Series Overview - 316 Stainless Steel Prox Switch with Multi Voltage Capability
The ES-1 Series Proximity Switch is highly adaptable and can be used in a multitude of applications where a reliable signal is required. Its unique construction allows it to be used in some of the most extreme environments from -60°C (-76F) to 175°C (347°F).
A multitude of contact forms are available including changeover types SPCO/SPDT, DPCO/DPDT and 2-wire types Normally Open (NO) or Normally Closed (NC). A version incorporating line fault detection/monitoring is available with NAMUR output. Variants with Gold flashed contacts are also available for switching low currents. The ES-1 series offers versatility and applicability and multi-voltage flexibility by being able to switch either DC or AC at up to 240V.
The switch is designed to be mounted using the two fixing screws provided and is available hardwired with a range of cable and lead types to suit the application. The standard electrical conduit connection is PG9.
The presence of an external magnetic actuator is required for operation. Designed to sense at the top or side of the switch. Sensing ranges are dependent on the magnetic actuators used.
The ES-1 Series is covered by the following hazardous area certifications.
|Explosion Proof:||IECEx & ATEX Ex d/db/tb (Zone 1 & Zone 21) ¦ UL/CSA (Class I & II Div2)|
|Intrinsically Safe:||IECEx & ATEX Ex ia (Zone 0 & Zone 20) ¦ UL/CSA IS (Zone 0)|
|Other Regional Approvals Include:||EAC/TRCU, INMETRO, KCs, CCOE/PESO, ECAS ex, NEPSI/CQST|
The ES-1 series proximity switches meet the requirements of IEC 61508:2010 Routes 1H & 1S with Systematic Capability (SC3) as an element/subsystem, and are suitable for use in safety related systems performing safety functions up to and including SIL 2 with HFT=0 (1oo1) and SIL 3 with HFT =1 (1oo2).
