Engineering Selection Recommendations
For applications currently using OPB880N51Z, the following active alternatives are available:
OPB880N11Z and OPB880N55Z maintain identical mounting type (free hanging) and all electrical specifications. Both parts are active products with current manufacturing support and full ROHS3 compliance.
OPB880T51Z provides electrical equivalence with chassis mount configuration, suitable for applications where fixed mounting is preferred over free hanging installation.
All three substitute parts carry active product status, ensuring long-term availability and supply chain continuity compared to the obsolete OPB880N51Z.
Frequently Asked Questions (FAQ)
Q: Can OPB880N11Z directly replace OPB880N51Z? A: Yes. OPB880N11Z matches all electrical parameters and maintains identical free hanging mounting type. The primary difference is product status: OPB880N11Z is active while OPB880N51Z is obsolete.
Q: What is the difference between OPB880N51Z and OPB880T51Z? A: Both parts share identical electrical specifications and sensing characteristics. The distinction is mounting type: OPB880N51Z uses free hanging configuration while OPB880T51Z uses chassis mount. Selection depends on mechanical installation requirements.
Q: Are OPB880N55Z and OPB880N11Z interchangeable? A: Yes. Both parts are parametrically equivalent with matching electrical ratings, sensing distance, operating temperature range, and free hanging mounting. Both are active products.
Q: Does mounting type affect electrical performance? A: No. Mounting type (free hanging versus chassis mount) is a mechanical consideration only and does not alter electrical characteristics, current ratings, voltage specifications, or sensing performance.
Q: Are all substitute parts ROHS3 compliant? A: Yes. OPB880N11Z, OPB880N55Z, and OPB880T51Z are all ROHS3 compliant and REACH unaffected, matching the compliance profile of OPB880N51Z.
