Emergency Stop Button Lockout — SBL51

The PROLOCKEY Emergency Stop Button Lockout is model SBL51. Use the specifications and product images below to confirm suitability for the intended lockout/tagout application.

Product features

• Made of polycarbonate, temperature resistance -20℃ to +120℃.
• Specially designed for locking Siemens emergency stop switch or emegency stop switch with shields in tight locations.
• Suitable for chemical, food, pharmaceutical and other situations.
• Can be managed by 2 people at the same time.
• Many emergency stop buttons have a raised shield or guard ring around them to prevent accidental bumps, and Siemens switches in particular use a housing profile that a generic universal lockout cover often doesn’t seat against cleanly. This design is shaped to fit both cases rather than needing a separate adapter.
• The lockout has two separate lock holes, so two different workers can each apply their own padlock to the same isolation point. Neither can remove the cover and re-energize the switch until both locks come off, which supports a two-person or dual-authorization lockout procedure on one control point.
• It’s built around Siemens’ housing profile, so a close but non-Siemens shielded switch should be checked against the total and inner diameter measurements before ordering. A mismatch in shield height or diameter can leave gaps a standard lockout wouldn’t have.
• The transparent PC construction lets supervisors see the switch’s position and any labeling through the cover without removing it, which matters for quick visual verification during a lockout audit.
• Prolockey makes several emergency stop lockout variants for different diameters and mounting styles. The SBL01/SBL02 series covers 22.5mm-30mm switches, and SBL07-08 covers 22.7mm-29.8mm, if this one isn’t the right fit.
