Common Dimensions for Terminal Boxes

• Standard coated aluminum terminal box: 125 × 80 × 57 mm (4.92 × 3.15 × 2.24 in).

• Optional stainless steel terminal box: 100 × 100 × 61 mm (3.94 × 3.94 × 2.40 in), for connection to a remote transmitter.

• Terminal boxes are supplied with an M20 × 1.5 cable entry. Other optional entries are available (see datasheet).

Terminal box offset and integral transmitter dimensions depend on the sensor temperature range and connection arrangement (see datasheet).
