GG851S (GIGA4005B2PO/SIL2/US) is an ifm fail-safe inductive sensor with two PNP OSSD outputs, rated SIL 2 to IEC 61508 and IEC 62061 and PL d, category 2 to ISO 13849-1. It detects a steel target without a coded actuator and goes to the safe state when it is not correctly damped.
- Detection: enable zone > 10 mm, safe switch-off distance < 5 mm
- Outputs: 2x OSSD PNP (A1 and A2), 50 mA, compatible with EN 61131-2 type 1 and 2 inputs
- Response time: 5 ms to a safety request, risk time 45 ms; power-on delay max. 1000 ms
- Supply: 10...30 VDC, consumption < 30 mA; reverse polarity and short-circuit protection
- Housing: M18 x 1, white-bronze-coated brass, PBT sensing face, length 86.5 mm, flush mountable
- Environment: IP65 / IP67, operating temperature -25...+70 °C
- Connection: M12 connector, A-coded, 4-pin, gold-plated contacts
Used for safe position monitoring of guards, slides or machine parts where a steel part can serve as the target. Mission time is 20 years; operational life depends on ambient temperature (≤ 87,600 h at -25...+70 °C, ≤ 175,200 h at 10...40 °C).
SIL 2 to IEC 61508 and IEC 62061, PL d category 2 to ISO 13849-1, PFH < 1.0E-07 1/h. EMC to IEC 60947-5-2 and IEC 60947-5-3.
