Schmersal TR 236-11Z-M20 Cable

Schmersal TR 236-11Z-M20 is a compact safety position switch with a single M20 x 1.5 cable entry and a thermoplastic, glass-fibre-reinforced enclosure designed for machine guarding. It offers 1 NO and 1 NC contact with a 4 A rating at 230 VAC (AC-15) and 1 A at 24 VDC (DC-13), backed by a B10D life of 20,000,000 operations and a mission time of 20 years, making it suitable for demanding safety applications. The device measures 30 mm x 58.5 mm x 30 mm, weighs about 55 g, and is double-insulated with IP65/IP67 protection, enabling reliable operation in harsh environments. The roller plunger actuating element requires a minimum 9 N of force, with a minimum breaking force of 19 N, and supports actuating speeds from 120 mm/min up to 1 m/s; actuator heads can be repositioned in 4 x 90° increments to suit mounting flexibility and a wide range of compatible actuators. Termination uses screw terminals M20 x 1.5 and accepts conductor cross-sections from 0.75 to 2.5 mm², with insulation rated at Ui 500 V and Uimp 6 kV. The TR 236-11Z-M20 aligns with EN IEC 60947-5-1 and EN ISO 13849-1 safety standards and carries approvals such as cULus and CCC, reflecting Schmersal’s emphasis on reliable, standards-compliant safety components for industrial automation.
