TME's offer includes monostable electromagnetic contactors of the STM series by ZAMEL.
Contactors are designed for DIN rail mounting (TH35 type) in automation systems, where control of relatively high loads is required. The most important feature of these products is the galvanic separation between the control system and the load. ZAMEL modules have 2, 3, or 4 poles. Depending on the model, the following contact configurations are available: NC+NO, NC+NOx3, NCx4, NOx2, NOx3, and NOx4. With this choice, the supplier ensures that the needs of a wide range of customers are met. The maximum operating current of contactors ranges from 25 A to 63 A (see table below for https://tme.hk/en/product). Supply voltage: 24V AC/DC or 230V AC. Their operating temperature ranges from -5°C to 60°C, so they are particularly suitable for use in control cabinets.
ZAMEL contactors of the STM series are perfect for industrial automation systems, machinery resources, production lines, and warehouses - but they can also be used in automatic lighting installations, building automation, etc.
