Schneider Electric XSAV11373 Replacement for XSAV Series

Product Overview

Schneider Electric XSAV11373 Replacement for XSAV Series: Seamless Transition & Legacy System Compatibility

When your existing Schneider Electric XSAV11373 inductive proximity sensor reaches end-of-service or becomes difficult to source, a smooth migration path is critical to maintaining production uptime. The XSAV11373 is a Telemecanique XSAV Series cylindrical inductive proximity sensor widely deployed in discrete manufacturing, conveyor systems, machine tool automation, and process control panels across Europe and Asia. This replacement solution is engineered to deliver a drop-in upgrade experience — preserving your existing wiring harness, PLC input card assignments, and control cabinet layout without requiring panel redesign or program modification.

The XSAV11373 operates on a standard 3-wire PNP output configuration with a 12–24 V DC supply range, making it directly compatible with Schneider Electric Modicon M340, M580, and Premium PLC digital input modules such as the BMX DDI 1602 and TSX DEY 16D2. When migrating from an older Telemecanique TSX Series or Modicon 984 system, the sensor’s output signal characteristics remain within the accepted input thresholds of legacy I/O racks, eliminating the need for signal conditioning or interposing relays in most retrofit scenarios.

For installations where the XSAV11373 is mounted on a machine frame alongside other XSAV Series sensors — such as the XSAV11801 (M18 body, 8 mm sensing range) or the XSAV12373 (extended-range variant) — the physical form factor and M12 connector pinout are consistent across the series, allowing technicians to replace individual sensors without disturbing adjacent wiring or cable trays. The M12 4-pin connector standard used on the XSAV11373 is also compatible with Telemecanique XZCP Series pre-wired cordsets, simplifying field replacement without custom cable fabrication.

In distributed I/O architectures using Schneider Electric Advantys STB or TeSys island modules, the XSAV11373 connects directly to standard 24 V DC digital input slices without protocol conversion. For CANopen or Modbus RTU fieldbus topologies, the sensor’s discrete output integrates cleanly into the existing network without requiring gateway devices, provided the input module supports standard 24 V DC sourcing inputs — a specification met by the STB DDI 3230 and STB DDI 3420 I/O slices.

Control cabinet space is a frequent constraint in retrofit projects. The XSAV11373’s compact cylindrical housing (M12 × 60 mm body length) fits standard 18 mm panel cutouts and DIN-rail-mounted sensor brackets without modification. When replacing sensors in a Prisma or Spacial enclosure alongside Zelio Logic smart relays, TeSys D contactors, or Acti9 circuit breakers, the sensor’s cable exit direction and connector orientation allow routing within existing cable management channels.

For customers upgrading from discontinued Telemecanique XS Series sensors (XS1N12PA340, XS2N12PA340) or older square-body XS2 variants, the XSAV11373 provides a functionally equivalent replacement with improved EMC immunity and IP67 ingress protection — suitable for washdown environments and outdoor machine enclosures. The sensing face material and operating frequency (1.5 kHz typical) are compatible with standard ferrous target detection applications on steel conveyor guides, actuator end-stops, and rotary indexing tables.

Seamless Upgrade Solutions

A complete XSAV11373 retrofit typically involves more than a single sensor swap. In practice, field engineers sourcing this replacement also require complementary components to complete the migration without delays. The XZCP1141L2 pre-wired M12 cordset (2 m, PVC jacket) is the most common companion item, providing a ready-made cable assembly that connects directly to the XSAV11373’s M12 connector and terminates at the control cabinet terminal block without re-crimping. For installations using Schneider Electric Advantys STB distributed I/O, the STB DDI 3230 24 V DC digital input slice accepts the sensor’s PNP output directly, eliminating the need for interposing relays.

When the retrofit scope extends to the PLC rack, customers frequently pair the XSAV11373 with a BMX DDI 1602 16-channel digital input module for Modicon M340 systems, or a TSX DEY 16D2 for legacy Premium PLC racks — both of which accept 24 V DC PNP sourcing inputs at the sensor’s rated output current. In control cabinets where power supply capacity is being reassessed during the upgrade, the Phaseo ABL8REM24030 24 V DC / 30 A regulated power supply is a common addition, providing stable supply voltage for multiple XSAV Series sensors and I/O modules on the same rail.

For machine builders integrating the XSAV11373 into new panel builds alongside existing Telemecanique TeSys D LC1D contactors and Zelio Logic SR3B261BD smart relays, the sensor’s discrete output connects directly to the relay’s digital input terminals without signal conditioning. Where signal isolation is required between the sensor circuit and the PLC input card — particularly in high-noise environments near variable frequency drives — a Phoenix Contact or Schneider Electric signal isolator module inserted at the terminal block resolves interference without modifying the sensor wiring.

Retrofit Guidance FAQ

Q: Do I need to modify my PLC program after replacing with XSAV11373?
A: No. The XSAV11373 is a direct functional replacement with identical output logic (PNP NO). Your existing ladder logic, function block, or structured text program requires no modification, provided the input address assignment remains unchanged in the I/O configuration.

Q: Is the wiring pinout compatible with my existing M12 cordset?
A: Yes. The XSAV11373 uses the standard M12 4-pin A-coded pinout: Pin 1 = +24 V DC, Pin 3 = 0 V, Pin 4 = Output (PNP). This is consistent with all Telemecanique XSAV and XZCP Series cordsets.

Q: Will the sensor fit in the same mounting hole as my old unit?
A: Yes. The M12 × 60 mm body fits the same 18 mm threaded panel cutout. Lock nut torque specification is 15 N·m maximum — identical to prior XSAV Series units.

Q: Is the XSAV11373 compatible with Modbus RTU or CANopen fieldbus systems?
A: The XSAV11373 is a discrete output sensor and does not communicate directly over fieldbus. Its PNP output connects to a digital input module (e.g., STB DDI 3230 on Advantys STB CANopen island), which then reports the signal state over the fieldbus to the PLC. No gateway or protocol converter is required.

Q: What is the sensing range for non-ferrous targets?
A: The nominal 2 mm sensing range applies to standard ferrous (mild steel) targets. For stainless steel, the correction factor is approximately 0.85×; for aluminum, approximately 0.4×. Adjust target distance accordingly during commissioning.

Q: Can this sensor operate in a washdown or outdoor environment?
A: Yes. The IP67 rating confirms protection against temporary immersion up to 1 m for 30 minutes, making it suitable for food processing, outdoor machine enclosures, and high-pressure washdown zones.
