SSA-EB1P-02

1. Overview

The SSA-EB1P-02 is a panel-mount electromechanical emergency stop (E-stop) push button from Banner Engineering (Banner part# 42201), part of the SSA-EB1 series within Banner's broader SSA-EB machine-safety line. It features a 40mm red mushroom-head actuator, push-to-stop/stay-put (latching) operation, and a twist-or-pull-to-release reset mechanism. The "-02" suffix denotes the 2NC (double normally-closed) contact configuration with screw-terminal wiring. Banner products in this family are also distributed and catalogued under the Turck-Banner brand (product ID 3042201 in Turck's system). The unit is non-illuminated; illuminated and lockable variants exist within the same series.

2. User Sentiment

No forum-based user sentiment or comparative reviews were found for this specific product. It appears consistently across dozens of global distributor pages (DigiKey, Mouser, RS Components, Newark, Farnell, element14, Radwell) without any notable complaints or praise in available sources. The product is treated as a straightforward industrial safety component — sourced by automation engineers by specification rather than reviewed subjectively. One used-condition listing on Mara Industrial notes the switch body is yellow plastic with a 40mm red twist knob, suggesting the housing color is yellow (not stainless), clarifying "SSA" does not indicate stainless steel in this model. New units sell at approximately $55–$62 USD across authorized distributors.

3. Real-World Applications

The SSA-EB1P-02 is used in industrial machine safety circuits wherever a panel-mounted emergency stop is required per IEC/EN 60204-1 or NFPA 79 — including CNC machinery, conveyors, robotics, packaging lines, and process control panels. Its 30mm mounting hole is compatible with Banner's OTB/VTB/STB Optical Touch Button mounting bases, enabling installation without a separate enclosure. It is sold globally across North America, Europe, Asia-Pacific, and South America through both OEM channels and MRO distributors. The SSA-EB1P-02-A01 variant (M12 QD, ISD Connect compatible) targets applications requiring Banner's In-Series Diagnostics (ISD) safety bus — e.g., integration with MQDMC-5xx cables for diagnostic monitoring.

5. Ordering & Compatibility

Street pricing: ~$55–$62 USD new at authorized distributors (Walker Industrial, iAutomation, Powermatic); ~$138 USD for SSA-EB1P-02-A01 (M12 QD/ISD variant). DigiKey PN: 2170-SSA-EB1P-02-ND. Lead time is typically 4–29 weeks from manufacturer (stock varies). Key variants: SSA-EB1P-02ECQ4 ($178, 4-pin M12 QD), SSA-EB1P-02ECQ5A/B (5-pin M12 QD, Safety BUS node), SSA-EB1P-02ED1Q4 (flush-mount, M12 QD), SSA-EB1P-02ECQ4-WC (with washdown cover). Accessories: SSA-EB1P-ECWC (FDA-grade silicone 40mm washdown cover, adds IP69, orderable as suffix -WC). ISD Connect compatible variants (SSA-EB1P-02-A01, part# 810952) require MQDMC-5xx series cables for diagnostics integration. Lockout/Tagout note: the lockable SSA-EB1M series variant is not an energy-isolating device per OSHA 29CFR1910.147.

6. Known Issues

The Turck datasheet lists a slightly more conservative ambient temperature upper limit of +55°C versus the +60°C cited by most distributor pages — users operating near the rated limit should verify the applicable datasheet revision. No field failures, quality complaints, or safety recalls were found in any available source. The product is long-established (multiple datasheet versions exist, indicating years of production continuity) and widely stocked by global distributors.
