Product Description
Limit Switch CR137-BZ-T2 | Roller Lever, IP54, 10 A 250 V
The CR137-BZ-T2 is a heavy-duty limit switch engineered for reliable position feedback and safety circuits in demanding industrial applications. Featuring a snap-action, positive-break NC contact that ensures machine stop even during contact weld scenarios, this switch delivers failsafe performance. The IP54-rated glass-fibre reinforced housing provides robust protection against dust, oil, and high temperatures up to 80°C without performance degradation.
Key Advantages
- Positive-break NC contact - failsafe compliance per IEC 60947-5-1
- Fixed roller lever - consistent 1.5 mm pre-travel with no field adjustment required
- IP54 protection - suitable for both indoor and outdoor panel mounting
- 30-million-cycle mechanism - significantly reduces maintenance downtime
- Two M20 cable entries - facilitates fast wiring with optional double cable glands
