Product Overview
The Z-15GQ22-B is the modern 'B'-suffix variant of Omron's Z-15GQ22 series basic switch — a 15 A SPDT pin-plunger-style switch with a panel-mount M12 hex nut body, a roller-plunger actuator for low-friction cam operation, and screw terminals rated for industrial field wiring. The Z-series is Omron's flagship premium basic switch family, the direct descendant of the original 1930s Micro Switch design, and used in tens of thousands of applications from coffee machine latches to CNC machine-tool doors. The roller plunger (vs plain plunger) reduces friction during cam approach — common in door-interlock and motion-limit applications where the cam scrapes past the actuator on every cycle.
Decoding the Z-15GQ22-B model number
Z-basic-switch model code: Z = Z-series premium basic switch family; 15 = 15 A rated current (vs 10 = 10 A, 01 = 0.1 A, 5 = 5 A); G = 'general' or 'medium actuation force' (vs H = high force, E = low force); Q = panel-mount body with M12 hex nut thread (for through-panel mounting with a single 12 mm hex-nut hole); 22 = roller plunger actuator (vs 0 = plain plunger, 1 = plain plunger no flange, 3 = hinged lever, 4 = long hinged lever, 5 = simulated roller lever, etc.); -B = modern suffix variant (mid-2010s onwards) with revised internal.
15 A rating — direct switching of industrial loads
The 15 A 250 VAC rating (6 A at 30 VDC, 0.6 A at 125 VDC) is sufficient to switch most industrial control loads directly without an interposing relay: pneumatic solenoid valves (24 VDC 50-500 mA), indicator lamps and pilot lights (24 VDC 100-200 mA), small motor contactor coils (24 VDC 100 mA to 2 A), and small single-phase motor loads directly (e.g., small fan motors or pump motors up to ~370 W). For larger loads, the Z-15GQ22-B drives an interposing relay coil (LY2N-J DC24 or G2R-2-SNI DC24V) or motor contactor; the relay/contactor then handles the larger load.
Roller plunger vs plain plunger — when to pick which
The roller plunger (the '22' in the SKU) replaces the plain pin plunger with an inline roller bearing — the lever rolls against the cam rather than scraping. Three advantages: (1) reduced cam wear — the roller doesn't scrape the cam surface; (2) lower operating force — the roller reduces friction and allows a ~30 % lower operating force than the plain plunger; (3) smoother operation — quieter, less vibration transmitted to the cam mechanism. The trade-off: the roller plunger adds ~5 mm length vs the plain plunger, which can be an issue in space-constrained installations.

Buying Checklist
- Pick Z-15GQ22-B for 15 A SPDT basic switch with roller plunger and M12 panel-mount body
- Pick Z-15GQ-B if you need a plain plunger — pick for low-cycle non-roller applications
- Pick Z-15GW2-B if you need a simulated roller plunger — pick for higher-position body and adjustable roller orientation
- Pick Z-10FQ-B if 10 A is sufficient and you need a slightly smaller body — pick for cost-sensitive applications
- Pick Z-15HW78-B if you need high actuation force — pick for slow or heavy cam applications
- Pick D4C-1220 if you need a fully sealed limit switch — pick for washdown or outdoor use

FAQ for Z-15GQ22-B
What's the difference between Z-15GQ22-B and Z-15GQ-B?
Both are 15 A SPDT basic switches with M12 panel-mount body. Z-15GQ22-B (this SKU) has a roller-plunger actuator — the plunger is replaced by an inline roller bearing for reduced friction during cam approach. Z-15GQ-B has a plain plunger — pin plunger that pushes directly against the cam. The roller-plunger has lower friction (cam doesn't scrape on the plunger during every cycle), quieter operation, and reduced cam wear; the trade-off is ~5 mm longer body length.
Can the Z-15GQ22-B switch a small motor or solenoid directly?
Yes — the 15 A 250 VAC rating handles most industrial control loads directly: pneumatic solenoid valves (24 VDC 50-500 mA), small motor contactor coils (24 VDC 100 mA to 2 A), indicator lamps (24 VDC 100-200 mA), and small single-phase motor loads up to ~370 W directly. For larger motor loads (1-phase 750 W+, 3-phase motors), the Z-15GQ22-B drives an interposing relay (LY2N-J DC24 or G2R-2-SNI DC24V) or motor contactor; the relay/contactor handles the larger load.
Is the Z-15GQ22-B safety-rated?
No — the Z-15GQ22-B is a general-purpose basic switch without direct-opening mechanism (DOM) certification. The SPDT contact is suitable for general-purpose position detection but not for personnel-protection guard interlock applications above Cat 1 / PL c. For safety-rated guard door switches (Cat 1 / PL c minimum), use the D4N-112G (plastic-body, 1NC/1NO, DOM), D4B-4111N (aluminum-body, 1NC/1NO, DOM), or D4BL-2CRA (guard-lock switch, 700 N holding force, DOM, up to Cat 4 / PL e).
How is the Z-15GQ22-B typically wired?
The Z-15GQ22-B has 3 screw terminals for SPDT wiring: COM (common), NO (normally-open), and NC (normally-closed). Wire the load's high-side to the COM terminal; the load's low-side connects to either NO (if you want the load ON when the plunger is depressed) or NC (if you want the load OFF when the plunger is depressed).
