SLA2P-ZS 22mm Industrial Emergency Stop Pushbutton Switch (TÜV / CE / IP65 Waterproof)
TÜV Rheinland and CE certified 22mm panel-mount emergency stop switch featuring positive mechanical self-locking, ergonomic turn-to-release reset, IP65 waterproof/dustproof front seal, and self-cleaning silver-plated sliding contacts for medical devices, process machinery, and industrial automation consoles.
CNSL / Sanli Electric Engineering & Technical Overview
The SLA2P-ZS series emergency stop pushbutton switch is an industrial and medical-grade emergency power disconnect device designed for standardized 22mm (M22 / 22.5mm) control panel cutouts. Engineered to comply with international safety regulations including GB/T 14048.5 and IEC/EN 60947-5-1, the SLA2P-ZS provides high-reliability emergency intervention with positive mechanical latching that guarantees immediate circuit opening upon actuation.
Built with an intuitive push-lock and turn-to-release (twist-reset) mechanism, the switch prevents accidental resetting until an intentional rotary motion is applied by the operator. The switchhead is enclosed in an international standard high-contrast warning yellow safety collar paired with a high-visibility frosted mushroom operator (available in standard Ø40mm or compact Ø30mm configurations) for instantaneous tactile recognition in high-stress operational conditions.
Internally, the SLA2P series features structurally separated and electrically insulated Normally Open (NO) and Normally Closed (NC) contact elements, allowing independent dual-circuit operation across different electrical phases and polarities. The contacts utilize precision sliding, self-cleaning wipe geometry with heavy-duty silver-plated contact surfaces, preventing oxidation buildup and ensuring ultra-low contact resistance across thousands of operational cycles.
To streamline installation and maximize technician safety, the switch incorporates a finger-safe recessed terminal structure with captive combination screw clamps and guided wire channels. The front panel interface features a precision elastomer O-ring gasket providing IP65 waterproof and dustproof sealing, making it ideal for clinical medical instruments, cleanrooms, washdown food processing lines, and outdoor pump consoles.
Rigorously certified by TÜV Rheinland, European CE (Low Voltage Directive & EMC), and China Compulsory Certification (CCC), the SLA2P-ZS offers an operating duty cycle up to 1,200 operations/hour and robust temperature resilience spanning -25°C to +50°C for mission-critical automation systems.
Key Engineering Highlights:
- TÜV Rheinland & CE Certified: Fully audited and compliant with IEC/EN 60947-5-1 and GB/T 14048.5 international low-voltage switchgear safety standards.
- Positive Push-Lock / Turn-to-Release Operation: High-security mechanical latching prevents accidental reset, requiring deliberate rotary action to disengage.
- Universal 22mm (M22) Panel Mount: Standardized 22.5mm diameter mounting collar with anti-rotation locking ring and space-saving rear depth.
- IP65 Waterproof & Dustproof Sealing: Integrated front elastomer O-ring prevents moisture, chemical splash, sanitizers, and fine particulate ingress.
- Structurally Separated NO/NC Contacts: Contact blocks are completely electrically insulated and physically segregated, supporting multi-pole control.
- Self-Cleaning Silver-Plated Sliding Contacts: Dynamic wiping contact action clears oxidation and debris, ensuring reliable conductivity at both AC and DC voltages.
- Recessed Finger-Safe Screw Terminals: Combination Phillips/slotted clamp screws with wire guide funnels for rapid, secure, and touch-safe wiring.
- High-Contrast International Safety Design: High-visibility warning yellow base with ergonomic frosted concave mushroom cap (Ø40mm / Ø30mm).
