Product Description
- Magnetoresistive proximity switch for contactless detection of cylinder positions – ideally suited for automation systems with Festo T-slot connection, even under the most difficult environmental conditions.
- The SMT‑8M‑A is a compact, magnetoresistive proximity switch for T-slot cylinders, available in versions with PNP normally open contact (PS) or NPN normally open contact (NS) and optional cable lengths of 0.3 m, 2.5 m or 5 m.
- It is flexible in use, suitable for robot and energy chain operation, with a high degree of protection (IP65/68/69K) and LED status display.
- The robust design allows installation from above into the groove of the cylinder; the construction and materials are LABS-compliant and halogen-free – ideal for clean room or battery production.
- The switching speed of up to 130 Hz guarantees reliable signal detection even with fast cylinder movements.
