Product Overview
Four retained photographs show the same TS 236-11Z-M20 structure from different angles, including the plunger, housing, M20 label, cable-entry end and side profile. The inventory record omits the cable-entry suffix, so these photographs are presented as an M20 reference and not as proof of the exact stocked revision.

Specification Confirmation
| Item | Reviewed reference | Order check |
|---|
| Inventory model | SH-TS236-11Z | Confirm manufacturer and complete suffix |
| Photographed version | Schmersal TS 236-11Z-M20 | Do not assume M20 until the supplied label is checked |
| Alternative official version | TS 236-11Z-M16, article 151172700 | M16 dimensions and entry must not be mixed with M20 |
| Actuator | Plunger; head repositionable in four 90° steps in the reviewed family information | Confirm approach direction and head orientation |
| Contact arrangement | 1 NO + 1 NC; slow action in the M16 official reference | Verify the actual terminal diagram and contact continuity |
| Connection | Screw terminals; 0.75–2.5 mm² reference range | Confirm conductor preparation and terminal access |
| Thermal current | 10 A reference | Not a universal switching-current rating |
| Operational current reference | AC-15: 4 A at 230 VAC; DC-13: 1 A at 24 VDC | Values are from the M16 official reference; confirm the supplied version |
| M20 legacy housing reference | 30 × 58.5 × 30 mm; M20 × 1.5 entry | Confirm against the current physical unit before installation |
| M16 official overall reference | 30 × 30 × 73.5 mm; M16 × 1.5 entry | Alternative version only; do not apply to an M20 unit |
| Protection reference | IP65 / IP67 in the reviewed M16 page | Confirm the exact version, gland and installed sealing |
The 10 A value is identified as thermal test current in the manufacturer data. Final switching suitability depends on utilization category, voltage, load, inrush and the exact supplied suffix.
Buyer Confirmation Checklist
Resolve the suffix
Request a complete label photograph and confirm M20 × 1.5 versus M16 × 1.5 before selecting a gland, drawing or replacement.
Mechanical interface
Check plunger height and travel, approach direction, head orientation, housing dimensions, mounting points and entry clearance.
Electrical interface
Verify 1 NO + 1 NC operation, terminal numbering, AC-15 or DC-13 duty, load current, inrush and protective device.
Information Still Required
- Actual manufacturer and complete supplied-unit label
- Confirmed M20 or M16 cable-entry thread and matching current datasheet
- Exact stock dimensions, plunger travel, mounting drawing and terminal diagram
- Current project documents when certification or traceability must be verified
Frequently Asked Questions
Are TS 236-11Z-M20 and TS 236-11Z-M16 interchangeable?
Not automatically. Their cable-entry thread differs, and the matching dimensions, gland and documentation must follow the supplied suffix.
Does the 10 A field mean the switch can break 10 A in every circuit?
No. The manufacturer reference identifies 10 A as thermal current. Operational switching ratings depend on utilization category and voltage.
What should be checked for replacement?
Confirm manufacturer, full suffix, actuator geometry, housing and mounting dimensions, entry thread, terminal diagram, contact logic and real circuit duty.
Selection note: Do not finalize compatibility from TS 236-11Z alone. Resolve the manufacturer and M20/M16 suffix before ordering, wiring or installation.
