actuator Short hinge roller lever (W22), stainless-steel roller; Operating Force 160 gf (1.57 N) max; release force 42 gf min; Travel Differential 0.5 mm max; overtravel 2.4 mm min; OP 30.2 plus or minus 0.4 mm; Terminals Three M4 screw terminals (COM / NO / NC) with toothed washer;.

Best-Fit Applications
- Door-interlock switch on a small enclosure or machine guard where the roller rides the door frame
- Conveyor divertor position feedback where the roller rides the flag on the transfer arm on a 1,200 ppm line
- Spare replacement after 10 million operations on a legacy packaging machine where the panel cutout is 25.4 mm
Buying Checklist
- Choose the Z-15GW22-B when the panel needs a 15 A SPDT basic switch with a short hinge roller lever and screw terminals.
- Choose the Z-15GW2-B instead when a longer-reach standard hinge roller lever is needed on the same 25.4 mm mounting.
- Choose the D4N-112G instead when the switch needs IP67 sealing and conduit entry for outdoor or washdown use.

FAQ for Z-15GW22-B
What is the difference between Z-15GW22-B and Z-15GW2-B?
Both are Z-15-series 15 A SPDT basic switches with screw terminals. The GW22 has the short hinge roller lever with operating position 30.2 plus or minus 0.4 mm and 160 gf max operating force. The GW2 has the standard hinge roller lever with a longer operating position around 34 mm. Pick GW22 when space is tight and a shorter lever reach is needed; pick GW2 for the standard reach.
What does the B suffix mean on the Z-15GW22-B?
B marks the screw-terminal connection on the Z-15 basic switch. The bare (no-suffix) Z-15GW22 uses solder terminals. The Y-B variant uses M3.5 screw terminals with finger-safe covers. B is the most common form factor and what most panel builders order from stock.
How many operations can the Z-15GW22-B handle?
Mechanical life is 10 million operations min at rated operating force. Electrical life is 500,000 operations at the full 15 A 250 VAC resistive load. Pilot loads of 1 A typically run 5 to 10 million operations because the contact arc is much smaller than at full load.
Can the Z-15GW22-B switch a 24 VDC / 2 A DC solenoid?
Yes - the SPDT contact is rated 0.5 A at 125 VDC and 0.25 A at 250 VDC resistive, which covers a 2 A 24 VDC solenoid easily. For DC inductive loads, add a flyback diode across the solenoid coil to suppress the back-EMF that arcs across the contact on break. Without the diode, electrical life on DC inductive loads drops well below the rated 500,000 operations.
