SN04 proximity switch with limit value Key benefits - Flexible switching options: available in normally open (NO) and normally closed (NC) configurations to match different control and signaling needs. - Dual wiring modes for broad compatibility: DC operation with three-wire configuration (10-30 V DC) and AC operation with two-wire configuration (90-250 V AC) for NO function. - Reliable limit sensing: designed to detect and respond to a preset limit value, enabling precise position or condition monitoring. - Compact square form factor: square sensor profile supports easy mounting and clean integration in confined or engineered layouts. - Simple integration across systems: the combination of NO/NC choices and multiple wiring options simplifies integration into diverse electrical systems. Specifications and usage - DC mode: three-wire configuration, supply 10-30 V DC, available in NO or NC versions. - AC mode: two-wire configuration, 90-250 V AC, normally open function. - Function: SN04 sensor detects a defined limit condition and outputs accordingly. - Form factor: square sensor body for straightforward installation and mounting in tight spaces. - Output flexibility: NO and NC options provide adaptable signaling for different control architectures. 2-3 practical use scenarios - Scenario 1: DC-controlled automation line Use the DC three-wire version (10-30 V DC) with NO or NC output to feed a PLC input, signaling that a predefined position or limit has been reached in a conveyor or robotic pick-and-place system. - Scenario 2: AC mains end-of-travel or safety interlock Use the AC two-wire NO version (90-250 V AC) to drive a switch input in a machine safety circuit or end-of-travel interlock, providing a reliable open or closed state when the limit is reached. - Scenario 3: Compact installation in equipment with mixed voltages In a machine with both DC control logic and AC mains components, deploy the SN04 in its appropriate mode (DC three-wire or AC two-wire) to achieve consistent limit sensing and signaling without changing hardware. Note - The SN04 is designed to respond to its preset limit conditions. Choose the wiring mode (DC three-wire or AC two-wire) and the contact type (NO or NC) that best fits your control system, ensuring correct compatibility with your voltage supply and input devices.
